FAQ 1: Why the headphone has been fully charged, but it cannot be powered on?
-Firstly, you can use the 3.5mm cable to try if the headphone can be used in the wired mode.

FAQ 2: Why can't active noise reduction headphones completely isolate noise?

The high-frequency noise has the characteristics of fast transmission and attenuation. Active noise cancelling headphones does not have enough response time to capture and process them.
FAQ 3: Why is it uncomfortable to wear it for the first time?
