Issue: Ear hooks do not pair with my device.

Solution:

• Ensure Bluetooth is enabled on your device.

• Forget "AZ15" from your device's Bluetooth list and try pairing again.
• Ensure the ear hooks are within the effective signal range (approx. 15 meters) of your device.
• Restart both your device and the ear hooks.

Issue: Only one ear hook has sound.

Solution:

• Ensure both ear hooks are properly connected to their respective IEMs.
• Place both ear hooks back into the charging case, close the lid, wait a few seconds, then take them out again to re-establish the connection between them.
• Check your device's audio settings to ensure balance is centered.
• Try re-pairing the ear hooks with your device.

Issue: Poor sound quality or unstable connection.

Solution:

• Ensure there are no obstructions between the ear hooks and your device.
• Move closer to your device to reduce interference.
• Check if other wireless devices are causing interference.
• Ensure your device supports Bluetooth 5.2 for optimal performance.
• Try switching between the different sound modes (Standard Music, Full Power) to see if it improves the audio.

10. User Tips

• Game Mode Persistence: Some users inquire about game mode staying active. The AZ15's mode selection is typically session-based. You may need to re-select your preferred mode (Game, Standard Music, Full Power) after reconnecting or powering on.
• IEM Compatibility: While the AZ15 supports B/C pin connectors, always verify the specific pin type of your in-ear monitors to ensure a secure and proper fit.
