Hi I agree with what Colin has outlined I too have 'profound' hearing loss, but that sounds worse than it is As a young man I had access to a low frequency generator and made a sound rig and a friend and I tested each other. We could both hear the extreme high frequencies 21Khtz now my cut off is below 4 Khtz.
I have found that NHS latest hearing aids compensate very well. I can often hear conversations at a long distance but when close up with a 'party' background it all becomes a jumble of sound.
Do not under-estimate the NHS hearing aids, although visible behind the ears I can switch off the rear microphone, tune into an audio ring in a room and also select partial local hearing for cmpanions to talk to you. THey are set up by a computer controlled device which has headphones and tests your hearing and records the result.
Then your own hearing aids are plugged in and the computer downloads the amplifier settings. Then the hearing aids are put back in the ear and simple tests carried out like low speach behind you and then there is a bit of fine tuning to suit you. The operator then goes through the available programmes, choosing your options, like volume control etc. What I select on one uses WiFi to set the same condition on the other.
I often fly long haul and the on ear head phones are fine as the ambient noise levels are low (beware lots of air noise in the so called 'Dreamliner').
I have been using bluetooth over ear headphones without my hearing aids and they work very well with my TV it does block out exterior sounds though. My TV switches the sound from speakers to headphone when the jack plug is inserted and although bluetooth is in the TV my 49 inch set is bottom of the pile and has it by-passed.
I have Virgin cable TV etc and the Virgin set top box has an audio output independent of the TV and I use this via a bluetooth Tx. It means I can also tune the Virgin box to a news channel turn off the TV and listen in bed to the news as I never turn the Virgin box off.
By the way if you do a search for how a modern camera works and how the image is created you are going to be in for a surprise, like they say "It is not what you think".

Roy
