I love these headphones. The reasons are as follows:

1. They have very good speakers and you can hear rich sound.
2. They can be connected simultaneously to the Xbox (series, one) and another Bluetooth device (mobile, tablet, computer, Nintendo Switch, etc.).
3. The microphone quality is very good.
4. It has the ability to auto mute when you're not speaking, so your friends won't hear annoying noises.
5. You can lift the microphone and "hide" it next to the headphones. This means you can wear them while on the metro/bus.
6. As soon as you open the headphones, the Xbox automatically turns on.
7. It supports Dolby Atmos, Windows Sonic, DTS:X (these can be activated by purchasing applications on Xbox/PC).

Notes:
1. When you open them, they won't have a battery, so you'll need to charge them for about 3 hours.
2. Make sure to do the firmware update through the Xbox (xbox accessories).
3. They don't have an audio jack, so be careful. Xbox Wireless (connection type) + Bluetooth is the only way to connect, it doesn't connect with any cables.

Negatives:
1. I find them somewhat heavy

After many hours of gaming on the Series X, and initially having negative feelings about these headphones, I reconsidered regarding the sound quality. With the proper equalizer settings through the Xbox Accessories application, Microsoft's headphones deliver excellent sound. The Dolby Sound & DTS X applications available in the store enhance the quality, as they are compatible with Dolby Atmos & DTS-X, despite being stereo. I have included photos with the settings I made for game mode, as the default game preset is very flat, with all frequencies in a straight line, making the sound quality undefined without color and emphasis on details. If you wish, try the settings I have made for the Series X console, which increase the treble and midrange, and decrease the bass significantly, as the bass in the initial settings is overpowering and drowns out all other sounds. I consider this setting to be quite good for games like BF 2042 and overall FPS games like Cod Warzone, etc., and it will satisfy you.

Don't do it to yourself. It drove me crazy.

I was looking for a wireless headset that could connect to both the XBOX series S and a computer for several weeks. Its price was 120-130 euros, but it dropped to 80 and with the reviews from Skroutz, I made the MISTAKE of buying it, as it seemed like an opportunity.

WARNING! Whatever I write below is ONLY for PC and NOT for XBOX, so you don't fall into the same trap as I did.

So, Microsoft advertises as a "feature" of this headset that with the lever on the left earphone, you can "play" with the volume of the game you're playing and with the voice chat program you're using (Discord, Teamspeak, etc). That is, if the game is too loud and you can't hear your friends, you turn it down a bit and leave it there. SURPRISE that awaited me from day one: I connect them via Bluetooth, play Youtube, Spotify, Discord. Very good and clear sound.

THE PROBLEM, however, is that as soon as I ran some games, as soon as the game sound started, the Discord / Youtube or whatever else I had in the background would stop or vice versa, I could hear Discord and Youtube normally but not the game, trying ALL possible settings. I did EVERYTHING in the Sound Settings to fix it, and the only thing that worked for everything to play was to disable the one function that makes the sound TERRIBLE. After many google searches, I found that this issue has been present in the community since 2021!!!! and without a solution. Many people have this problem, it's UNBELIEVABLE.

The funny thing is that I couldn't find this problem anywhere in all the reviews I looked at, apparently the only way to find it is to buy them and ONLY AFTER experiencing it, do a google search to find it and feel the bitterness :/

I also share my own review through XBOX Hellas.
Today we will talk about two models of Microsoft headphones.
After a year of using the wireless Xbox Wireless Headset from Microsoft, we decided to get their smaller sibling, the wired Xbox Stereo Headset.
At first, they seemed less quality, like they were lighter. But we were deceived due to the difference in weight from the batteries they don't have.
Their significant differences are:
* The wired ones are lighter because they don't have batteries.
* The wireless one has an additional Chat/Game audio balance dial on the left side. The wired one doesn't have it.
* The wireless one has a push on/off button with an indicator light for the microphone function. The wired one has an on/off switch without an indicator light.
* Also, the wired ones have the connection cable.
Other than that, they are exactly the same in terms of quality and sound characteristics that we tested.
Both support Windows Sonic, Dolby Atmos, and DTS Headphone:X on Xbox Series X|S and Xbox One, as stated by Microsoft, but we confirmed it by testing on Xbox Series X and Xbox One S. Here we should note that (for the wired ones, when connected to the Xbox GamePad) if you have made the necessary settings on your console, the sound comes out of the headphones with Windows Sonic, Dolby Atmos, and DTS Headphone:X. So, you don't need a TV with support for the above sound protocols.
The ear cushions are quite soft and don't press on you at all since they are Over-Ear, just like the headband cushion.
For the wired ones, they have also released a new anniversary edition for the 20 years of Xbox, called the 20th Anniversary Special Edition, but it has an additional cost of around €10.
Of course, they could have had the wired ones at a lower cost because by adding something extra, you get the wireless ones.
Overall, we were quite satisfied with both options, which we highly recommend for Microsoft fans.
Now you might say that for the same money, you can get something better. Yes, but everyone has their own preferences.

The headphones are amazing for what they offer for the price they ask. Awesome sound quality and very good bass, instant connectivity with the console as well as any other Bluetooth supported device. You can have 2 devices connected at the same time and listen, on the console and either pc-tablet-mobile etc.
The build quality is impeccable, the Volume -+ on the right headphone is everything since you no longer need to go into menus to adjust the volume if you had headphones that didn't have this feature before.
The battery surprised me, here I should note that they come from the factory with an empty battery, which means they need to be connected with a cable the first time, otherwise they won't turn on. Also, as soon as they are connected to the console, they will do a firmware update. I charged the headphones for 25 minutes, played for 4 hours and they still showed that they had power, they hadn't gone red. MS says that with half an hour of charging they give you 4 hours of gameplay, and with a full charge that takes about 3 hours, they give you 15 hours of uninterrupted gameplay. Flawless.
In terms of ergonomics and comfort, for my taste they are simply perfect and they don't tire me even after 5 hours of continuous gameplay.
Also, like every Xbox controller, when you press the central button, the console automatically turns on, so here there is this feature with the headphones as well. There is only one issue there, if you want to use it on a device other than the console and you go to turn it on, it will automatically turn on the console as well. For now, until they do a firmware update and put a power button for this feature, what you can do is unpair them, desynchronize them from the console before turning it off.
Honest and absolute value for the money for those looking for build quality, perfect connectivity, wireless connection, ergonomics and autonomy in a package for €99.
