I agree with the previous review of these. I bought them as they are named, specifically, "Sport" headphones; and, being from a reputable and - usually very good - dealer, Sennheiser, I was expecting these to be pretty solid. How wrong I was was. The first thing you'd think about Sport headphones would be - right, give them to someone, make them run on a treadmill, and see if they stay on. Clearly the developers didn't do this, as they would have realised that the headphones don't stay on for more than 30 seconds! There is much on the packaging, and on the website, about these headphones being over-the-ear, with adjustability, etc. Yes they are fully adjustable - but however much you adjust them they still keep falling off! The first time I took these on a treadmill, I kid you not, they did not stay on my ears for one song. I gave them another go the next time I went to the gym - but still rubbish! And they're not exactly cheap, either... As if they could get any worse - the wires connecting the headphones to the lead inserting into the mp3 player is more akin to a hosepipe than anything else - i.e. you pull it out of the draw and somehow it's made 17 knots in itself and you have to pull them all apart! Sound quality is fine, and the fit is ok -but not great, mind. So if you weren't using them for sport, these might merit a 3-star rating. But the fact that they are geared SPECIFICALLY for sport, and don't work - don't even get close to working - means these flop to a 1-star. Sorry, but they're awful!
I purchased these headphones for use running and at the gym, the headphones are of a real quality being "Sennheiser" and what not, who are a well established audio provider who know their stuff. The sound and bass is perfect however the shape and idea of the headphones? That my friends is a hole new ball game... The fitting is almost perfect but a little loose on my ears, perhaps their too big / too small... Wither way, when i began running and training at the gym the headphones didn't really do much for me and kept moving around inside my ear causing discomfort and fell out on a few numerous occasions. I'm not saying for one minute these are not good headphones for you (the person reading this) but i am saying that for me, they were a waste of £40 and i can safely say they will be going on eBay, thanks for reading guys!
