Fantastic for their price in sound, just combine them with high res with a good dac adapter, if the mobile phone does not have a jack port. I comfortably use them on a computer but I have headphones. Sturdy construction, metallic, they don't tire, thick cable for headphone pests and braided! It also has a clip to hold the controller so it doesn't hang. Pretty good noise canceling. They ask me where I am when I go for a meeting because they don't believe that I have left home XD. Up to 100 euros max, they are on par with others in noise canceling. It's not worth paying more, for this feature alone, up to 100. After that, there are better options but for this price, it's a gem of a feature. This feature works well only with Xiaomi mobiles. You have to select these specific headphones in the settings to know. It works with others too, but not as well.

This particular model of headphones, as mentioned in other comments, is old. Also, as mentioned in some comments, the noise canceling doesn't work well, the difference with/without it is imperceptible! Otherwise, they work very well with Xiaomi phone, they have very good sound and they seem quite durable. Sometimes their wires get a little tangled, but it's not something that bothers me at least! I bought them for 17 euros, I wouldn't pay more!

The build quality is very good. What concerns me is that it was manufactured in 2018. Activating the ANR, I don't notice any difference! I don't know if it's defective because I don't have experience with this specific system (ANR). Overall, the sound is quite good.

The noise cancelling technology of these headphones is definitely not the best. Also, I haven't had them for very long and one earphone doesn't have the same volume as the other. Maybe it's because of my mishandling
