Question: how to pair both qcy bluetooth headphones?
Answer: Step 1: Power off two QCY T1 EarBuds and tap and hold MFBs on both of them for 20s (LED will blink red and white then turn off and 10s later blink red and white 3 times)
Step 2: Tape and hold two QCY T1 earbuds for 1s to power on（LED blinks red white twice) and two earbuds will auto pair with each other.
