The handling is okay and quite simple, would be desirable, however, a clip so that the whole is not always slip and fall the handset from your ear. Although 3 different sized plastic plugs are supplied for different sized ears, but even the smallest are still too large for my ears and thus drop the in-ears while running from the such - which did not happen in headset with clip (at least I do not ).
Disturbing I also find that the cable is led upwards, because I really just sliding the phone in my pocket - the calls I need it not more fish out of his pocket, but the player may be from time to time still operated. ;-)
All in all, recommended.
