Bluetooth recognized by my iphone, my tablet Google Nexus 7, my PC and my laptop fixed. Very good sound, good bass. Power very satisfactory for us at home. Sober and elegant design. The buttons are located on the top of the unit, which is a bit annoying when you put the unit in height (! L is above a cupboard at home to 2m20). This is fine if the device is placed at waist height. Note: By applying this simple rule, I met no problem to use: press once on the left button to connect to the previous device. Press once long (3 seconds) to connect to any other device).
