I compared both 75t and 85t before i decided to go for 85t
Music quality: 85t imo is much better
I tested a few songs
1) “The way I are”.. the various levels of Bass were very clear for 85t even at max vol. on 75t will start to “crack” around 70/80% vol.
This could be due to 85t larger drivers.
85t 12mm vs 75t 6mm
2) “Straight, no chaser” & “Moonlight in Vermont”... the separation of the various instruments were better and clearer on 85t as compared to 75t
Call quality: the clear winner is 85t
I tested various mode of phone calls and data calls in a noisy shopping mall...
Whether its regular phone call, wifi call, Whatsapp call, LINE call, facetime, the audio quality on 85t is way better and clearer
3) ANC
personally 85T is winner
But i still need to put it through a series of real life testing
