Fresh from the "why the hell didn't I think of that?" files comes a gadget that might do for hearing aids what Sean Connery did for toupees. Intended to streamline the path between audio augmentation and today's technology such as mobile phones and PMPs, the concept from Triagonale not only amplifies speech and ambient sound but offers an interface to music, cellphones and other sound sources.
Thing is, this isn't actually anything new. A company called ELI manufacture a small adaptor which adds Bluetooth to an existing hearing aid, giving 2.5 hours talktime and 140 hours standby, and it's already on the market.
