TestFreaks posted a review on the Sound ID 300 Bluetooth Headset

This past month SoundID has released the follow up to the SoundID 200, the aptly named SoundID 300. This Bluetooth headset features noise cancellation technology, volume compensation, automatic volume control and dual microphones. All these features and more are packed into a small form factor making the SoundID 300 an unobtrusive yet stylish alternative to bulkier cell phone headsets.
