LoriMDoes the PC37X work for console gaming (PS4, Xbox One, etc.) or mobile or mac?
Yes, however, you will need an adapter or a separate cable. The included cable ends in two jacks (headphone & microphone) whereas most consoles/phones have one port that takes a TRRS (4 pole) AHJ/CTIA standard 3.5mm jack.
If you want an adapter, something similar to this one (*2) should work.
