I purchased the headset and the mic quality is terrible compared to all the reviews I've seen. The volume is low with the mic at 100%. I have to add 20 dB for them to sound loud enough but when I do, it sounds so bad. It adds a bunch of white noise/hissing on my mic. Any solution or is the mic just faulty? I don't have a sound card so it's connected to my motherboard which is an ASUS Prime B250M-A and it uses Realtek HD Audio. And yes, I've checked that the cable is pushed all the way in, and everything is connected properly. Thanks in advance for your help!
