In general, the headphones are good. I would say wonderful. The sensors are working. The microphone is good. But here's the problem: during a strong wind, I decided for the sake of experience to call my friend and ask if I could hear well. As a result, it turned out that instead of me, the noise of that same wind spoke to him, and he practically did not hear me. Therefore, it is better to speak indoors or when there is no wind. Headphones do not groan, do not buzz. And what about the battery? 40mAh - one earphone, 620mAh - case. The case is fully charged after 2 hours. 5 minutes of charging the earphone from the case is enough for 30 minutes. If you are an inveterate music lover, the charge will last for 2-3 days (including recharging the headphones from the case), but if you put them on just to show off in front of your friends with brand new 4-generation bads, then it will last for a week. Personally, I liked the headphones. But that doesn't mean you won't like them either. To each his own. Good luck.
