My dad's having a hard time finding a pair of headphones that play loudly when connected to his tele. When he connects to his smartphone the audio playback is loud. Television is a Hisense 65A6GTUK.
The headphone jack volume is at 100% but it's not that. Over Bluetooth it's a nightmare, he's paying for years of work in the metal industry, his hearing isn't the best now but being honest I've given the headphones a try connected to the tele and it's very low in volume.
The headphones itself haven't got any volume adjusters.
Thanks to anyone able to help my old man out
