Great for become mobile with it! Small and lightweight, it takes anywhere. Even by car, it can be used to replace a Bluetooth kit. The audio quality is correct but Bluetooth is not a miracle (not Apt-X codec) ... This is not a home theater but HP is doing very well with enough power for most uses. Used one or two times in speaker phone successfully. I do not have enough perspective on autonomy but promised 5 hours seem to be there. To be totally versatile it would need a jack input ... which is a few euros + (eg August.) Only a little troublesome points: - The tones in the startup and shutdown are at max volume - The short-term standby forcing to turn it off and on again to activate the Bluetooth - Activating the discovery mode to associate a Device BT: sometimes a bit laborious. In fact we must turn the HP, wait for the tone and immediately press the button for a few seconds. One might be disappointed by the absence of controls (volume, forward / back ...) but that's part of the minimalist concept: everything is controlled from the Bluetooth source - personal it does not bother me. In conclusion: to save space, move to music and if we did not need wired: I highly recommend this product.
