Re: Firmware 4.5.2 QC35 ii
sorry to say but i've upgraded from 4.3.1 to 4.5.2 and had no issues either (2 units)... compared briefly to another on 3.8 and ANC is the same...
will compare more rigid next week...
I don't want to argue about that, but 4.3.1 don't have good ANC either, you just made my point. People are saying that the degradation started way before.
Anyway, or you just don't have parameters to compare or you got lucky and had no problems at all.
all i can say is that i do not hear a difference between 3.8 and 4.5.2 (but i'll do a more rigid comparison asap) (the 3.8 unit hasn't been upgraded nor downgraded)
and i do hear a clear difference between high low off
i guess i was lucky, but since the upgraded one was brand new i didn't had a risk cause i would have returned it in case ...
