Conclusion: The Sound ID 510 is moving closer to the perfect Bluetooth headset. It is feature rich, well designed and stylish. The Touch Sensor control is a welcome addition especially in a capacitive touch screen world. The on/off switch is another great addition and avoids the press and hold style of other Bluetooth headset models. The iPhone app is a welcome addition and can be even more useful as Sound ID incorporates new features.
Pros: Works with iPhone app, Volume control by touchpad, Excellent Sound Quality, Firmware upgradeable
Cons: Piano Black finish = fingerprints, Main Button push device into head when pressed, Some features inaccessible if not used with iPhone/Android/Blackberry based phone
