I thought I would pass along that I purchased a Motorola H500 Bluetooth Handsfree Headset ($25 at Best Buy) for use while wearing my Widex Inteo CIC hearing aids. To my knowledge, the Widex Inteo CIC does not have a T-coil.

At least on my ear, the speaker of the headset does not touch the hearing aid, and there is no feedback. Sound quality is very good.
