Slide the power switch on and off several times
If the switch seems difficult to slide into the "ON" position, slide the switch on and off a few times to ease its out of box state.
Reset your headphones
If the headphones are unresponsive, you can reset them. Resetting the headphones resets the product controls and reboots the headphones. It doesn’t clear any device settings.
- Connect the small end of the USB cable into the USB-C port on the left earcup.
- Slide the Power/Bluetooth switch to the right. At the same time, connect the other end into a USB-A power source such as a computer or wall charger. When the reset is complete, the status light glows according to the current charge level.
Check the condition of the USB cable.
Inspect the USB cable for any signs of damage, including cuts, fraying, bent connectors, exposed wires, or excessive wear.
Damage to the cable can cause charging issues, audio interruptions, connectivity problems, or prevent the headset from being detected by your device.
If the USB plug or any part of the cable is damaged, replace the USB cable and test the connection again.
Note: If available, try a different compatible USB cable to determine whether the cable is causing the issue.
Try a different charger.
Use a different charger that is known to work properly and meets the product's power requirements. Connect the product to the alternate charger and allow it to charge for a few minutes. If the product begins charging normally, the original charger may be faulty and should be replaced.
