The headphones are terrible. I had similar over-ear headphones from Xiaomi, another model, and they were perfect. These specific ones are a cheap plastic that doesn't sit well on the neck when you wear them; the headphone cables come up high as if they are being pulled. Generally, all the materials feel fake. A waste of €30. It has an old USB port. Stay away

It is excellent. Very long battery life, quite good sound. Long lifespan. From use, the little wire that connects one earphone got cut. This is also the reason why I will buy it again.
