    I already owned a pair of these and came to the reviews to see if others' disappointment was similar to my own. Reading no end of reviews I learnt a lot, first I thought that perhaps I'd bought counterfeits or that as others had mentioned the much lauded "bass-driven sound" was a con. Bass was certainly absent on mine. Then I read further about "the fit" and others' experiences experimenting with the different sized rubber cups that come supplied. I played around with mine and low and behold the bass is there, rich deep sound. I know nothing about headphone technology but a millimetre move deeper into your ear releases all of the sound that these things were clearly designed for, bizarre, but a relief to discover the sound quality. On the down side as all humans' ear canals must vary a bit there may be some people who find it impossible to achieve this fit and can't enjoy the full quality of these great earphones. Once I'd achieved the bass sound I wanted I noticed the other common observation, when I move my head the sound of anything brushing the cables is magnified inside your head, if you clear your throat the sound is hard-wired directly into your brain too. The other point that perplexes people is one cable being longer than the other, the instructions with mine clearly indicate that this is to pass the left phone behind your head before inserting. And there is an advantage to this as it clearly does minimize the sound effect of any friction with the cable. My main criticism would be the great importance of achieving the correct fit in order to release the full sound and the poor instructions that come with them in reference to this issue.Read more ›

    I have avoided the ear canal type headphones for a long time but after my latest headphones broke I looked around and found that most companies are concentrating on the ear canal types so decided to give them a go.

    After being a happy Sennheiser customer for years I decided to go with the CX300's after reading other customer reviews. I made sure that I bought from Amazon's main store rather than the cheap marketplace versions as I have tried some fake CX300's off Ebay and they are awful.

    The best tip I could give is to find the best fitting of the three supplied ear pads and to ensure that the headphones are securely in your ears. I went for the medium ones at first but found they were coming out of my ears with the slightest pull on the cable. The larger ones were fine, making the phones stay in my ears and also making sure of no sound escaping. It's important to push the headphones right into your ears as the bass tends to be the thing that suffers when the phones are not pushed in well.

    If you are not used to these style of headphones then beware that as they are right in your ears you can hear things that you might not normally hear with headphones If you are walking and listening you can hear every footstep reverberating through your body! Furthermore, if you are eating you can hear every sound from inside your mouth very clearly! It's weird but part and parcel of using these sort of headphones I'm afraid!

    Once the headphones are fitted well the sound quality is very rewarding with great bass, excellent bright treble and the biggest bonus for me was hearing midrange sounds of things like guitars and keyboards which is where you truly hear parts of the music you will have never heard before.

    Having had them for about 3 months now I love them, but it wasn't a case of love at first listen because as a lot of reviewers on here have mentioned, like other inner earphones, they pick up a lot of noise that you wouldn't notice with conventional in ear phones. When I first put them in they sounded great, but the first time I walked to work in them, I thought they were a disaster, because they transmit the sound of your breathing, footsteps and the cord brushing against your clothes straight into your ears, and it seemed they were fatally flawed for this reason.
    *BUT* within a few days your brain stops taking in the stuff it doesn't want to hear, and all you notice is the music, which is as good as you'll hear from a set of earphones not costing silly money.

    The other thing that you have to get used to is getting a proper seal when you put them in your ears, because if you don't, they sound pretty brash and tinny. This is a bit tricky at first, but you soon get used to it and whereas I had to fiddle around for ages when I first got them to make them sound as they should, I can just pop them in my ears now and get the desired results straightaway. Once in properly, the CX300s reward with a rich and deep sound that conveys a lot of detail, and as they shut out so much extraneous noise, really allow you to lose yourself in your music - so much so that you need to make an extra effort to look out for traffic and muggers as it's very easy to lose track of what's happening in the outside world.

    A great upgrade to replace the cheapo 'phones that come with most if not all personal audio devices
