TV Audio Sender/Receiver

[DejaVu]

My nan is 92 years young and almost stone deaf.

She asked me see if I can sort out a way she can hear her TV in her bedroom without 'pissing off the neighbours'.

Usually, she's at max volume and can just about make it out. If a speaker was on her bedside drawers, it'd be far better for her.

Is the something we can plug into the headphone jack (it's an old TV) and Bluetooth the sound to a set of speakers closer to her dodgy ears?

I've searched, but not exactly sure of the name of the device I'm looking for.

Bluetooth 3.5mm jack sender/receiver speaker set!?
I dunno.
