sorry to hear that, my pair has been flawless since day 1, it is a b-stock pair, however I heard that b-stock can be even better than new pairs because they have to do additional QC on those pairs to make sure they're actually working before reselling them :P

you may want to try that

155 is the only one that fits correctly for me i tried 100 145 W1 xelastec

another thing you can try is reversing the connector of the stock vari cable, the image is not too clear so i cant tell if you have the arrow pointing the two bars or not, for me it adds punch to the midbass when i dont align the arrow with the two bars

openbacked will help you hear your girlfriend when she needs you /copium

your brother needs to wash his hair lol 😆

i found a steelseries nova pro open box for 85$ on amazon, im using the dac without the headset lol this is mostly because xbox is very picky about the dac, but it works decently with ps5 too (both of my consoles are wired usb to the dac and it works flawlessly)

qudelix5k and use the app to give yourself a nice bass shelf :)
