Great headphones, perfect for the gym. Poor service from i-headphones. I have beed overcharged for these headphones (£42.97) and despite numerous attempts to contact i-headphones they have not come back to me. I'd advise you purchase them elsewhere

The headphones fit brilliantly, have decent sound quality and are very comfortable. However the wire casing keeps splitting everywhere there is a repetative bend. Mine are now covered in insulating tape!

I was sceptical when I bought these, as all the other "sports" headphones I have tried have either fallen off or been very uncomfortable. However, the design of the MX75 really works. Once you figure out the correct size of inserts to attach these things really won't fall out, even when running long distances. They are surprisingly comfortable and the sound quality is superb for an in-ear headphone. And they really are sweat-proof!

Having scanned the great range of sports in ear headphones I purchased the MX 75 Sport, which arrived the following morning. That evening I set up the ear plugs and went for a run. Awesome! No more pushing ear plugs back into your ears, the sound was great as was the comfort. These are certainly a great choice for the money and are far better than the standard sponge style ipod headphones that just keep falling out no matter how hard you press them in.

I got these earphones a few months ago and i have found them to be amazing for running, and going to the gym i.e they never fall out. the sound is pretty good for earphones as well The only bad point is that it took a bit of time for my ears to get used to the pushing of the little things on top it took about 2 weeks.
