• Test different audio content or playback apps.
• Turn off any special sound effects, equalizer settings, or audio enhancement features on your device.
• Move the earbuds closer to the connected device.
• Move away from areas with strong wireless interference.
• Clean the speaker openings.

Check whether the touch-control area is being affected by hair, hats, jewelry, fingers, sweat, moisture, dirt, incorrect positioning, or another connected device.

Open-ear earbuds are designed to keep you aware of your surroundings. However, in busy streets, strong wind, public transportation, or crowded offices, the microphones may still pick up some environmental noise.

• Make sure the microphones are directed toward your mouth.
• Keep hair, clothing, and jewelry away from the microphone openings.
• Move away from fans, air vents, and continuous noise sources.
• Make calls in a quieter environment whenever possible.

1. Position each earbud correctly on your ear.
2. Slowly rotate or move the earbud to find the most secure position.
3. Place the speaker close to and aligned with your ear canal, but do not push it into the ear canal.
4. Gently adjust the ear clip or connecting section so it follows the shape of your ear.
5. Gently shake your head to test the fit.

• Adjust the position of the earbuds to avoid sensitive areas of the ear cartilage or earlobe.
• Do not clamp the earbuds too tightly.
• Start with shorter listening sessions when using the earbuds for the first time.
• Remove the earbuds and allow your ears to rest before trying again.

Fit may be affected by the size of your outer ear, the position of your ear canal, and the overall shape of your ears. Follow the product’s wearing guide and adjust the position carefully.

This is normal for open-ear earbuds. Open-ear earbuds do not block the ear canal, allowing you to remain aware of traffic, coworkers, and other surrounding sounds while listening to music or taking calls.

Environmental noise can affect how loud open-ear earbuds sound, particularly on public transportation, airplanes, busy streets, or in large offices.

• Adjust the speaker position so it is closer to and aligned with your ear canal.
• Move to a quieter location.
• Increase the volume moderately.
• Avoid listening at maximum volume for extended periods.

Because of their open-ear design, some sound leakage may occur at higher volume levels or in very quiet environments.

• Lower the volume.
• Adjust the distance and direction between the speaker and your ear canal.
• Use a low or moderate volume in quiet offices or during private calls.

Actual battery life may vary depending on volume level, call duration, Bluetooth connection distance, wireless signal conditions, environmental temperature, features being used, and battery condition.
