I review the Sound Blaster Evo ZxR headphones.
Summary:
Sound quality: Okay, but bad for the price. Gets better with AptX enabled devices.
Build quality: Average, but bad for the price
Comfort: Good
Active Noise cancellation: Doesen't work. Just a gimmick.
NFC: Works
Virtual surround: Doesen't work over bluetooth, works fine otherwise.
Microphone: Okay, bad for the price.
Software: Works well, but stay away from virtual surround.
Verdict: An okay sounding headset that justifies its high price point with extra features that sadly don't work very well.
