Pregnant bought for my music in my travels, the product is finished, simple to pair. It is used with PC win7, tab2 Galaxy, Xperia Z, Iphone 4S and iPad 2. The sound is good until the penultimate volume level, can be a bit overloaded bass at full volume it saturates a bit if there is too much bass. The noise level is more than enough for a bedroom, bathroom or living room of reasonable size. It is légéremment higher when a cable is used Aux. Use hands free phone is good, the sound is good and the microphone works very well (my interlocutors do not see significant differences between the hands-free microphone and telephone) The battery life is good, about 15h bluetooth with volume 3/4. I suggest strongly that product for those looking for a backup solution listen to their music everywhere simply.
