Hi Rosie
I have an infrared device which I plug straight into my Cochlear Implant processors so I can't really help you with what you use. I do know that before my Cochlear Implants I used headsets over my hearing aid - at full volume. My husband could hear it in the kitchen even though it was coming through ear muffs and still I struggled to hear it.... I used to burn these out every few months because of the volume I played them at.
