He can hear okay on the telephone and he can hear okay if you’re talking normally and you’re only a few feet away from him (as long as there’s no ambient noise). Across the room, no.

As a bonus, now my music is wonderful too. music on those tiny 5.1 speaker systems is like listening to 4 transistor radios to my ears, with a boom box add-on. But real speakers, man they sound good.
Good luck, nice of you to be so concerned.
