The 7.1 Surround Sound isn't a huge selling point, even though Corsair is leaning on it heavily. Sometimes the added directionality is noticeable, but most of the time it sounds like a hollowed out stereo headset. In other words, it's headset surround sound — nothing more, nothing less, and definitely nothing revolutionary.
The microphone has a weird tape hiss sound in the background, but is otherwise pretty good at voice reproduction. The fact that you can flip up the boom mic to mute is ultra-convenient, and I don't know why Corsair didn't just include it on the H1500.
Wireless fidelity holds up to around 30 feet, though I started to notice some crackle around 20 feet. Walls obviously cut that range down considerably, with a single wall of my San Francisco apartment slicing the range down to 10-15 feet. Corsair also includes a 4-5 foot antenna you can plug into a USB slot and stretch away from your computer for a bit of extra range.
The battery lasts about ten hours, after which you're stuck wired into a USB port until the headset charges. Since the wireless dongle also takes up a USB slot, that's a total of two slots needed to use the H2100.
The H2100 isn't a fantastic wireless headset, but it is a cheap wireless headset. With other companies charging an exorbitant amount to go wire-free, I expect all my talk of sound quality and design and the like won't matter a bit if you're set on cutting the cord for a reasonable price. Corsair's one of the few offering a wireless option at this price, and you can see why — corners were obviously cut, especially in regards to the design.
But again, it's only $100. For a wireless headset. It's doubtful you'll find a better deal elsewhere.
