Depth and quality of sound great_ and so portable for taking on holiday !

Fully came up to expectations. Don't understand how such small-powered speakers are capable of providing such a rich range of sounds. Only negative is in streaming music while at the same time working on-line with another web phone. There is a mild interference that disappears once competing smartphone closed down. Microphone for sending and receiving calls was an essential requirement and works well to provide high quality telecons on connected Bluetooth Smartphone. Also needed to have optional battery power. No static issues, with excellent clarity of sound. Not 100% happy with "handbag" design!

I bought this product a while ago. Everything works as it should, very portable. Batteries do not drain while using it plugged in.as soon as you unplug it it seamlessly switches to battery mode. It's suitable for small to medium sized rooms.
