Looking to connect a 2011 Samsung Plasma to a bluetooth/wireless speaker

Sep 26, 2018
The device i'm looking with has a serial of BN64-01939A-00

So my best friend's mother came to me asking for advice on hooking up a wireless speaker than she can hook to a chair as she's getting hard at hearing these days and is hoping that it will help her with hearing the tv. Would getting a bluetooth transmitter such as the one here https://bgr.com/2017/11/14/this-simple-device-lets-you-connect-your-tv-to-any-bluetooth-speakers-or-headphones/ be a good way to go?
