Sound was fine, but none of my calls could hear me. They said it sounded like I was talking to them from another room. Returned the product immediately.

It's okay.  The camera works well, but,  the microphone quit working and I use a USB headset with a microphone to be able to talk to others.

I didn't use it for a long time after purchase because I had no need, when I Did try to use it, the speaker worked but not the mic. It was too late to return it so I'm stuck with a defective piece.

Sound quality for this price range is awesome however, the mic doesn't work properly. I'm returning this pair and getting another one to see how they work..

UPDATE: Got a different pair, same issue. I guess this brand is not reliable at all.

Im having a serious issue with these. The sound is ridiculously low and won't go any higher, Ive looked at the systems device audio settings as well and its up all the way. Also the audio is lagging (i.e cutting in and out) and the mic does the same according to the people Im playing with. Everything is plugged right but Im having major issues with sound. Id really love for these to work.

I wanted to use primary for hands free answering phone, I could hear well but the other party cannot hear at all.  The mic is not walking.

I can't get the mic to work.  Beyond that the earphones are good.  I was specifically looking for headphones with a mic though and so I am a disappointed.

i have had so many issues witht he setup and to date cannot use the mic.  Maybe because i am on Windows 7 - i don't know!

not working fine on my computer (win 7). The microphone is somewhat too quiet. If I turn everything high, it becomes noisy.

Sound is fine but the microphone doesn't work.  When I use it on my phone , I can hear the other person but they cant hear me at all.

The head phones themself work fine but the mic hasn't worked at all upon arrival. I know its a problem with the mic and not something else because ive done a couple weeks of trouble shooting now from controller software updates and restarting to making sure the correct ports were open on my router and an open NAT type. The mic was broken upon arrival. This is on X Box One

Everything works great on this controller except for the audio input. Im not able to use any headphones or a microphone. The audio works intermittently it. I have to unplug and plug the cable back in constantly to get it to work.

Sounds great but every time I use the mic for phone calls then go back to music one of the right channel quits working. It's not the computer.

Might need to update or remove your laptop's Realtek audio driver for the mic to show up as a selectable device in Windows Control Panel or Sounds Settings.

Sound is OK, but nothing I do will get the mic to work, none of their drivers will detect their own headset.
