Ubixon Bluetooth headset with display

Ubixon is currently working on a next generation Bluetooth headset that comes with a display. This unique device’s display features high contrast indoors as well as outdoors without the help of a back light found on existing displays. There is no word on pricing or availability, but it is good to see progress in the field of Bluetooth headsets in different directions other than just shrinking it with each iteration. What other types of functions would you like to see in a Bluetooth headset that would greatly benefit users?
