My BIG problem !! is both NHS and private - Boots- I can not understand the spoken word, not all, but many my system fails to cope with all the sound bits that go together in the speech prossing. weird. When I say ' pardon' the speaker ,repeats it louder, which only amplifies the problem What's to one done??? The mould in the NHS plastic riddled with channels that forever kept getting bunged up with ear wax, could never.never get them clean.Perhaps if money is no object Well !! I must have missed many a pint!!!!
