Well, I have them. Tiny little things, it is quite a relief to have actually made the decision . They are really comfortable and hardly visible at all.
I have not tried out the TV yet but I am hoping I can now watch without subtitles.
I did find the bus noises a bit disconcerting, and I never realise how loud my OH speaks.
Thank you for all the advice.
