This concept design comes to us straight from a Bluetooth Headset Design Contest where Matthias Lange created a practical alternative those dorky headsets we continue using. The device called the Clipset nxZEN clips on to your collar, and has a retractable ear bud so you can answer calls. To keep it simple, the clipset only has 3 buttons to control volume and answer incoming calls. Looks a little rough, but let's hope designers continue to create concepts to replace the current Bluetooth headsets.
