Edifer G4 gaming headphones

My wife just bought herself new headphones for her online classes - the Edifer G4 gaming headphones. 

Really comfy and great sound, with retractable mics and virtual surround soundcard vibration. Great for gaming but not sure about online lectures.

Reminds me that I need a replacement for my old worn out Armaggeddon Molotov 5 budget gaming headset, which has seen better days. Any suggestions?
