With a price tag of $90, the freshly-launched Corsair HS70 Wireless just became one of the least expensive brand-name wireless gaming headsets on the market. It's based on the wired HS50, so let's find out what was gained and lost after its wire got cut.

Is the hissing maybe due to a defective sample? I would've checked with Corsair to see if this is a known issue.

Apart from that, this headset is perfect for me. Corsair has literally cut out everything unnecessary (RGB, audio jack) to deliver a headset that just does what a headset needs to do. I remain unimpressed that they ask nearly double the price of the HS50 simply for the privilege of not being tethered to your PC, but apart from that, massive kudos to Corsair - bloody well done for answering the prayers of true PC enthusiasts who just want kit that works and don't want to pay out the wazoo for it.

No, I went through a grand total of three samples, just to make sure. I checked a couple of other HS70 Wireless reviews and nobody mentions the hissing, which only goes to show that it isn't easy to pick up (but it's definitely there). For a user that's not super sensitive to stuff like that, it isn't an issue at all. And even those that are will only be able to hear it occasionally, as any sounds, except the most quiet ones, mask it completely. When nothing's playing (no input is received by the headphones), the hiss isn't hearable at all, the HS70 Wireless is dead silent.

I was pretty sure you'd done due diligence (your reviews are awesomely thorough BTW), but it can't hurt to let Corsair know about the hissing if you haven't already done so. Since it's present in all your samples, it "sounds" like maybe a driver bug on their side.

As for the Corsair Utility Engine... all I'll say about it is that it's a 200+MB download that consumes much more disk space than that when installed, and all I currently use it for is disabling the RGB on my Void Wireless. If Corsair could cut down on its bloat, that would be swell. Their "replacement", iCUE, is even worse (search their forums to see what I mean).

Thank you for your kind words, I'm so happy to hear that you like my work!

Corsair was, of course, contacted regarding the issue :) Additional samples have been sent to me as a result of that. The final sample, the one that eventually became the retail one (that's the one I reviewed), was by far the best, to a point where I can comfortably recommend the HS70 Wireless to anyone looking for a wireless gaming headset that won't break the bank. I definitely wouldn't give the "Great Value" award to the first samples/iterations of this headset though :) It was a nice case of manufacturer listening to reviewer's feedback and improving the product accordingly before releasing it, instead of simply launching it regardless of everything. Kudos to Corsair for taking that approach, as far as I'm concerned.

As for CUE, I'm with you on that one. It's far too clunky for what it is. The features are there, but it's a pain in the butt to utilize them through the driver. The Void Pro lineup fares better in this regard, simply because its jog-dial allows you to use all of the features of the headset without having to open the CUE after the initial setup.

Yeah... for a refurb, and I don't buy used headsets for the same reason I don't buy used mice or keyboards.
They're not used, I have one. Typical "refurb" that's new.

I just received mine, they hiss when powered on for me mostly from the left cup, it's quite annoying. I'm hoping it's a defect and I can get it replaced, as they're otherwise "okay" for a wireless gaming headset. Bringing down the bass will decrease fatigue and increase clarity even without having to increase the EQ on the highs.
Also if your charger is of lesser quality you will hear the DC noise quite easily too in the left cup.
