After really easy pairing via NFC with my Nokia Lumia the small speakers are really neat gas. The sound really has a top sound quality, the bass is also very good for effect. The battery has been able to really every time to ensure stimulated 10 hours music, the app on Windows Phone also shows the remaining time on.
Even Android phones or the iPad can be used easily via Bluetooth, up to 10 devices can be connected to the speakers via Bluetooth. Nice gimmick: In the bottom lid still hides a blade connection for non-Bluetooth devices.
