Strong and good sounding bass
They are quite comfortable for how heavy they are
The sound quality overall was quite good (with ANC on, the sound quality seems to be better - try it, who knows)
2 audio channels between which you can smoothly switch (for example, press discord while listening to music or vice versa)
TalkThrough function (but it reduces the sound from the main source to about 10% without the possibility to add volume)
Weak ANC which also stopped working after a few days (after a short googling I found many threads with this problem, it's probably a common problem, watch out for it)
Cannot be used while charging
Poor sound quality from the microphone (probably OK for gaming)
A little problem with the initial pairing with PC
7.1 is completely wrong
The noise after every signal drop is really annoying especially when I am on the border of the signal range
They are difficult
With TalkThrough, the volume of the main audio source is reduced to almost minimum without the ability to add volume
Endurance - if they could be charged while in use it wouldn't be such a problem
The quality of the sound output is different when you use the ANC function and when you don't use it (when ANC is on, the quality is better (but ANC stopped working after a few days))

Good sound
They don't last. The parameters say 14 hours and it doesn't last 4 hours
When charging, they shut down and cannot be operated
The price/performance ratio really does not correspond, strongly do not recommend

Comfortable to wear
They have lasted less than a year and one earpiece no longer works
Battery life is pretty pathetic
I would expect more from such expensive headphones
When charging, you cannot use
I definitely wouldn't consider them gaming headphones

If you don't have it for PC gaming (which is better served by a gaming wire), don't buy this. Hardware-wise it's a good piece, but connectivity is lousy and the battery sucks. I'm coming back.
Quite good sound
You can combine sound from 2 devices (1 dongle, 2 BT)
Comfortable, soft muesli, does not press on the head.
You can't charge and listen at the same time, as soon as you plug in the cable and start charging, the headphones turn off.
The dongle and firmware were updated with a cable other than the supplied one. Otherwise it says "failed" and no details.
Whoever wrote the PC app was a real tragedy. It crashes every hour, almost nothing can be set in it, and reading white text on a red background is a punishment.
The endurance is more than tragic. 6 hours max and no more.
After 10 minutes, when nothing is playing, the headphones turn off. Regardless of whether it is connected to BT or dongle.
No sound indication that the microphone is on/off.
The device does not connect itself via BT, even though it is paired. I have not had this problem with other BT headphones.
The volume control on the headphones only works via donglex when connected to BT no. And it's not a bug, it's a "feature" described in the manual.

The first time I used them, I was very surprised how much bass I could hear in them. So much so that it made me uncomfortable and I wanted to return them just because of that. I thought I'd give them a try and maybe it's just that I haven't had headphones that can do bass until now and that I'm just not used to them. When using it a few days after purchase, I started having a problem with the sound. The bass seemed normal to me now, but I had to have everything full everywhere to hear it at normal volume. 100% in the settings at the bottom of the bar, 100% on both YouTube and Netflix, and 100% directly on the headphones. On the ninth day after the purchase, my friend and I, who understands these technical things unlike me, tried to solve these problems with the appropriate program, but when I connected to Discord, my microphone did not work. The downloaded program didn't see the headphones at all no matter what we did. And even though we set everything as written in the manual, nothing was fixed either. I expected that if I paid extra I would get quality headphones. Instead, I bought the worst headphones ever. What's the point of headphones that look good but don't work at all and are so expensive? I returned the headphones today. The idea of claiming them and being given equally expensive rubbish for them was too stressful.
Beautiful design
Nice nice nice cables
The sound is solid (at least at the beginning), I just haven't tested it in games but on songs, so I don't know if the surround sound worked.
After a couple of days, the volume control does not work well. see larger description
After nine days, the microphone completely stopped working.
The headset doesn't want to communicate with the software at all.
Even when I have everything set up as written in the manual, they just don't work as they should.
The headphones are very uncomfortable on my head after putting them on, let alone when I wear them for an hour or two. And I have a small head.
These headphones aren't even worth it if someone gave them to me for free, let alone when they're 5200, -

Luxury sound and hearing aid capabilities
Don't be fooled by the other comments. It's all about the right settings and the capabilities of the computer.
Easy to use, support detailed settings for the demanding.
Live can run two different sounds over each other, from different devices at the same time.

quality workmanship
lovely design
rgb
microphone
Bluetooth
The headset doesn't want to communicate with the software at all, the software is also terrible, cluttered and broken.
The headphones almost every time I turn them off and back on, they either go out of tune or don't even connect.
In my opinion, these defects should not happen with headphones for 5 000CZK.
The headphones have terrible sound, the 7.1 sound doesn't work, once something is in play behind you you can't hear it or you can hear it really little.
cannot be charged and used at the same time
