Product Q&A
Do these have surround sound
Do they work for Xbox one wireless controllers? I would use Apple earbuds with my PDP controller but that’s the reason why I need these because those controllers always break on me. Would it work on a Series X Controller?
I used this earphone on the Windows 10 PC, but the mic mute function is not working. Can you help?
