    would i buy em again......yes.

    Ok, had a few sets of these, wear em at work all the time so the eventually get "killed!" Sound quality is pretty good with my ipod. They keep the noise out pretty well too. The only downside is the cable (which is lop sided (on purpose,) is really annoying but that"s just me, and the length seems to be quite a bit shorter than previously? Would i recommend em, yes i would, for how much they cost, (less than fifteen quid) they work well and are pretty durable. I usually kill em off at around twelve months, which with the conditions i work in i find acceptable.

    Ridiculous design

    I was disappointed that it wasn't made clear these earphones are of type where the lead to one side of the earphones is much longer than the other (apparently one of them is supposed to be worn behind the neck). I just can't see the benefit or point of one of these over traditional earphones when both leads are the same length. Worse thing is they can't be worn from the front like normal because of this and can't be adjusted. This is the second time I've ended up buying earphones in this design where it hadn't been made clear on the listing which has been really annoying to the point it's made me do my first review! This needs to be made clear. Sound quality is good but the design makes them uncomfortable to wear

    The only headphones I buy and use

    I have purchased these several times. Sometimes because I lost them. Sometimes because I put them in the wash. Sometimes because they stopped working. I knocked a star off because they give up before the 2 year warrantee, which is OK, if you've bought them original and they can be replaced (they cost £45) but since I buy them so cheap on Ebay, I can't complain that much.

    Probably not genuine Sennheiser product.

    I've purchased these exact same headphones in the past and to be brutally honest, I believe this product is not a genuine item. From the quality of the stitching on the storage pouch to the sound quality from the earbuds, everything is below par. Don't get me wrong, for a cheap set of earbuds they do the job ok, but nowhere near the quality of a genuiy Sennheiser product. They've been relegated to my emergency headphone drawer and I've spent 30 quid on a genuine set direct from Sennheiser. When compared to my previous CX300-II, the pouch is totally different, the stitching is poor quality, the snaplock opening is a lot softer and the logo print is not as well defined. The cable length is a lot shorter and the sound quality is nowhere near as crisp as it should be.

    Best in ear headphones

    These are easily the best in ear headphones for this price of only £12! This is now my 3rd pair of these as I keep losing them, but I wouldn’t buy any other in ear headphones, especially if they cost more than this. These are better than others I have tried that cost much more than these, eg SoundMAGIC E10 and Beats. I own some Beats over ear headphones that cost £200 pounds and these sennheisers actually sound better! They are also way better than the AKG ones that come with the Samsung smart phones. They are perfect for exercise as they are light, have good sound isolation, are small enough to fit comfortably in your ear, also have necklace style wire which is good for keeping the wire out the way when running/exercising. They also sound amazing and can handle anything you throw at ...
