Gold Wireless Stereo Headset discount 20% on amazon.

I don't see a discount mark. I wanted some headphones for a while, but people say without dobly sound you are losing too much. Is that right?

They've been that price ($80) on Amazon for a while now (the OP's link was to the limited edition white ones, which are full price @ $100).

I've had a pair for a little less than a month now, with around 20 hours of use on them playing MLB the Show, Watch_Dogs, and the Destiny beta. For the price, they're great headphones - everything sounds really clear - bass, highs, and mid-range (I'm no audiophile but have spent a lot of time with headphones in the past 15 years of DJing), they're comfortable to wear for extended periods of time, and they're a snap to set up. The virtual 7.1 surround sound is good enough for gaming, too.

Even at $100, I would highly recommend these for gaming - especially if you have a S.O. and/or thin wills and don't want to disturb anyone late at night. 

i just got a black one... n thanks for comment, i use this for gaming in my PS4

I got black ones from newegg for $55 a while ago. While they may be worth $80 or more to some, I would wait for a better deal, unless you really need headphones or a headset. Like don't get me wrong I love them, but I also already had the original sony stereo headset so I waited for a real deal.
