1) If the sound is somehow disappointing, kindly try checking the equalizer and application preset on your device. To set the equalizer- typically, for a mobile, it is - settings - music - equalizer. However, it depends on the brand of your device. Also, there are many equalizer apps available to download.
Additionally, please, mind the source - bitrates of the track could dramatically reduce the final sound quality.
2) Make sure the following conditions are met:
- Proper environment (no antennas, steel, a lot of other devices nearby)
- Clear path (no solid obstructions: walls, a lot of furniture, etc.)
- No other electronics on body (no walkie-talkies etc.)
- The headset is not running out of power.
3) If the issue persists, please
- Check the sound via both Bluetooth and LINE-IN mode
- Check the sound when ANC is ON and OFF (turn it on/off by moving the switch on the left earbud - LED is red when it is on).
NOTE: The source device should have aptX™ Low Latency as well, and the sound file should be HD - otherwise, aptX will never work properly(?).aptX™ Low Latency audio ensures your Bluetooth device can deliver sound in sync with visual media. It reduces delay and improves the end-to-end speed of the audio transmission.

3. Press and hold both VOLUME buttons at the same time for about 5 seconds in a Power On mode till you hear the "beep" sound twice and "Disconnected" voice prompt.
4. Turn off Z2 headphones.
5. While the headphones are turned off, go to your device's Bluetooth menu and delete "Treblab" from the list by clicking “forget this device.”
6. Turn your device's Bluetooth off and on. Treblab earphones will be deleted.
7. Turn ON your Z2 by long-pressing the POWER button for 3 seconds. You will hear the “Power on” sound clue. Then you will see the blue/red flashing indicating that the headphones are in Pairing mode.
8. Using your device, scan/search for available Bluetooth® devices. TREBLAB Z2 should be in the device list.
9. Select it. Once Z2 is successfully paired and connected, the LED will start flashing BLUE slowly.
