Headphones all sound to one ear?

Are any of the of the OTE able to be single ear headphones? My husband has lost his hearing 6 years ago and needs single sided. We were trying to move all the sound to my headphones to give it a try and I just decided to ask here.

Don’t think there is just a single sided headset. With either 2 or one earcup the sound should be the same. There are probably more office type headsets that may have just one earcup.

I’d suggest moving the solution into the host, so say phone, make it mono in settings then turn right balance down?
