Pure TV dialog for tired old ears - no more subtitles for me!

These sub $200 (Amazon) wireless headphones are amazing.  I have high frequency loss and fairly loud Tinnitus, so conversation can be challenging to follow.  Those movies without subtitles were especially frustrating.  For the past two months I've been in TV heaven.  The sound and comfort are outstanding.  
Some Roku remotes have headphone jacks. For those with Roku, buying a so-equipped remote and a budget earbud set, could save some bucks: (https://support.roku.com/article/115002930768-how-do-i-use-headphones-with-my-roku-enhanced-remote-f...)

I have the slighter bigger brother to these, the rs185 and can attest to their sq.
They truly surpassed my expectations in sq as I really bought them just for the wireless convenience.
Glad they are working out for you!
