TLDR: Very good sound quality, good microphone (without noise suppression), huge battery, and incredibly comfortable. Very good build quality, and of course, Corsair warranty.

I have had these headphones for about a year. I come from VOID PRO USB (not the Elite).
The headphones are not noise-canceling, of course, they reduce external noise slightly since they are over-ear, not too much though since the earpads are soft and breathable. So, with this and the fact that the head support is very well made (and not too heavy), I have to say that they are one of the most comfortable headphones I have used. The sound is also very good, full ranges (low-high and mids) and satisfactory levels.

Finally, I want to comment on the microphone. As I said, I come from the VOID which had a pretty good mic but also incredibly good sound suppression, I could be on a call and watching a movie and the people on the call wouldn't hear anything, the same when someone entered the room and spoke to me, I could only hear myself. Now, the HS80 has a VERY good microphone quality, but it doesn't have the slightest noise suppression. In calls, everyone hears me clearly but they also hear my surroundings clearly.

Friendly tip: Download Corsair ICUE for the first time to do a firmware update (if available) and pairing, and the next step after connecting the headphones is to uninstall it. Trust me

NEGATIVES:
After 1 year of use, I have had to change both ear cushions because they came off (even though it was very difficult to find the original ones again, I paid 30 euros). Also, the entire top part (hard plastic) has broken in three different places because sometimes I put them on and take them off hastily. Unacceptable for such a company and such an expensive product. Now I am researching for the next purchase after a year of use.

POSITIVES:
They are aesthetically pleasing with a more minimal design without too much RGB, etc. They have good sound quality for both music and gaming depending on the settings you make. The battery generally lasts and they have very good connectivity as well as good software.

COMING BACK AFTER 2 YEARS:
Guys, do not buy them, you will waste your money! Never again Corsair! Many problems with Corsair's software, the headphones, even though I take care of the part that rests on the head that connects the two headphones, has cracked in 10 places and the microphone stopped working, which I do not know if it is the fault of the headphones or the software update.

Quite a good headset, with a very good microphone. Their sound is quite good and the free Dolby Access provided for the headset helps in supported games. The battery lasts about 12+ hours (with RGB off) and slightly less with the microphone on. The maximum distance from the transmitter is about 6 meters. However, for those who use Linux, I must mention that they do not work properly in Linux. In Linux, the sidetone is constantly enabled and functions as an audio channel. To turn it off, you need to set the volume of the channel to 0 through alsamixer, but every time you change the volume from the wheel, it resets the sidetone to its initial level. Also, they start with the right channel louder than the left, and you need to increase the volume with the wheel to 100% and a little more so that both channels balance, and then lower it to the desired level (this issue was resolved on its own after 1-2 boots). Finally, it uses some strange protocol, and tools like HeadsetControl have not been able to reverse engineer it.
I am satisfied with the headset, but 150€ is a bit too much. If you find it for <=120€, I would say go for it.

7 months of use..

I had bought them for 132 euros, at that time my previous headphones had broken and I needed new ones immediately.

The connection is simple with the Bluetooth USB it has, and you can connect them to a PC/Playstation/Xbox. The only negative is that the signal is lost at about 4 meters, but it quickly returns when it is within range.

In terms of comfort, it depends on the shape of each person's head, but even with my small head, they fit well.

The battery lasts from early morning until late at night with continuous use, but at that time you will need to charge it. You can use them while charging, and it makes a sound when the battery is low, but there is no warning when it is about to shut down.

There are differences between wireless and wired, but they are difficult to notice.

The microphone is the best one available with the Virtuoso wireless headset. It doesn't have built-in cancellation, so your keyboard sound will be audible, but Corsair has integrated Nvidia Broadcast into its app, and you can activate its noise cancellation from there (personally, I separately use Nvidia Broadcast from the Nvidia website because the built-in one in the headphones often didn't work even when it was activated). Plus, what you hear with the headphones doesn't pass through to the microphone for others to hear.

For me, the 3D sound is good. I haven't tried other 3D headphones to have a better opinion.

The ear cushions are the best for summer. The ear doesn't sweat, and if they wear out, you can replace them. It's not mentioned anywhere, but they are removable.

1.

After years with Razer headphones and coming from the Kraken 7.1 USB Mercury V2 model, I decided to switch to wireless and I was torn between the Logitech G733. My mistake was not checking if they support 7.1, assuming it would be obvious since I had an older model of headphones. But again, it was my mistake for not double-checking. In the end, after receiving and opening them, everything is fine, nice packaging, the build quality is very good, and they are lightweight on the head. After a while, it feels like you're not wearing headphones at all. The sound is good for songs, etc., and with Dolby Atmos, it adds another dimension. Now, as for gaming, specifically FPS games like PUBG, with the 7.1, I could tell where the opponent was, which house door they opened, as everything goes in a circle. Here, since it doesn't have 7.1, you have to settle for left and right only, and the sound is much drier, lacking depth, bass, and nice sound, no matter how much I adjusted the EQ settings. I just managed to fix it a little bit. And now I'm using my old headphones again. I'm afraid to try something else, even Logitech, because I don't know if it's a wireless issue, if they won't have the same sound quality as wired ones, and in general, I don't want to make the same mistake again with my purchase.

Very good headphones, comfortable and relaxing.
The microphone is excellent.
The cushions can be replaced if they get damaged in the future.
Although they seem quite durable and I believe they will last.
They work perfectly at a distance of 7-8 meters with a wall in between.
Superb build quality.
Their battery life is quite good, especially if you deactivate the RGB because with the RGB active, you lose about 1/3 of the autonomy.
In general, they last at least 8 hours at work with full microphone usage + 2 hours of gaming before I have to charge them again, and they definitely have more to offer.

There are 3 negatives overall, but they don't affect my decision to give them a 5-star rating.

-I would like to be able to customize the two buttons on the headset. For example, I would like to set the on/off button to mute the microphone so that I don't have to adjust it. Anyway, pressing that button alone doesn't do anything.
Perhaps in the future, they will provide this option with the ique.
-They are quite uncomfortable when I use them with their cable instead of wirelessly, especially when I want to use them while charging. The cable is rigid, especially in the area where it connects to the headphones, and it bothers me when I make movements while wearing them. But okay, I didn't buy them for their wired function, so it doesn't bother me that much, but I have to be mindful to always keep them charged.
-The battery level indicator on the ique has 3 levels, high/medium/low. I would prefer it to be displayed in percentages for more accuracy.

However, I am very satisfied with what I paid for them, they have exceeded my expectations.

I made the purchase with a Christmas discount at €80. It is the best gaming headset and they are fully worth the money.

Very comfortable on the head and ears, with no discomfort or fatigue. The construction is absolutely sturdy compared to other gaming headsets.

They work just as well wired as they do wirelessly. I would say the wireless mode has a satisfactory range.

The sound at first is very flat. However, there are many videos on YouTube for EQ adjustment that improve it incredibly. And of course, the microphone is by far the absolute difference in wireless gaming headsets. Specifically, my friends have said that I sound like I'm talking from my mobile phone.

UPDATE
Unfortunately, in the last year I have been facing issues, not due to the headphones, but due to Corsair's iCUE with Windows 11. Generally, the updates that are made by Windows cause compatibility issues and ruin the EQ, making the sound shallow again as it is with the default settings. And it seems there is a significant delay in resolution from both Corsair and Microsoft. So I would suggest keeping this specific issue in mind if you are interested in purchasing.
