These 2 products from a company called Hybra are some of the most innovative designs I have seen in blue tooth design as of late. One is a wearable ring (called O.R.B.)which unfolds into a fully functional blue tooth headset. The other is a behind the neck eyeglass strap which functions as a phone headset or as music speakers!
They are slated to hit the market in 2nd quarter 2011. Pricing to start at $129 US.
