I am very happy with this purchase, I will advise everyone!

We had at our disposal: a Samsung Galaxy S7 Edge phone, an iPad 2022 9.7 and a computer with a Realtek sound card built into the motherboard. The same music participated in the tests - a playlist on Apple Music and several tracks in Flac format (for example, Queen, ATB, Modern Talking, Twenty One Pilots, Nickelback, Robert Miles). I connected it to the computer, the sound is not bad, the volume is enough to comfortably listen at the maximum (that is, in fact there is not enough volume, you always need a margin, since some tracks are quiet), but in some tracks at low octaves the soloist's voice was distorted into a robotic - not pulls out the built-in sound. I connected it to the phone, checked the same moment with distortion - there was no robovos, the volume level was about the same, but the sound itself became flatter - it also does not pull out the chip in the phone. But on the iPad, the headphones played well, the volume was more than enough, there was no robotic sound, and the sound itself became more voluminous and detailed. There is also an assumption that the iPad does not reveal the full potential of the headphones, you will need to check the work with external sound cards for PCs of different price ranges and compare it with the sound from the iPad - I will write in the comments when I come to the final conclusion.
Conclusion: if you are planning to purchase headphones for listening to music at home / in the studio and there is a good signal source (hi-fi player, home cinema, external sound with a good DAC, etc.) or are ready to buy it in addition, then these headphones will show themselves from the best side and give a lot of positive emotions.

Pros

- The sound quality is beyond praise. Clear surround sound over the entire frequency spectrum, nothing falls through, basses such as they should not hammer out of nowhere, but pump at the right moments, as intended. At the same time, nothing interrupts anything, all the instruments are heard, they can be distinguished and isolated from the context, including in the "meat" parts of the rock genre. You will hardly find the best sound in the budget up to 15-20k. - Soundproofing - good for passive, especially outgoing. If you do not turn it on to the maximum, others will not hear even in a quiet room. - Good build and components. The design inspires confidence, wiring, jack 3.5 plug, let's check the time. - The price, which is quite low for such sound quality.

Cons

- Cable 2/3 of which is wound like a telephone wire. As a result, it is quite heavy for a headphone cable, if you hold the tablet with all the cable on the weight, the upper part of the tablet is pulled down under the weight of the cable, you can feel it. - Stationarity - follows from the previous paragraph. Although the manufacturer hints at portability with a foldable design of the headphones and a bag for transportation in the kit - no, this is just for transportation, for example, from home to office / studio and back. It will not be very convenient to use them to listen to music in transport. - Demanding - you need a good enough signal source to reveal the sound quality of the headphones. (see comment)
