    I bought these white earphones because they were a lot cheaper from Amazon itself at the time (£19 I believe) and I only wanted to use them in bed. I needed a reasonably priced good quality pair of earphones with noise isolation and these are perfect. These made it possible to sleep through most of the really loud noise when the road was being widened. They lasted many months longer than cheaper ones before I finally rolled on them once too often :) I highly recommend them as they have a good range of sound and decent bass but not over-powering and of course very good noise isolation. As usual they come with different sizes of ear tips to find the comfortable fit but unlike some I’ve had in the past these are even comfortable in bed. Another good thing about them is the cable on the right one is much longer than the left, as it goes round the back of your neck, so you don't have to struggle to read the tiny L and R, you just feel for the longer side. Also, you won't lose them if you need to take them off temporarily.

    Great sound as expected for a Sennheiser product. Plus the choice of different adapters make these the only in-ear headphones I've used so far which properly stay in my ears - even whilst I'm running.

    When I got them, I was quite pleased with these earphones. I used them in the gym and on the train. However, after about two weeks, one earpiece stopped working. They are just too fragile for day to day use.

    After reading the review on these headphones I felt obliged to create my own to share my opinion on one of the best purchases I have ever made!

    Bought a pair of these from HMV in the UK for about £35 (reduced from £40) in about March 2009. I used to be the kinda guy to buy crappy £5 headphones from argos because I mistreated them and they often broke. After buying these Sennheisers I realise what false economy that was! I've had them ever since, and used them every day since then. In the rain, in the sun, and I have crammed them in and out of my bags/pockets more times than I would dare to count, and still they work perfect! It's upsetting to read people having such negative experiences with them as this has been the one thing that has outlasted all other tech things I've owned (even managed to kill a laptop in a shorter time than I've had them!).

    The other reviews are correct that if you bang the wires you can hear it, but aside from that, the quality of the sound is incredible for the price.

    If mine ever break, I will be buying a replacement pair of these that day without hesitation!

    This is the second pair in white in 6 months that have gone faulty. The sound just seems to disappear in the left ear phone. Contacted Amazon again and they have sent me a form for posting and refunded my money without question. I will not be buying these again. What I cannot understand is that I also have a pair in black that are fine, touch wood.

    I bought these at the same time as buying an iPod 8GB Nano as I had read many times that the supplied Apple phones were pretty mediocre - which they are! The CX 300 lls were a massive step up both in terms of clarity and detail, plus they have a good, deep and above all, tuneful bass with a sweet and relaxing treble.
    Be warned, though: it's true what other reviewers say that you must get the buds properly positioned, but this is easy if you follow the earlier advice to reach over the head and gently pull up one ear with the opposite hand whilst inserting the bud. The 'hand over the head' system ensures that the ear canal is fully opened so that the bud will then fit snugly inside. Doing this will give you the deep tuneful bass: put then in loosely like the standard phones and your music will sound like a couple of mossies trapped in a tin can!! (Could this be the reason behind reports I have read of poor audio performance?)
    Also, remember to loop the longer cable to the right bud round the back of the neck: this will minimise any microphony from the cable being touched.
    They come with a clever sprung top storage purse, so are easy to store, and so far have seemed very durable in use.
    At this price, they are well worth the money.

    I bought an earphone around 10:30am yesterday and got an despatch email around 11:30am. The most efficient despatch ever!
    Got the earphone this morning, looks really classy with lovely details but sadly I ordered a white one but got a black one.
    I contacted the seller immediately and got an email within an hour which says they're sorry for the mistake and that they're going to send me a which one immediately also I can keep the black one as an appology.
    I'm very happy with this purchase. Now I can see why the seller has such high score on amazon:)
    Thanks for everything.

    I decided to get these as an upgrade after my last pair of Sennheisers, which were getting worn and tatty. I have to say, these are once again, absolutely excellent - far better sound quality than the standard iPod/iPhone headphones and for a really good price. I've had them for over a year now, and they still sound great, really clear and loud - with excellent bass achieved when you learn the knack of sealing them in tightly and use the right sized earbuds out of the selection included.

    The inline headphone control is highly useful as it prevents the scramble to reach your device when someone is trying to talk to you! However as for the other accessories, I haven't really used them much - the pouch is merely acting as a storage container for the cable organiser and spare buds.

    Having said all this, I have had them for over a year, and they are definitely starting to show it - they are used often, and regularly jammed in and out of pockets/bags etc. so this is somewhat expected, and there is nothing to be done to stop white coloured electronics showing dirt! However what I did find is that the rubber sections on the jack plug and split began to degrade quite badly - they picked up the dirt the worst, and really showed the wear and tear, and eventually I just pulled them off!
    Similarly, the little bits of rubber on the cable next to the headphones themselves quickly detached themselves from the headphones, leaving them free on the cable.

    For the price they are absolutely brilliant, and I would definitely recommend getting them from Amazon, as they are far cheaper than the high street where they retail for between £40-50. The sound is great, and in fairness, the dirt/wear factors are partly a result of the white colour and the rough use they get, so I won't mark them down for this, especially as they still work well and are so cheap!
