My hearing is duff but my wife's is acute. She can watch TV at a sound level I can barely hear.
So I use a pair of Sony MDR-7506 headphones plugged into an aging Sony receiver - STR-DA1200ES. The receiver is wired into our old Sony Bravia KLV-46S200A, which will soon need to be replaced.
So I'm considering wireless headphones.
I'd also like to dump the Sony receiver, but I'm not sure I'll get adequate volume from wireless headphones without another receiver or amplifier.
Advice would be appreciated.
