Via Treonauts I have discovered the Tooth Ferry made by Nite Ize. The Tooth Ferry, which is available from Treonauts, is a carrying case for your Bluetooth headset. I usually use my headset only in the car and therefore have no reason to own one of these. However, I find myself really wanting one of these simply because of the cool name.
Kudos to Nite Ize for the cool name. From the information available, it looks like it is compatible with a wide variety of headsets. If you regularly carry your headset around, you may want to check this out.
