As expected - a bit disappointing FM

The product works perfectly with my Android Mobile Motorola Defy.
Perfect for listening to music while commuting (on my mobile via Deezer application), headphones isolate outside noise very well.
However, for a hands-free phone use, we hear from inside a bit like with Kiess balls ...
Otherwise the sound quality is quite good compared to the headphones included with the phone.

Small flat for FM radio function: The function is not very accessible to my mind and reception is not really good.

The integrated battery charge holds very well but you have to remember not to leave turn the unit on all night ... no sleep function clearly.
Namely that it comes with a micro USB power adapter: also handy for recharging a mobile android.
