Are the Quantum 400s wireless or wired?
Hi There, Are the cables used braided?
Is there any way we can order a spare USB-C cable or 3.5mm cable for the headset?
Can you make the colors change on the side of the headphones on ps4 and Xbox, or only on PC?
No sounds from Xbox whatsoever. Are these required to be plugged into a pc first and download a app to then be used on the Xbox? Instructions claim to plug straight into the controller and go and I have no sound.
Regarding the colors, if I put a certain pattern or color on them will it still play the correct color when connect to my Xbox or any other device that isn’t a PC?
Whats the difference other tha the rgb feature, between the 300-400. Ive read that the surround only works when connected through usb to a PC running the JBL software. When connected to 3.5mm it doesnt work? Is this true?
I can't seem to figure out how to get the microphone to work on my dell gaming laptop. The sound works fine just can't seem to figure it out I tried plugging in the usb type-c to type-a with the jack plugged in as well.
