I could not be more disappointed with this product.
The Y adapter doesn't work, it simply doesn't recognize headphones. I've tried using four different headphones, plugged into three different devices, it's not the equipment I'm using, the thing just doesn't work.
The mic fine I guess, but you'll get a much better deal out of buying literally ANY gaming headset. I've had 20 headphone/mic combos with better audio quality.
