Hey Alan I just found this thread and I know you know your stuff about audio! What build would you recommend to hear footsteps better for fps games.. I only play cod and warzone on a ps4 soon a ps5 when I can get my hands on one! My budget is up too $1200 for a headset,modmic, and amp/dac. I read most of your post and it made me iffy on getting the AKG Pro Audio K712 PRO now. Any insight would be amazing! Thank you!
Hello! sorry for the late reply
Well that's a great budget you can do lots of things with it.
As ATLRoach mentioned PS supports most USB audio devices. Best path IMO is to get a Hi-Fi Headphone and Mic separately, like blue yeti, samson q2u, hypercast etc, however on PS can be troublesome.
When you connect a USB mic on a PS, PS is going to recognize it as a USB Audio Device, with Input (Mic) and Output (Mic headphone out), the mic headphone out has a DAC... very low quality is only made so you can monitor your voice, not good for gaming.
That's why mic with 3.5mm output (analog) is recommended, and a DAC amp with mic input.
I know I keep repeating... I swear not trying to sell it, but for practicality Mayflower ARC MK2 is a great all in one option, works with PS4/PS5 and you can use modmic on it. It can drive most headphones in the market.
Using a USB DAC/Amp like Mayflower ARC will allow you to play 4K/120Hz.
Headphones selection is a personal preference, but if you really want a footsteps detection overpowered ones, without breaking the bank... DT990 Pro's will be top of the list, any headphone with this features:
+ Great imaging
+ Great Midrange
+ Great soundstage
Will be great for gaming, miles better than you can find on gaming headsets.
So my best bet will be:
+ Mayflower ARC MK2
+ DT990 Pro or AKG 712 PRO, Focal Elex, HD560S, TYGR R300
+ Modmic or ATGM mics.
If you get AKG 712 PRO or whatever headphone and still have issues to hear foosteps (doubt it) we can give you an EQ to highlight those frequencies. 
Haha your good man! I really appreciate the response! Funny thing is I already bought everything and it's exactly what you listed! So perfect! I went with the dt990 pro limited edition 600ohms,mayflower arc 2,antlion wireless modmic. I Was going to go with the 250ohms but decided on 600 lol I hope that wasn't a mistake! I won't have everything til after the 23rd but I'll hop back on this thread and let you know how it goes!! And if you have any tips or tricks with the mayflower let me know! Thanks again alan!
