• Move away from fans, air vents, and continuous noise sources.
• Make calls in a quieter environment whenever possible.

• Start with shorter listening sessions when using the earbuds for the first time.

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.
