I've owned two pairs of CX300s now, one black and one white. I got the first set about five years ago, and was astounded by what a difference they made to listening to music on my iPod. The only reason I am on my second pair is that the first got squashed in an accident, and broke, but that was not Sennheiser's fault!
MP3s, because of their sound compression, tend to make music more 'tinny' than it was intended to be, and these headphones, with their surprising bass and warm tone are the perfect antidote. I listen to a lot of Hip-Hop, which by it's nature needs good bass, and these tiny headphones pack a surprising punch in that department. I have no idea how because of their size, but that's not the point.
One thing I would say (being as I am something of an ear officionado...) is that headphones that sit within the external ear canal itself, as these do, are an acquired taste, which some people will not get on with. Those with frequent ear infections, a history of perforated eardrums, sensitive skin, hearing aids or wax buildup may want to avoid them.
You'd be mad to use them while driving, cycling or anything similar as they effectively act as earplugs. This noise-blocking ability is great though, as it means you can use them in busy noisy places without you music being ruined - think screaming kids on public transport, long-haul flights, university libraries where people go to socialize rather than study... etc. It also means that people around you won't be bothered by what you're listening to, which is one common courtesy that often is forgotten.
All in all a great pair of headphones.
Addendum: after advice from an experienced Dooyoo reviewer I will add that these headphones come with three pairs of different sized silicone (I think) ear grommets, for different sized ears. Mine fitted the middle ones. In my experience almost all ear canals are a medium, but nice to get a selection nonetheless
During a brief time when I was without headphones having left mine in a pub I borrowed my other half's headphones which were these Sennheiser CX300 in ear headphones. I was slightly dubious at first as I have not had much luck with headphones in the past staying in place in my ears whether that be sitting or walking I just couldn't seem to find a pair that suited my ear shape.
The colour of my headphones was black with a silver band round the ear bud bit. The wire is approximately 1.20m which makes them great for carrying in your bag or pocket without being stretched. The wire splits about 30cm from the ear buds with the right side of the wire being longer than the left to allow for less pull during wear. Each headphone is labelled the common 'R' and 'L' for ease of application, though their shape allows you to wear them in either ear without the sound quality being affected. This is a great advantage over other headphones. The jack plug connection is the common MP3 and iPod adaptor being 3.5mm and angled. These are very lightweight feeling compared to previous headphones I have used.
The great thing about these in ear headphones is that they come with three options of earbud adapters being small, medium and large fit. This allows you to be able to choose the best fit as well as the best sound result to suit your preference.The buds easily slide onto the end of the earphone and are a comfortable and flexible rubber material. One thing to be careful of with these adapters is to watch that these don't fall off without you noticing, I have done this when carrying them around in my handbag. You do get a carry pouch included so I would advise you to use it to avoid losing these and having to order replacements.
These headphone side easily into your ear canal and their flexible shape and design ensure that they stay there, I would describe the shape as almost mushroom like. This snug and secure fit ensures that no sound quality is lost during wear and it really does work. They look modern and stylish.
These headphones have high-quality dynamic speaker systems for powerful and bass-driven stereo sound. The design and fit allows for high passive attenuation of ambient noise so little to no sound loss is experienced during wear. I have to say the quality of sound is fabulous it feels like you are completely shut off to the outside world and give a great music experience. The bass from these is very deep and gives a full music experience and no distortion is experienced with increased volume. The technical data is as follows;
Frequency response 18 - 21000 Hz
Impedance - 16 ohms
Sound pressure - 112 dB
Transducer principle - Dynamic
In My Opinion
These are the best headphones I have ever used and as a result went and bought myself a pair when my o/h was pestering for his back. They are extremely comfortable and for a change I don't have to constantly keep putting the headphones back into place, even with my in-ear piercing, once these are in they are in for the long run. No outside noise is experienced during use and it really is great sound quality compared to anything else I have used before. I would certainly recommend these headphones to friends and potential buyers.
These retail for approximately £15 - 20 which is quite frankly a bargain when you look at what someone like Apple charges for their comparable product.
Having a good set or earphones can drastically improve one's enjoyment for music; it is probably the best thing you can do to get more enjoyment out of your music. You could do a lot worse than investing in a pair of Sennheiser CX300's.
So straight in to the most important factor when considering a new pair of earphones; how good is the sound quality?
Well the CX300's sound quality is excellent, the bass is very deep without being overpowering, and the mid to high range tones are really superb, and for the price bracket probably the best in its market.
You can now pick these up, I believe, for just under £20 on Amazon which you cannot complain about, when they first came out they were around £40; so a real bargain.
Buyers must be very wary as there are a lot of cons out there making cheap illegal reproductions of these earpieces, you can generally tell because they will be selling for around £5 on eBay, but nonetheless it is something you should be aware of. There are plenty of guides on the internet letting you determine whether you have been conned or not, my advice, stick with a reputable dealer.
Although I had no problems with the cable a few of my friends did, it is quite thin, and therefore seemingly quite vulnerable to general wear and tear, they have had problems with the cable splitting, and just generally not being very rugged.
One thing that really is a fatal flaw in the earphones however, is the dreaded "left earphone syndrome" with lots of people complaining about the right ear piece packing in after continual use. I myself had this problem and it was inevitably the reason I got rid of them, and replaced them.
This really is down to personal preference, some people really do not like their earphones being pushed down the ear canal. The benefits are massively reduced outside noise and more of the music getting to your ears. Whereas forcing something in youe ears can be very uncomfortable. In my opinion I think they are great, there is less chance of them slipping out and you can enjoy your music just that little bit more.
For under £20 I believe that these headphones really are an excellent purchase, with the bass being one of the highlights of the earphones. Watch out for cheap imitations because you will be disappointed, and you have been warned about possible reliability issues...
The Sennheiser cx 300 headphones are an excellent pair of headphones for those on the move and are both small and light but also very powerful and eesigned to fit snugly into each ear. They have a good sized lead and insert simply into your mp3 player with a jack. They cost about £30 which seems a trifle expensive for a pair of earphones but they will pay you back by being very reliable and easy to carry around. Anyone who likes to have something to listen to while they wait for the train will appreciate owning a pair of these.
The earphones themselves are small bulbs rather than the circular earphones and are very comfortable to wear. I have had some earphones in the past that have hurt my ears after a while but these are very good on that score. I hate it on the train too when the constant announcements from that robotic female voice keep interrupting what you are listening to and you can't quite manage to block the sound out. With these earphones though you can go into a world of your own and the way they fit your ears and the manner in which they convey the sound means that nothing will come between you and your music or whatever you are listening to.
The earphones have felt casings which come in three sizes and the cord is black. In terms of life expectancy, I've had these for a good few weeks and there haven't been problems yet although I am wary because in my experience earphones are a pain to keep replacing when they go on the wonk. So far they've been very reliable and the audio quality is better than most earphones I've had in the past. If you are looking for a lightweight and comfortable pair of earphones to carry around then these are worth considering.
I bought these earphones a long time ago when I wanted some new ones for my iPod. I don't think the Apple ones are that great, especially for my tiny ears! At the time, I wasn't too knowledgeable about what good brands are in headphones apart from the usual Sony, etc, so I had a look around on Amazon and found that these Sennheiser ones were quite popular and pretty reasonable in price. I bought them for around £12 and they are an excellent buy. I think its hard to find this model now, as it has been preceeded, but you can pick up a newer model for within £20.
I bought black but at the time they came in either black or silver colour (just the actual round headphone piece is coloured, not the whole thing, wires etc) I think they also come in all white these days, to look a bit like Apple. They are the in-ear style, so rather than sitting on your ear opening, they fit further inside. I was new to this whole in-ear business, so found it quite weird to adjust to at first, but now wouldn't have it any other way!
They come with ear adapters which pop onto the earpiece to help you fit into your ear, and they come in in 3 sizes, so there is a small set for little-eared folk like myself, and then a medium and larger size. They are quite easy to pop onto the earphones, and don't come off easily, which is good. They sit securely in your ear and I have worn them both in the house and when jogging or at the gym.
The design is very slick and minimalistic, and they look modern and inconspicuous. The sound quality is brilliant, and I could really tell the difference between these and the standard ones that came with my Apple iPod. The music is so clear and crisp, and the fact they are in ear means all the music is directed directly into your ears rather than being partly lost to the outside world. They are noise cancelling, so unless you have them at a really high volume, people that are nearby can't really hear what you're listening to, which is important, especially if you use public transport! Equally once you have them on, you can't hear much that's going on outside.
Each earpiece is marked right or left, as you would expect, and the earpiece has a small 'S' logo unique to Sennheiser, so those people who know their Senheisser from their Skullcandy would know which brand headphones you are wearing (should you be bothered about this kind of thing!).
Mine have lasted ages and have not felt the need to buy any more, although they now have the improved version of this model (CX-300 II) and come in Eco packaging.
Ideally you should wear these with the wires hanging inside your clothing so that you don't pull or catch the wires by accident. Would perhaps be useful to have some kind of clip so you could clip it to your clothes if you're like me and can't always be bothered weaving them through your clothing? Also, there is no volume adjusting button on these earphones, which doesn't bother me, but some people might like their headphones with something like this.
I'm not sure if there is a recommended way to clean these earphones, but I just wipe them and the ear adaptors with piece of tissue every couple of months to get rid of any dirt or wax build up (nasty, but inevitable unfortunately!).
Sennheiser has made a name for themselves by producing excellent quality headphones like these, and others within their range, and if I were to purchase another set of headphones, Sennheiser would probably be the first brand I would consider.
I purchased these earphones for £9 off eBay as a remedy to the appalling earphones that came with my iPod Nano. They come packaged in what can only be described as bulletproof plastic as it took me nearly 5 minutes to crack it open.
The CX300's came with three sizes of ear buds and after finding the size that fitted the snuggest it felt like I'd muted out the world. A problem with these is I use them for running and every time you jolt the cable the sound is amplified through the ear buds, although a good thing to note is no matter how fast I run they never fall out.
I find the sound quality to be nearly as good as my home cinema surround sound system, there is no distortion and the treble is sweet and clear. The bass however I find is quite variable, it only works if the ear buds are pushed fully in, if they move an mm out of place the effect on the bass is dramatic.
The build quality of the CX300's is amazing I've caught the ear buds several times in things and they haven't cracked or fell apart (unlike my iPod earphones!).
Having recently acquired an iPod Nano, I just could not get on with Apple's standard issue white earphones. I found them quite painful to wear for any length of time and they kept falling out of my ears, so, I went looking for a suitable alternative.
Having had a very good pair of Sony's Fontopia earphones ("ear canal" type earphones with swappable rubber buds much like the ones on these) a few years ago, I found the form factor very comfortable and user-friendly, so after a quick look at similar options on-line, I decided to plump for the Sennheiser CX300.
PRICE & PACKAGING
I ordered mine from Amazon for £16.99, opting for a version with "eco-friendly" packaging. They are offered in silver and black, and I opted for the latter (for some reason the DooYoo illustration shows a pink version, which I have never seen).
The eco packaging was novel (to say the least), being made up of successive layers of corrugated cardboard, cut to fit around the ear buds and cables, and held together by a promotional sleeve with Sennheiser's product details on it, and a special eco-friendly pin badge made of recycled materials.
The packaging is 78% recycled cardboard with no glue or plastics used in its construction. To be frank, it was all very nice, but I'd be a hypocrite for pretending to push a green agenda - I opted for this version of packaging because it was a few quid cheaper than the alternative (ironically, this is no longer the case - the standard packaged version is now slightly cheaper).
These small, discreet and lightweight earphones come with three different sized buds, so you can choose which ones are most appropriate for your ear. They are a snug fit and do a very good job of blocking out outside noise.
The "noise-cancelling" effect is almost too good, as the few near misses I have had with quieter road traffic would attest. To give you some idea, I often use them when walking in high noise, high traffic areas and can usually listen to music at medium volume without any problem.
The downside is that this type of earphone amplifies your heartbeat and your footfall and you can audibly hear yourself swallowing when listening to softer music. As such, it's probably not suited for activities such as jogging, or any other rigorous exercise (they would probably fall out anyway), however it seems fine for light, normal walking, and after a while, I didn't really notice this effect.
Despite looking fragile, the build quality is excellent and, as such, these earphones have proven to be quite durable. The 1.2m flexible "Y" cable is asymmetric, with the left side much shorter than the right, allowing them to be worn either behind the neck, or as I prefer them, in front. The standard phono jack finishes in an L-shape, which is convenient, as it minimises the protrusion from small devices like my iPod. My one niggle is that the thin cables are forever getting tangled!
They are very comfortable to wear, and I had none of the noticeable "ear fatigue" I have had with similar "hard" in-ear headphones. It is very easy to forget you have these on sometimes.
In terms of performance, they are a definite improvement on the bog standard iPod earphones. With the ear plugs properly fitted (you need an airtight seal with your ear canal), the bass is deep, rich and clear, and the treble manages to be sharp without being painful or distorted. I have an eclectic taste in music, and it seems to perform just as well with Linkin Park, as it does with Stan Getz, the Gladiator soundtrack, or spoken word.
All in all, these are superb, value for money alternatives to the pre-packaged earphones provided with most MP3 players, and will help you get the most out of your music. However, some people may not like the in-ear experience, and the blockage of ambient noise and the rustling evident when the wires are jostled make this a no-no for sports use.

The Sennheiser CX300 in ear canal earphones produce a high quality and top competing sound. If you have never owned a pair of in ear earphones (like myself) the sensation at first can be weird. The sensation can be likended to having water in your ears, and all you can hear is overly amplified noises of you breathing. However when you then connect these beauties up to your Mp3 audio device (with a 3.5mm headphone jack) you can really see the top brand have succeeded in making a harmonious set of audio devices. Another great feature about this model is the removeble and interchangeable ear phone pieces. This allow you to ensure the ear pieces fit snuggly into your ear canal thus providing you with the top quality sound we have learnt to expect from Sennheiser. One critism I do have is that some of the adjustable ear peices can sometime detatch themselves without you knowing, and they can be lost. Without that tight fit these headphones are near to useless!
I am very happy with the Sennheiser CX 300: the sound quality is superb. It has a very strong bass with a large range (I even had to turn down the bass on my mp3 player). You even hear the lowest vibration, but also the high tones are very good. The mid tones could be slightly better, but that can be solved by adjusting the bass and treble on your MP3 player and raise the volume up.
I noticed with these headphones even better, how bad the quality of many MP3 are. I always listen to 320 Kbit, but you can now even hear the poor quality of 192 Kbit from the cheap MP3 players.
You need to get used to insert the ear buds in your ears: you need to open your ear with you one hand, and you need to push it deep into your ear with your other hand. If you don't do it the right way, then the sound quality is very poor and that is not the way how this headphone should be used!
Is the sound bad? This means you don't wear it the right way.
Since you have to put them so deep into your ears, you don't hear any noise from the environment and this means that the volume does not need to be so high.
Since everyone has different ears, there are 3 different types of rubber caps whom can be paste on the caps.
The plus points:
+ It has a super sound (very low bass strong, clear and good dynamics)
+ Available for a good price
+ Rubber caps for all ears
+ The environment has no burden of the sound, because the caps are deep in the ears
+ Lower volume, so less hearing damage
- You need to get used to the ear buds comfort!
- Wire gets pretty fast in a twist.
The CX 300 are high-quality stereo ear-canal headphones with powerful, bass-driven stereo sound for listening 'on the move'. Ear adapters in three different sizes ensure a perfect fit, high wearing comfort and an excellent attenuation of ambient noise. The CX 300 are ideal for use with MP3, CD, MD, or DVD players and many other portable devices.
