Kind of strange, but true. Taiwanese company Inter Brands have released some cool sunglasses equipped with a Bluetooth interface.
The stem of the sunglass houses the Bluetooth module, and with a wire, you plug the earpiece in your ear. Different models and colors are available.
The Bluetooth is version 1.2, and the rechargeable battery offers 5 hours of talking time and 100 hours of standby time. It'll recharge in 2 hours.
I don't think this would work very well on a motorcycle, since the wind noise would make it impossible to talk on your Bluetooth equipped mobile phone, but on the other hand, this could be interesting to listen to your GPS or iPod. Must be cool to listen to music via your sunglasses..
The only down side is that you wouldn't be able to listen to them on your motorcycle the moment it become dark...
No price or availability known as off yet..
