I upgraded to these from a cheap pair of €25 (unknown brand) headphones and I am thrilled. The sound is really good for the average user. And if you want a more "wow" sound, you simply press the bass boost button and it becomes even better. Also, unlike many headphones, you feel like the sound is coming from somewhere close and not right next to your ear. This means they can be used for several hours without any problem since the design is quite comfortable.

As for the battery, I can't measure their exact lifespan, but they definitely last for a week and something with two or even three hours per day (plus the time I forget to turn them off!).

The way they fold is simply genius and makes them very compact despite being over-the-ear.

In terms of sound isolation, it's like entering a submarine, I couldn't ask for anything better especially on this budget.

The provided 3.5mm and USB Type-C cables look a bit fake due to their thickness, but they are perfectly fine.

The only thing I didn't like is the hands-free control. It has a lever that you press for pause/play, and you shake it right/left (momentarily) to change the volume. And to change the song, you hold the lever down for a while. The response, even for pause, is a bit slow and overall I don't find this system convenient. But it's probably a matter of getting used to it.

Overall, they are definitely worth it, if you don't mind the peculiar hands-free system, then there is nothing else to stop you from buying them.
