I have the same yet the Philips AS111 (4W) and the Designed for iPhone device DS3150 (all new to the market) ordered me to compare. By connecting Bluetooth everything worked, but me a loud noise noticed in particular, this machine here. The sound quality of the AS351 is simply bad: It shows no highs and mids. Even the little brother (AS111) with 4W sounds because of a lot better. It is as if here would be a dull haze on your device. Also, the device rolls over completely, is on the phone the volume turned up (mind you not full volume on the device itself), on all other devices this is not the case. The test using a 3.5mm cable brought out the same. Strangely, this one has yet mentioned in the reviews down from 3 stars. My favorite, however, is become the designed for Apple devices DS3150 (12W). Very nice sound when compared to the two versions of Android, there are clear highs and lows possible. Will get me for this device a Bluetooth adapter that I just sit up on the 30-pin adapter of the device.
