It's great value for money and noise canceling is also great.

First of all, the treble and bass balance is good and I am really satisfied with the price. It is better than the cheap Qcy products even though it is a bit pricey.

I tried connecting to my phone more than 10 times, but it just won't connect. I ordered it and it was delivered 16 days later...ㅠㅠ (For reference, I have experience using more than 10 Bluetooth earphones) After 1-2 hours of practice, I was finally able to connect it after it appeared on the list of paired devices.ㅠㅠ It seems like there are a lot of device connection issues, so please take note~
