Impressive sound quality for such a small size! Power well staged without saturation even listening volume maximum.J'ai tested with micro SD half-power which allows a music listening in the living room for example, very nice. The autonomy is about 5 to 6 hours observed in this case. A volume max or near-max and / or USB I see a life of about 3 hours. Charging time about 2h1 / 2. A reconnection, the volume remains the same level only when I turned off the camera so no surprise that volume shipment thoroughly upon restarting ... Very good! Only regret, no shuffle or opportunity to spend a listen to the next album to SD card or on USB.Il key must move forward one track, otherwise these choices work well using my smartphone. In summary, for traveling, hotel and camping, bathroom, workshop or ... Or you want this little cube is a great companion musical!
