I know this might seem impossible but here goes
I would like a pair of headphones for my mum to put on her head and watch tv - That's all - no wifi, no attaching to her hearing aid - she will take that out.
Does such a thing exist and do they have them at Argos or on Amazon
The best I have tried are are Sennheiser HDR 170 from John Lewis and others. With the base unit plugged into the telly or radio headphone socket, you can wander all round the house and garden with perfect sound.
