I don't know about good hearing but very little loss yet. Probably too many rock concerts and loud car audio systems in my youth didn't help much either. I did find that blocking the high/mid chamber just halfway in high section of does help a bit. You can block the entire higher register section since the tips do contain a plastic channel but it's a it like blocking a tweeter with foam. It's gonna tame the highs but you definitely lose clarity. I'm stick experimenting with it some but so far it helped somewhat without muffling the sound. The answer was be a smaller amount over the entire highs/mids section. We shall see... It does make me curious to how the BA10s sound and while I do love the metal construction, they don't fit me that well included the ZS6. They always end up unseating. The ZSAs are the one the few metal ones that fit nicely. I guess we'll have to wait for more reviews on the BA10s.
BA10 fits like a big ZSA. If you're fine with those, chances are the BA10 will be okay too.
