Solved! Bluetooth pairing problem on JBL TUNE 600BTNC wireless on-ear headphones

Sep 21, 2021
This morning I noticed that the headphones are not connecting to my iphone. I unpaired them on the phone, but they still didn't show up. I did a troubleshotting steps by of pressing the "-" and "+" buttons, and also tried holding the power button for a few seconds. There is a power on and off sound, after holding the "+" and "-" buttons blue led starts to blink rapidly, however the headphones are still not found by either my iphone or my second android phone. I also not receive the sound of entering in the pairing mode. After launching it like usual the led right blinks two times, and loops like that.

Yesterday they were working well, nothing was done with them, they haven't been charged since then (today I charged them but after a problem occurred).

Thank you in advance for your help.
