Delivery 2 weeks. At first glance, not bad headphones, match the description of the seller. It was important for me that there was a good battery. Yes, they work for a long time-8 hours of continuous listening, possibly longer. The sound is more like Mono, not very good in quality .. Extraneous noise is not poorly isolated, they connect to the phone and laptop, they sit well in the ears (in a small ear), the lights are bright. The buttons are small, you need to adapt, but working. On the box, in 3 days of active use, the battery dropped from 100% to 77%. Included type C cable, silicone cushions, instructions, everything was well packed and sealed with plastic. In general I am satisfied with the purchase.
Surprised me the quality of the headphones! I have used other famous brands, but these are infinitely better. The battery of the headphones lasts a long time and the battery of the case allows various recharges. The quality of the bass is a differential and the microphone captures clean sounds and no noise, I strongly recommend the purchase.
