3. Bluetooth-parring
- Sørg for, at dine hovedtelefoner er opladet.
- Power on the headphones. They should automatically enter pairing mode (indicated by a flashing LED light, typically blue).
- Gå til Bluetooth-indstillinger på din enhed (smartphone, tablet, computer), og aktiver Bluetooth.
- Select "JLab Flex Sport" from the list of available devices.
- Once connected, the LED indicator on the headphones will typically turn solid blue or off, depending on the model.
For optimal sound quality, some users recommend a "burn-in" period. Connect the headphones to a PC/laptop via Bluetooth, set the volume to low to medium, and let them play for 30 minutes to 1 hour without wearing them. A total of 30-40 hours of break-in time is suggested for best results.
