Before starting my job in September, I walked/cycled everywhere and wouldn't go anywhere without music. At the beginning of my student life I had tried a whole range of different cheapish headphones without enjoying any of them. I decided it was time to buy a pair of more expensive, comfortable ones. I had a long look around and my dad convinced me to turn to Sennheisers. The CX300-IIs were on offer at £25 when I was looking so I took the plunge.
What are the good features?
Not only are they very good at cancelling any noise from the outside, they produce great sound quality. In my opinion, they are noticeably superior to any other in ear headphones I have tried. The bass from the headphones is great, really improves your listening experience.
The headphones come with 3 different ear bud sizes which makes for a comfortable fit, whatever your ear size. In addition, there is a tidy little pouch provided which makes for easy storage/transportation. The length of the cable is also pretty much spot on.
Although the 3.5mm jack that you put into your music device is relatively sturdy, I would prefer a vertical jack. A vertical jack would allow the cable to come straight out of my pocket but with the 90 degree bend, the cable has to bend back on itself. The only time I had a pair of these fail on me was because of a loose connection at the 3.5mm jack. Since my first pair broke (2 years of regular use) I have bought another pair and they are as great as ever.
At this price, do not dismiss them as useless tat, embrace the cheap price and you'll soon appreciate the brilliant sound quality without noticing a huge hole in your bank balance!
My previous pair of headphones so I looked to this company to buy some cheap headphones! These cost around £29.99 now online and in store and I thought they must be pretty good! I was however very disappointed!
My previous headphones I've used include lady gaga monsters, gaga 2.0 and the monster DNA headphones. Also the sony in ear ones which cost about £9. Why Am I telling you this? - Because there are many reviews on headphones that are created with very low knowledge of WHAT is out there!
The cord isn't a flat one which means these will tangle very easily. Another PET HATE is the fact these headphones have one ear wire longer than the other!!! This means if you want to tuck these under clothing, you have almost twice the length of one ear which means you need to tuck this extra wire under your clothes! Otherwise it just hangs out and looks stupid!!
The sound on these are really awful, and were such a let down. I used these with my iPhone 5 which can normally adapt to any headphones, but wow are these awful! I could hardly hear the music and the beats were louder than the vocals?? I had to turn up them up really loud which actually hurt my ears - I never have this with other headphones. Even at the loudest I could hear cars on the road and in ear headphones normally block some sound out! The bass was weak and the sound was weak too.
The connector is an L shape one - which I love as I hate straight ones that stick out too much. The downside is that this L shape is quite large.. and is cured so it does actually stick out
I only have one pro with this product. I bought it and returned it the next day. I couldn't believe how bad these were... such a let down!!!!!
Sony have some great £9 headphones. To be honest, they nearly border the previous pairs i've had that were beats and monsters!!! I've now bought some upbeats so I will write a review on here once I listen to them a bit!!
Please do not buy these, they are such a let down, a waste of money, and you can buy SUCH better headphones for 1/3 of the price!!!!!
Specialists in sound isolation
Sennheiser was established in 1945; by the sound pioneer / Founder: Fritz Sennheiser (1912 - 2010)
Fritz means a condition in which something does not work properly
- - -
Hearing about the death of a 'sound near centurion,' Fritz Sennheiser on Sennheiser earphones makes for a grand sense of total completion - "Ah, my work is done here," this is a bit like a song writer who spends his life writing songs, in a bid for them to be sung back in unison from all corners of the globe - there is no better tribute to one's success. Fritz parted three years ago; however his audio legacy lives on via the plethora of audio devices, all shapes and sizes. If he tunes in, there would be no greater reward to his pioneering endeavour. The number of plaudits who raved on about the Sennheiser audio capabilities still vocalises with admiration the quality of audio the brand has achieved. I was one of them, once. I marvelled at the ear-canal ergonomics of the ear-phone heads. I adored the industrial strength packaging which required industrial strength cutting contraptions to even dent the packaging casing. I thought, 'this manufacturer really cares about the welfare of their products in transit, 'you wouldn't put it pass them to package ear-buds in a steely capsule; when-ever it opens liquid nitrogen wafts into the air.'
The earphones have the intrinsic detailing of a precision device which must means supremacy quality. Colour is exquisitely 'Noir, black' - Blacker than black, if that is possible; the blacker the device seems the better the quality - colours come in: 'Blacker than black and whiter than white.' I partly blame Apple's gaudy colour charts with the ridiculous colour terminologies. Does colour really determine gargantuan amounts of quality, functionality and durability? It seems to, I only buy black or white earphones - it doesn't happen by accident, I've been duped into it by the 'blacker than black and whiter than white' gurus of marketing and colour. The colour neutrality denotes perfected audio performance, although what aren't clear are the audio laboratory reports at differing sound frequencies, in-balance to volume. How do you measure quality of audio? Unless, the audio-bullies come out of their coveted laboratory cubicles and give some credibility to a 'sound report' - audio is an individual thing. Everyone hears music / every form of audio differently.
Three sizes of ear-buds are available in accessories - child to adult size. There is no notable discomfort after prolonged usage either, so the Sennheiser on product design gets the full allotted five stars. Not easy accomplishments as my ear canals are prone to complaining after short bursts of earphone wearing, up until eight years ago; when the ear canal got a hearing to the products ergonometric design. The CX 300 is designed for comfort; like a slipper, comfort oddly is prioritised differently depending on age of the reviewer. Overall, my hearing is good so I can tell the difference to a high, middle, or low sound frequency - the CX 300 from varying Hz (Hertz) is highly efficient - lower audio frequencies tends to be at its most optimal level. Not ideal if you're a 'Bee Gees' or a 'Scissor Sisters' fan - Sennheiser could introduce you to the wonders of classical music - 'Brahms' or maybe a 'Schubert' - German acoustics compliment German and Austrian composer compositions. The wire isn't overly long so tangling isn't a concern unless of course you use the earplugs while you're doing rapid exercises, extravagant head and neck movements wouldn't help the Sennheiser audio experience, if you're determined to exercise while being wired up to the CX 300; volume control is integrated into the earphones so you needn't stop doing the aerobic activity. Useful; albeit, not a reason to purchase it.
Compatibility wise - iPod is the main device these phones have been made for - but also other MP3 players are compatible, as stated in smaller text. You can't help but feel Sennheiser's marketing ploy is to board the iPod gravy train. 'iPod' is in a bold text on the packaging, if it was based on sound, it'll be deafening.
Buy online at 30 GBP - but please note, you'll only get twelve months of quality usage, in reality you'll get 3 GBP worth per month. Poor duration, therefore it is a case of good quality audio versus lessened duration quantity. Whether it is value for money, it depends on the user's circumstances. I value comfort, therefore I don't mind the fee / duration issue / quality and comfort comes with having a Sennheiser product.
Sennheiser is the sound pioneer, not a 'pie in ear.'
Firstly, if you are unaware of the meaning of this review title, please head here:
Now that's explained, let's move on to the earphones.
I like my music and therefore earphone/headphone quality is very important to me. I bought these a while ago, but they have since sadly broken. However I recently found out how to fix them - more on that later! For a decent price, these are great earphones with good sound quality and excellent bass. As in-ear earphones, they provide the best sound quality with noise-cancelling power so that you can listen to your music in peace without interruptions from the outside world.
These earphones have a very simple design, which looks great. Available in either white or black, the earphones come in one of those impossible to get into boxes alongside several earbuds for different size ears. These earphones fit well in my ear with the medium size ear piece - you just have to try them until you find one that fits best! They are also pretty good at staying in whilst exercising. The earphones themselves are like buds, which fit into your ear. The quality of these buds seems reasonable and they are light too. Handy 'L' and 'R' letters on the earphones mean you can quickly see which side goes where. The connection is rounded and slightly flimsy compared to some other ones I have seen, so I would beware of bending it too much whilst wrapping the earphones/folding them up.
These earphones provide a good precise sound range. Comparing them to very expensive earphones, they may lack a bit of clarity. Besides this they are superb for the price paid. The bass is an important feature of these earphones. This is considerably better than most earphones I have had in the past. It gives a well-rounded thumping bass, which can be made even better by turning the bass EQ on most MP3 players. All music sounds great on these, but I must say they are particularly good for songs with a lot of bass - notably bass guitar and drum sets.
As I mentioned before, my earphones broke. This happened three months into having them, which is not long! I soon figured out a way to fix them, and I have no idea how it worked. I used a very small pin to carefully take off the wire mesh that covered the earbud, which had stopped working. Looking inside, there was a fair bit of gooey wax! I know, disgusting! I got rid of all of this, put the wire mesh back on and pressed it down to fit back into place. After trying out the earphones again, the right ear bud which had previously broken was working fine again! I have since bought another pair of different earphones, but I am now still able to use these ones when I please. They seem like a reasonably solid set of earphones besides this problem I had. I would be careful with the 3mm jack connection though as it seems a bit more flimsy than it could be, and this is often how earphones break - through damage to this jack!
*Value For Money*
The retail price for these is £44.99, which goes to show their potential quality. However you can buy them online for around £25 these days. They used to be a lot cheaper when I bought them - for around £15 on Amazon! The price has gone up now, perhaps due to their popularity. You can also find them offline in electric stores.
These are a great pair of earphones, of reasonable quality which deliver superb bass and a good all-round sound quality. They are pretty good value for money, although they have previously been even better! I would certainly recommend them for someone looking for a new pair who plays a lot of music with bass!
Most of the internet agrees that Apple's bundled headphones are terrible, and you should get then replaced ASAP. Lots of sites recommend these for those on a budget, so I felt it had to be done. And I'll tell you what, they're brilliant.
I am fast becoming an audiophile, but I don't have the budget to be blowing £1000s on headphones. But these are excellent considering they are under £30. Bass, mids and trebles are all there in equal measure, with none of them sounding too overpowering or harsh. I'd actually put these ahead of my Bose in ear headphones in terms of quality sound.
Now, what about durability? In the past, this is where Sennheiser have let me down. I had a noise cancelling pair of earbuds similar to the CX300s, and while they were pretty good for the money, the left earbud stopped working after a few months. But so far, I've had no issues with the CX300s whatsoever. However, the cable does feel a little thin, but it does seem to be withstanding all the abuse I've given it so far.
One more thing, the cable is asymmetric; one side is longer than the other. It is a tad annoying but not so much that it detracts from the overall experience.
In short, get a set of these to free yourself from the dreadful bundled Apple earbuds and start to listen to your music, rather than just hear it.
I've gone through many pairs of headphones over the last few years (mostly due to losing them on a regular basis!) As a result I have tried a fair few brands and types, but I keep coming back to Sennheiser.
These headphones are incredibly comfortable in the ear (with different sized earbuds to make that easier). The quality is also excellent, I have not yet broken a pair, which is a problem I suffered regularly with other brands.
There is minimal noise leakage, which makes the listening experience pleasant for you and means that those around you don't have to share whatever you are listening to! This makes them an excellent choice for the daily commute. It also means that you don't have to have the headphones up too loud (which is always a plus) but you don't lose any of the noise-cancelling experience. This is something that sets it apart.
One thing to note is that these headphones have the two earbud wires the same length, so may not be for you if you prefer headphones with one shorter wire for one ear.
The fact that I always end up with these every time I need a replacement pair of headphones speaks volumes, and I would thoroughly recommend them (especially if bought on special offer!)
I was given these headphones for Christmas, and I really loved them. That was until they recently broke...more on that later!
For starters, these headphones fitted my ear really comfortably, and didn't keep falling out like some other headphones have. I could keep wearing them for long periods without feeling any irritation in my ear. I listen to music constantly and so having something that I wouldn't notice I was wearing was important to me.
The sound quality is excellent, and I also found that when they were on I was able to hear music really well in spite of background noise, e.g. traffic, trains, planes.
As their description says, they are 'bass-driven', and so the bass in any music is pronounced. For me this was an asset as I often turn the bass level up on my speakers anyway, but for those who prefer to have lower levels of bass this might be a deterrent.
So as I said, these headphones are now broken, and I think this was because I may have got some sand into one of the earpieces while on sunbathing on holiday - it suddenly stopped working. So my one warning is to be careful with these, it's very frustrating when they break!
Since my first i-pod i owned 3 pairs of cx-300's. Through natural life span and breakages i had to replace. I tried skull candy and beyerdynamic both of which still work but they were just all wrong so i paqid the money and bought a pair of cx-300-II's. Why did i ever change. I had read reviews on amazon for upto £50 in ear phones and was convinced £50 were better than £25. This is not the case. I have used these on different generatin ipods, itouchs, iphones and these devices have an impact (mainly on loudness ie, newer product the louder it can go)
The main things are
Sound quality. 10/10. whatever you pair it with the sound is clear, no distortion and a middle of the road sound. The skull candy was muffled bass, the beyers more for classical with no bass. The cx-300-II's get it right for all kinds of music with clarity.
Build quality. 10/10. I have never had a pair of sennheisers that have lost the sound from one of the ears. Enough said.
Ergonomics. 10/10. I thought that all the ear-pieces by all the manufacturers would be the same as they look that way.But that is not the case. Some of the rubber is too hard, some too soft and again sennheiser get it right down the middle. they stay in the ear andare comfortable.
I remember the first time I put these headphones in, I was sat at work in an atmosphere where yes I'm trying to listen to my music but if someone says my name I need to be able to hear them. I put these in and it felt like someone had just put some sort of soundproof bag over my head. I couldn't hear a thing of the outside world, the ear buds fitted perfectly (although there are alternative sizes should you have bigger or smaller earholes). However for my clearly very average ears these the standard was a perfect fit.
The sound from them was so much better than I've heard from other headphones of around the same price too. They had a good range and you could really hear the bass going in all different kinds of music whether it be dance or rock (mood swings) the Sennheiser headphones would deal with whatever I threw at them and deliver great quality of sound every time. Whilst they may not be the best on the market for the sound they produce, for the price of them you certainly cannot argue with it and I was certainly pleasantly surprised by the sound.
"Leakage" has been a big problem particularly at work where sometimes I may want my music loud but without other people hearing. These I found I could have on much louder than any other headphones I had tried and nobody near me would comment, obviously being in the bubble of music and ear bud I can't comment from the outside but normally somebody would say something. As mentioned above if I had both headphones in even without music on it was like having semi decent ear plugs in and with music I was apparently oblivious to any noise around me. These were great for blocking out the outside world and just tuning into my music.
Durability has also been another huge problem I have had with headphones where wire connectors inside have become loose due to the not particularly caring treatment they may have to withstand on a daily basis. Screwing them up and stuffing them in my pocket never seemed to affect them except the mass array of knots that I'd have when I pulled them out my pocket. Also unlike some other headphones I have had the actual ear buds seemed to stay on these rather than slipping off in my pocket or bag.
All in all these were great headphones (until I lost them the other day) but they were that good that I am going straight into town on Monday to buy another pair, and if that doesn't say it all I don't know what does. There are better headphones out there if you want to pay a lot, but for the mid range these are great!
I own and have owned many and various ear and headphones over the years and I have a fairly large collection. One of the most recent ones I purchased was the Sennheiser CX 300 II Precision Noise Isolating Ear-canal Phones. These retail at the costly sum of almost forty quid but I managed to track down some on Ebay for just £15. I had read and heard a lot of excellent reports about these phones and decided to splash out a bit and get something better than those cheap store bought ones I usually get and which tend to last me about a fortnight.
The Sennheiser CX 300 II Precision Noise Isolating Ear-canal Phones are an excellent example of what a decent headphone should be. They deliver quality rich sound and at the same time have the remarkable ability to block out and buffer any outside noise and interference, giving the user quality sound with a bass base.
I use them with my mp3 Player, my iphone and my iPod and the connection is wonderful. They are robust yet compact and lightweight and are an excellent fit into my ear. I have had some problems in the past, particularly with cheaper brands of store bought earphones, in that I am unable to get a good fit into my ear, especially my right one for some reason, yet with the Sennheiser CX 300 II Precision Noise Isolating Ear-canal Phones there never seems to be any problem in securing a good fit.
They deliver an excellent sound quality with none of the nasty tinny rattle which is evident with cheaper earphones. The only downside to these is that because they are such a secure and snug fit into my ear, I have had some experience of the rubber buds keep falling off. I have bought replacements as I have lost one or two outside in car parks but the same problem has re-occured. For this reason I just have to make very sure that I remove the earpiece very carefully after each use to ensure the rubber stays put.
All in all a very good product and highly recommended.

Listening to music is one of my favorite pastimes. Whether driving a car or going for a walk or jogging I always make sure I have some music. Since my mobile can play music (such as Mp3 files) it's obvious that I listen to my music mostly via my mobile. The only problem I had were that the headphones that came with my headphones weren't really sufficient. The sound quality is a disaster and after one month the cable was almost broken. It was clear I needed some new headphones.
This is the headphones Sennheiser CX300ii. The headphones are black, but I have also seen them in white if I'm not mistaken. The headphones are compatible with various devices like mobile phones, game consoles, MP3 players and so on and so forth. The headphones came in a standard plastic packaging and a small carrying case was included which I never use. The cable has a length of about 1.2 metres and I think that's normal for headphones. For me is ok but I could have done with a bit longer.
The sound quality is just great. Listening to music makes it really fun again. Even on the phone, everything is much better/clearer. I can only say that you can hear the difference between cheap headphones and these headphones. The audio jack has a gold cover which apparently helps the sound quality. The earphones are in-ear earphones which also helps improving the sound quality and the bass. They fit comfortable in my ear and don't fall out when I'm jogging.
The price of these headphones is just horrendous for something this small and I paid 45 pounds for them. After the bad experience with my other headphones I was ready to invest in a good pair of earphones and I'm glad I did.
Expensive headphones, you have to say. But the tone and sound quality is just wonderful. You notice the difference immediately. The only thing they could improve is the length of the cable but it doesn't bother me that much. I would recommended these.
Never really knowing much about headphones I picked these up because they had decent reviews and the cost wasn't off putting. I had also heard of Sennheiser (German Brand) and recognised it as being one of the leaders in audio headphones.
I also travel quite a bit so thought they would do the job when plugging them into my laptop/mobile phone/portable DVD player.
I read that these are optimised for portable systems (including games consoles) and to be honest they do the job very well. I have been missing out on years using generic headphones not believing the hype. They are well worth the money for something which when you think gets used for hundreds of hours should make the decision of buying them a no brainer. The fact that you get a control too which i have never had before means i won't be going back to the old school type.
They are also well built, feel very sturdy and sit very comfortably in my ears. In the pack you get different sized (3) buds so you should be able to find one that fits your ears. They also look the part. They cable length isn't long, 1.2m so whilst it does the job I could have done with it being a little longer. When I go jogging sometimes it feels like it is pulling on the player so I have moved it to a chest pocket which has not solved the small problem. They are light but that probably doesn't get considered by anyone buying headphones. I liked the fact that the packet stated you get a 2 years guarantee. I have had friends break headphones on many occasions and knowing if anything goes wrong it is good that the manufacturer is there to help.
If you are after a pair of headphones which offer decent bass, very clear sounds which reduce background noise you could far worse that picking a pair of these up. The sound truly is so much better than what you get with standard gadgets, throw out whatever you get with your itouch etc, and pick a pair of these up. You'll have no idea of how important headphones are until you do.
Lastly it is nice that you get a small carry case which makes the experience of buying the Sennheiser CX 300-II Precision a quality product, here you can keep the spare buds.
Bring that music to life
4 out of 5
I have bought many pairs of these earphones - why you may ask? Well, they keep breaking! However, these are superb earphones whilst they last, and this is why the Sennheiser CX-300ii's create such a paradox. They are in-ear earphones, which means they are efficient in delivering excellent bass and are also very noise-isolating. They have pretty good specifications and can deliver a very full, loud and clear volume at the same time.
You can either buy these earphones in the black colour or white one. I have had both (why not? I mean I've had so many pairs...) but I must say that the white ones are personally preferred! You can buy them in standard plastic packaging or the more green eco-packaging, which consists mostly of cardboard. The latter is actually better too, as it's a lot easier to get the earphones and accessories out. The plastic box is a real pain to open, and you'll end up yanking the earphones out and possibly breaking them!
Having mentioned 'accessories', I must add that you get a little Sennheiser pouch to keep your earphones in, along with different size earbuds (small, medium, large). These will definitely fit all ears, unless you are planning to buy these for your pet elephant - if you are, please let me know WHY you have a pet elephant! I use the small earbuds and they are quite comfortable - they don't hurt when I move my jaw or head and they don't really hurt after a long time with them in either. They fit in the ear well and stay in during exercise, which makes them excellent for running and other sports.
The wire of these earphones is good in the way that it doesn't wind up on itself, like some may do. However, being a wire, it can generally get a bit tangled in a pocket or bag. It's certainly long enough but not ridiculously long that you have inches of wire hanging out your pocket! One of the earbuds is on a shorter wire where it splits (the left one), so you can bring this one straight to your left ear, whilst wearing the right earbud wire round the back of your head (from left to right), for a comfortable fit and no annoying wires on the front of your neck!
The sound quality from these is superb. The bass is excellent and they are very powerful earphones. They have a good frequency range too from 19Hz to 21,000Hz, which is a little better than most other earphones, meaning you will have a more complete sound. Despite the power of these bass-enhanced earphones, the clarity is unmistakable. Even at louder volumes, they maintain crystal clear quality and simply deliver a very full impressive audio.
The earbuds themselves are slightly round in shape, with a Sennheiser logo on the outside. They aren't terribly unique, but you won't be seen as stupid wearing them! The audio jack has a gold covering to it, which helps to improve the sound quality too. This audio jack is pretty sturdy, and has never been the obvious problem for the earphones breaking. What seems to be the problem is one of the ear pieces - usually the left one, which randomly stops working after a while. This is terribly annoying and I don't know why it happens. If you buy these, it is certainly worth using the pouch as it helps to protect them from any damage. Also, keeping them out of bags with heavy books in and other equipment will prevent damage, which can cause them to break immediately! Mine tended to last longer when I stopped wrapping them round my iPod and just carried them loosely in my pocket instead. However you do get a great 2 year guarantee with these, which comes in VERY useful when they do break.. if they do! I have used this many times, contacting the company that has sold me them, and they were always happy to send me a new pair or give me a refund, providing I send the old ones back (namely Amazon.co.uk this is, or 3rd party retailers through them).
The retail price may appear to be around £40, but do not fall for this! You can get genuine ones for around £15 online. Many sites sell these, and they are extremely popular as they are cheap and of great quality - good value for money! They are certainly worth buying, and if yours do unfortunately break, at least you have the guarantee as a back up. They are ideal for music with plenty of bass, but are excellent providing full clear sound for all types of music. They set the atmosphere nicely when used to watch videos or movies too.
Thanks for reading
I've had 2 pairs of Sennheiser CX300 II Precision in ear headphones over the last year. I found them very comfortable to wear.The sound quality is good enough. These are bass driven headphones so if you don't like to hear loud bass in your music these probably aren't the ones for you!
Too much bass wasn't really a problem for me because I only really used them when I was walking or travelling on the train or bus. I wasn't looking for superb sound quality, just something to listen to to pass the time.
I won't be buying these head phones again though for a couple of reasons:
1 - They don't last long! The first pair I had packed in after only 3 months. The sound started to come and go on one side, sometimes one side would be louder than the other side and then it stopped producing sound completely! The same happened with the second pair except the sound just disappeared without any warning at all! There's nothing worse than having 2 earphones in and only getting sound from one side!
2 - I noticed that when I was wearing these while walking or doing anything that involved moving around, I could hear the vibrations of the lead rubbing against things coming through the headphones!
It's because of those two things that I won't be buying these headphones a third time! In my opinion, paying more than £20 for something that only lasts a few months is a waste of money when there's much better earphones out there with better sound quality that last much longer.
Whilst apple has pretty much conquered everything music related, with iTunes, the iPod, the iTouch..... there is one place it's left lagging..... HEADPHONES.... for years iPod users have had all their music in wonderful quality on their iPods and had to listen too it through appalling, tinny, white things.
I've had a pair of Sennheisers for going on 5 years... they are without a doubt the best small headphones you can buy for under £50.
*SOUND QUALITY; you wont be able to find better sound quality, these reproduce the music you're playing faithfully. It takes a bit of getting used to if you're familiar with apple's, but it's well worth it.
*IN EAR; unlike apples and many others, these headphones fit snugly into your ear. This is benificial because it drowns out ambient noise, meaning that you'r music doesnt have to be played so loud, reducing ear damage.
*QUALITY; many earphones break after a month or two of use, the plastic falls off, the wire breaks etc... these will last for atleast.... well.. from experience i've had a pair about a year before CHOOSING to replace them. Occasionally the plastic budds fall off or go missing, but they're easily replaces
*I mean this literally... due to the... larger than normal price tag associated with these there are plenty of people selling fake ones on the internet, so beware.... if youre finding these for £5 on ebay... they're not going to be real... trust me, the real ones are worth the extra cash...
Offering a powerful, bass-driven stereo sound with greater clarity and improved dynamics are the CX 300-II Precision ear-canal phones. The various sizes of ear adapters provided in the package allow for a personalized fit as well as a high passive attenuation of ambient noise. Also, the asymmetrical cable design ensures a high wearing comfort as you listen on the go.
