Weeeeellll, I'm really enjoying my JH5s, i'm really feeling the isolation. They've ruined me for all my other iems... and my grados.
I'm finding the fit a little odd... some days they feel too big, some days i feel like the seal is gonna break if i open my mouth just a little bit. it's bizarre, but the sound quality doesn't change so i'm not too fussed.
On the day which my JH5s are least comfortable, they're still more comfortable than my UE SF.5 pro, and they isolate better than any other IEM i've ever used.
worth it.
i've still got a whole week to decide whether i want a refit or not.... i definitely don't want to pay to get them refit further on.
i just can't decide. i don't want the fit to get worse, then not be able to reverse back to good enough.
