@X-Genetic-X Not hard to understand why Apex has issues. The mixer is more complex than in most other games and there are also a ton of different sounds, so a lot more things that can either fail or distract you.
Unfortunately, there's no quick fix for the sound issues. audio bugs are very difficult to reproduce and solve in general. Simplifying the system is not an option, the experience would just become horrible.
Anyway, to be more on topic, I tried 3 different headsets, all with microphone turned off: Sony WH 1000 XM4, Bose QC35 and Audio Technica ATH M40X. The best experience is on the ATH M40x, which is not a surprise for me, as these headphones are balanced for studio monitoring, while the other 2 use all kinds of enhancement (bass boosts, active noise cancelling, etc.). Only problem with ATH M40x is that they are by far less comfortable than the noise cancelling ones.
