As someone with significant hearing loss, this extension works really well for me. I use it 75 of the time watching anything with headphones! Thanks Aliaksandr!!

The increased volume changes to default, wish it stays the same all the times as per user's adjustment.

can't complain for literally making my headphones useful though, thanks to the coders. :) God Bless You.

looking for a day to contribute for your efforts.

Very satisfied with the result
