One of my users needs to have a handsfree solution, either induction loop or some sort of more traditional headset, that is compatible with his hearing aids and with his BB 7730.
Plantronics "says" that some of their headsets are t-coil hearing aid compatible, but there is NO documentation on their website that explains how. Supposedly, the M175, convertible headset that I have is t-coil compatible, but the user reported that it didn't seem to work. Barring some sort of documentation, it's hard to give more information to the user on how to make it work. Even went so far as to send a support request into Plantronics, but have yet to hear an answer.
Motorola makes a t-coil compatible induction loop, the SYN7875, that has a standard 2.5mm headset plug and doesn't appear to have any features that require a Motorola phone, but their support people couldn't tell me if the device works with any phone with a 2.5mm jack. They certainly couldn't tell me if it works with the BB7730.
At any rate, the user requires a headset that works with his hearing aids so that he can use the phone features of the Blackberry.
If anyone has any information about specific headsets that don't cost an arm and a leg, please let me know. Vendors, here's your chance to get some info out on your products and their compatibility with phones like the BB 7730.
From the research i've done, the information on a lot of the vendor sites in relation to this need is scant at best.
