I purchased the CX300 after wanting a decent pair of earphones that weren't your usual break in a week ones.
After reading reviews I found the CX300 to be a popular choice, the money I had spent on poor quality headphones so far I thought was about equivalent to the £18 cost of the Sennheisers so I went ahead and purchased them.
They are REALLY bassy, have a rubbery premium feel to the cable. But I wasn't impressed with the build quality of the actual ear bud. They look great but it was a little flimsy feeling.
I have since bought a pair of Creative ep630 which are the exact same shell but with different internal parts and branding.
In comparison the Sennheisers were bassier out of the package which the Creative's lacked but had more high end frequency and required some 'breaking in'.
The ep630 are still a good alternative as they cost around £10 - £20 but you can pick up CX300's for £16-£20, so in that case Sennheiser's all the way!
The Sennheiser CX-300 headphones have been out for around two years now, and are generally recognized to be great value in ear headphones for everyday use. They are cheap (cost around £18) and they also have a very good sound.
The headphones fit inside the ear, and therefore reduce outside noise that you do not want to disturb the music. Some people will find these headphones to be quite uncomfortable, as they can itch a bit. But Sennheiser has kindly included three different ear bud types in the packaging, so whatever size your ears are, they are bound to fit, making it a more comfortable experience.
In terms of durability these headphones last for a while. They are designed to be cheap everyday use headphones, so they wont just fall apart after a few hours use, in my experience I have found these headphones to be quite sturdy and strong, with everyday use I found that they lasted around 6 months, which in my opinion is impressive, I have had other headphones before that have not even reached the one month mark, but these do far better than that.
Now the important factor that comes when buying these headphones, the sound quality. I found the bass to be very strong, and the higher sounds were sharp and clear. These headphones for me did not provide anything that was truly exceptional, but for the price range the sound quality certainly is very good, and I was impressed with the performance I was given from these particular headphones.
The price is the real killer here, at a safe £15-£18, you cannot go wrong with a set of buds like these, for a similar price from other manufacturers, you would not really be finding the same sound quality and durability, but something far worse, it is also generally quite hard to find a set of in ear headphones for the price, but in this area the CX-300s get full marks.
Due to their long term success, Sennheiser has now released these classics in a multitude of colours. You can now purchase them in blue, red, silver and black, giving lots of choice in buying them and allowing customers to purchase the exact style that suits them the best.
These headphones are very small, but the wire that they are attached to is about a metre long, in my experience I found this to be very useful, the mp3 player that I was using with them could be used at a distance and they would not come out of my ears or out of the mp3 player socket, they were good in this regard, but the wire is very thin and if you're not careful it could break easily.
I would recommend these headphones to the daily commuter, who wants a pair of headphones by a well known sound brand for a cheap price. These headphones are made by Sennheiser, one of the famous names within the sound industry, and sound very good for the price. The in ear system also helps to drown out most if not all background sound, making for a much better user experience, they are also durable and will not break while commuting for a while. I would certainly recommend these headphones, as I have had a great amount of pleasure, they have not failed me yet, and perform exceptionally well for the price that I paid for them, well done Sennheiser, you have created a very special product here, 5 stars.
Sennheiser are a very good and so are these headphones however they weren't as good as I hoped. They provide good sound quality however they are not suitable for runners as when you run you here an amplified version of the wires hitting your legs which is pretty annoying.
They are great value for money and compared to headphones of a similar price range they are very very good, but unlike most people I prefer my apple headphones over these mostly becasue of the sound disruption caused when walking/running.
They fit very well and come with 3 different bud sizes so they fit most ears and this means better sound quality than most. Due to their good fit they also up up to high volumes which is useful for public transport as it blocks out the noise pollution from the bus/train so listening is not interupted and you can enjoy all your favourite songs without having to listen to the drone of an engine.
I got a set of these when hanging around at an airport and i broke my headphone! So i went over the curry's or comet (whichever) and had a look at what they had. They had my headphone i just broke but they were pretty expensive(more than normal) and i thought for the price they were i would try these for the same price. I was hesatent at first as my old headphone were a bargin £4.95 and really were amazing and felt i should have gone with what i new. At first the shape of them trough me a bit as they are very small, but the sound is'nt! So comfortable light dont even notice them in ear to honest, The bass on them is good and very clear from the bottom to the top, the only thing to moan about is in my haste to catch my plane i bought them in sliver and on the way out of the shop they had them in black which looked way more stealth!
The Sennheiser CX300 used to be great value for money, but the world moves on and with the power of the internet comes choice and competion. If you shop around you will find much better options than the CX300. I am not for a minute saying the CX300 is not good. Its just there is much better.
I used to use the CX300 and apart from the cable I thought they were good. I now use a pair of Soundwise TC20 and they are better in everyway. My girlfriend uses the T4 and it is very similar to the CX300 except the jack is straight and the cable is better quality, oh and its half the price.
Soundwise is just one brand there are others:
These headphones are brilliant. They have the best sound quality I have ever heard from a pair of headphones. The headphones come with 3 different sets of earbuds, small, medium and large so that the headphones will fit. As the earbuds are designed it is important that they don't fall out, the sennheiser never fall out because they fit snugly in the ear. I have had these headphones for six months and they still have good sound coming from them as thy are very reliable. The last point to make is that you must clean your ears at regularly so you don't get ear wax on the headphones
The CX300 are ear canal or IEM (Inner Ear Monitor). They were originally released by Sennheiser as pro equipment and are related in design to both the Creative EP630s and an earlier Sharp model. Sennheiser whilst using similar molds ensure that the drivers inside are made to their exacting standards. The drivers are not speakers as such but they are armatures and so unlike most speaker type headphones work their best straight out of the box with no need to burn them in.
This was my first pair of IEM as I was not sure that I could cope with something in my ear canal. I find with the medium silicone tips that I can wear them for many hours at a siting and can even use them in bed with my head on one side.
Sound, they do attenuate external noise very well and it is possible to still run them at medium volume settings when in a room full of people talking and a surround sound TV with active subwoofer working.
Quality of Sound
I have compared them with pro monitor full sized headphones suchas the HD280 pro, noise cancelling travel headphones CXP150 and my own GRado SR60.
Bass is very easy to follow, they are more bass forward than any of the refference cans. Vocals are just a bit back in the mix and the very top end treble such as cymbals lacks the sparkle of my Grado SR60s. That said, I now use these CX300 even at home in quiet environments. They are a bargain for the price asked and will eat alive any stock buds that come with ipods etc.
You can even run,cycle or work out in them, but beware, you may not hear traffic approaching and you will have to run the cord under a vest or tape it to your skin in order to stop it banging against your body. Cord or cable noise will transfer directly to your ears by microphonic vibration through the cable, just like a Tin-can telephone unless you take this precaution.
If like me, you find that the standard earphones supplied with most mp3 and cd players never quite fit properly and fall out every time you move slightly too fast, then the CX 300 are well worth a shot. Once you've found the right combination of ear adapters to create a perfect fit, the noise attenuation is incredible! The first time I used these was on a noisy rush hour bus through Bristol. They shut out just about everything around me leaving me with clear, uninterrupted music without having to crank the volume up. This'll also save your batteries!
