Received a “KEF MUO Wireless Bluetooth Speaker” from Amazon for Christmas.
Specs : The frequency range is 60Hz to 20KHz, supports BlueTooth, NFC, has a 12-hour playback time and charging is via a Micro USB port.
The audio quality is so good that they make the Bose SoundLink II irrelevant. Bearing in mind their small size, they handle bass beautifully and the higher notes too.
You can even pair 2 speakers together for party mode.
