i'm not a true audiophile (maybe i'm an audiophilistine?) but having had the chance to give the index and its audio a good solid try lately i can say i'm supremely unimpressed
it might also be in part because of how much and how often i've heard that the index has audio that's the best thing since the invention of sex, but the whole concept of open-back headphones for vr seems wrong from the get-go
don't get me wrong, the audio sounds pretty good!
but i can also hear all my fans and base stations whirring with the index, which i cannot with closed-back headphones/other headsets, and i kinda want to be avoiding outside sounds when in vr?
it also has trouble making bass, i'm sure the frequency response being flat as it is means it's more accurate but that doesn't mean too much to me when the drivers just do not have the ability to power the sound into the snail that makes me hear
all in all, the audio is good and if you have an index you can expect good audio, but not to have full immersion and i would like for people to stop playing it up as the greatest thing
the microphone on the index is hands down amazing though compared to other headsets, gotta give it that
