I came to choose the disco after looking around for a suitable docking system for my HTC Desire and failing to find anything that was not specifically designed for an iDevice. The Disco does not charge the phone but it does everything else really well. First of all sound quality is great, easily fills our lounge and kitchen on 1/3rd volume and the optional bass boost is effective and impressive.
Pairing with the phone was no problem and I have now got it paired with my laptop and PS3 (via a Voiis BT transmitter). The speaker goes into standby mode after switch-on but wakes up as soon as one of its recognised devices connects and starts playing music.
Build quality is nice, it has a weighty solid feel with a simple, slightly retro, appearance and comes with a sturdy padded case for transport.
