It's getting there. Starkey has a pretty good setup with the iPhone without needing a remote interface, but still trying to get it refined for Android as it still requires a remote (which is about the size of a business card and fits easily in your pocket). I demoed the remote for a couple of weeks with my Android phone, pretty amazing device, however it's not 100% perfect yet so I turned it back in rather than buying as it had some issues staying connected.
The Surflink Mobile 2 is what I demoed. Very cool in that you can have conversations through your hearing aids (acts as both receiver and microphone, so totally hands-free calling), but my favorite was streaming music through my hearing aids, could turn the phone on Pandora at work and have music going all day and anytime someone would talk the music would soften to where I could hear them. Very cool tool, but like I said it's not quite there yet as it had a little bit of connectivity issues.

Hearing aids today are almost like computers, as soon as you buy a pair they are almost immediately obsolete.
