At about £30 this ain't cheap but I was looking for something for my very deaf father. The 'phones plug into an external mic/amplifier combo (£5).This home made solution isn't elegant but it is effective. Old folk (esp with dementia) cannot deal with these super small "in ear" aids). They are fiddly, get lost, get broken and are not very comfortable if you wear glasses as well.This £35 combo replaced two micro devices costing £1300 and works really well. The headphones are reasonably robust and even if I have to replace in a few months - well there are a lot of 35's in 1300.
