They are perfectly mobile even though they stick out a lot from your ears. However you won't even notice them that they are there. Easy to pair up and control but not loud enough. Good quality but a bit pricey.

I bought these headphones a few weeks ago for use in the gym. Initially I had problems trying to increase the sound but after research on the web, found that you have to make sharp short presses on the control button. The headphones stay in your ears pretty well, the blue tooth connect is not as easy as it shows in the instructions. Re-establishing the connection each time you use them seems to be the case ( I pair with Ipad 2 or itouch). All in all they are pretty reasonable value and with some minor improvements with the control, could be better value.

I bought this product two weeks ago and really like the way they fit in the ear and sound quality
