It works well with my phone, the sound is good (not mind blowing but is good) and the hat fits well in my head.
The battery is not that good is only around 3 hours of performance
The only real problem that i had was the charging port, it didn't work (the hat didn't charge because the port was loose) . I had to search someone to fix it.
I hope that the manufacturer fix that issue in the product, otherwise the product works very well
The hat includes a little usb cable for charging (the port of the hat is microusb like many phone ports) and the manual
