my headphones have started making a loud crackling noise that happens even when they are turned off. It's loud enough to be audible when they're not being worn. Is there anything that can be done?
When I try to charge the headphones, the LED blinks red quickly. I left the charger connected overnight, but the headphones did not charge up. I have looked at the suggestions on https://bit.ly/3blwbWY but they didn't help. Any ideas?
Are they compatible with a Samsung Galaxy S20 FE?
I can't register my earphones when I enter the SN. There is only one serial number printed on the white sticker but I get an error message saying enter the correct SN. How this issue can be resolved?
I am having trouble turning the headphones on. Instead of the usual tone a dual beep sounds when i try and turn them on. When charging the red light only stays on for about 15-20 seconds. Please help
Hi there. I have a question about the charge cord. It seems to be a different USB type. I can recharge because it doesn’t seem to fit properly in any USB charge/ connection port. Any help would be appreciated.
just bought mine yesterday, and I'm not sure if i am charging it correctly. should i turn it on first then connect my charger? because i am trying to charge it without turning it on and there's no light indicating it is charging.
How do you turn off the Tune 125BT wireless earbuds device?
