My friend got ITE aids from NHS but only coz her ears are holes only as she has no ears.I've never known anyone who has been given ITEs on the NHS either. I know a few people who have small BTEs with thin tubing, but they only have a mild hearing loss. My guess is that you'd be better off with standard BTEs, with ear moulds, for your loss. As you are at university they have the advantage of having direct audio input for use with fm systems, as well as a t-coil and directional microphones. I have a severe loss and use super power BTEs which have power in reserve should my hearing get worse, which is always worth having. ITEs are unlikely to have anything in reserve.
