Pros: Easy to use Great call quality
Cons: None

I have to say I love my 320. It was very easy to pair with Sanyo Katana. The 320's single button controls are a breeze to use (Better than most on the market today). The call quality is superb, maybe even better than the handset. The 320 is also very comfortable to wear for longer periods of time. Overall I would recommend this to anyone wanting an easy to use Bluetooth headset.
