So this is kinda terrible. I tried it out yesterday and today with different games. I hear a lot less than I do just plugging in regular headphones. I do NOT recommend.
Haha, I sold my Wii U last year, and I still have this headset, and it's my main PC headset right now... was so bad at first, but it's amazing how you can adjust to such poor quality, I ended up preferring these stupid things over my brothers $120 headset... I'll be keeping these for when I re-buy my Wii U.
