Had these on my Wishlist for nearly 2 years now!
Now before anyone suggests cheaper alternatives let me remind you that these headphones are desired for their combination of sound, comfort, reliability & great inbuilt microphone!
The G4ME series are are set of gaming headphones produced from Sennheiser. They're basically tweaked PC360s.
Please note that these are stereo headsets that CAN also be used with your PS4, XBOX1 & MAC when combined with a headphone splitter cable.
The main difference between the G4ME ONE & G4ME ZERO is the ear cup material. The ONE's have velvet and the ZERO's have leather.
G4ME ONE
+Better airflow (cooler head)
+More natural audio quality (sound can leave the earcups easily)
-Sound leakage
-Hear ambient noise
-Velvet cups are more difficult to clean
G4ME ZERO
+Less leakage
+Less ambient noise
+Easy to wash earcups
-Less natural sound quality (depth, sound stage etc.)
-Sweaty ears
Another notable pair of headphones is the: Kingston HyperX Cloud II Gaming Headset Red
It's quality and abundance of features is respectable at that price point (includes 7.1 virtual surround sound & 2 types of earcups). $165 delivered.
Note: PC Case Gear offer the same price, but they have a dearer shipping cost ($16 vs $9.95). Although nicer website imo.
This is a pretty good bargain and you can take advantage of the $50 ebay voucher if you're eligible.

As for the headphones, I would rather spend a little bit more and get the Audio-Technica ATH-AG1. It has a far superior microphone, more sensitive and the speaker draws less power during playback. The G4ME has such a high headphone impedance and would probably have inferior audio quality without a good (+$100) amp.
Audio technica! That's my professional opinion!
Please don't down vote me. :(
