Wouldn't you be better off with a soundbar? They usually have a Bluetooth subwoofer. You'll need to check what outputs your TV has looking for an optical one.

Possibly Ethan, but I had assumed they needed to be positioned right in front of the TV?. And while the better quality of sound may help my particular complaint, I'd rather get smaller (cheaper!) speakers near to me. I don't want to spend any more than absolutely necessary at the moment because I may not need these solutions once I get a new TV.

And thanks for that link Falkirk Bairn. I know I could have looked up on the computer, but sometimes easier to speak to someone who has actually done it themselves!.

For those of us of a certain age or if you have impaired hearing then it might be better as BT has in going the whole hog and having your own headphones. Unfortunately I have both characteristics and after a bout of Ramsay Hunt syndrome (I wont bore you with the detail, but it is very unpleasant) the hearing in my right ear was severely damaged. As ones hearing deteriorates typically the high notes go first and increasing the sound level as such may not sort the issue, in fact it can distort the sound more for the impaired listener I understand. More is not necessarily better.

I use an Avantree headset with a bluetooth transmitter. I think it cost me around £60. They are an American company but sell here in the UK and elsewhere as well. I believe you can buy just the transmitter and then hook it up to a speaker, but I am no expert. I do find that I increase/decrease the sound level when viewing but at least I can hear clearly. Also the family can listen at a level that suits them without being blasted out, my wife was forever complaining about the noise level when she entered the room.

I also have a ridiculously cheap pair of ear buds that I bought as an Amazon special, Beltone Bh-BT021 I believe, that I bought for about £12 one time. They are brilliant! I can watch TV/Youtube on a laptop/ipad without disturbing anybody else and they are great for travelling, working in the garden etc.

I am sure you can find similar on Amazon etc and maybe at a better price.
