I recommend this product
Average sound quality, excellent implementation
I like how easy it is to connect. I like that my wife can listen to the sound bar or tv and I can keep headphones. The sound quality is far from my Skull Candy brand with thunderous bass sound but using the balanced setting, bass does come up and very acceptable. There is very little to zero lag in the sound (you cannot hear echo between devices). I like these very much for the price and purpose. Comfort is good. I can wear these for multiple hours and movies/show episodes. From order to receipt was about 30 days to New York. I will purchase more headsets for either more users or for use in multiple rooms rather than move cables . I recommend this headset.

Quality
When I bought these headphones, I needed them specifically for movies. I talked to your support for a long time and they recommended these headphones to me. And I am disappointed in the sound quality. What 1D sound is there? The sound is worse than in the $ 10 headphones from Xiaomi. I have something to compare with, I have headphones for $ 10 and others for $ 800. But your headphones have the worst sound of those I have heard. Why do you write that they are designed for movies if you can sometimes hear small wheezing, the music sounds super terrible? No, I'm not picky, I let my wife listen to them and she did not believe that the sound was so bad. They connect instantly, this is good, they are comfortable on the head, but the sound is the worst in my life. I tried connecting via an optical cable, via HDMI arc and the result is the same. You can just hear the conversation well, but any other sounds are not very good. But the music is just awful. I don't know how it was possible to make such bad sound.

It has a great sound with soft pads. Love how you can block the noise around you. And the cinema sound is insane. I just love it.

installation et son
Très facile à installer et les différentes solutions de connexions sont claires et fonctionnelles. Le son 3D est vraiment très agréable à écouter et donne une densité et une forte présence
