2. Ear Tip Selection and Fit
Select the silicone ear tips that provide the most comfortable and secure fit for your ears. A proper fit is essential for optimal sound quality and call performance.

Low-Latency Gaming Mode
For a more immersive wireless experience for videos and games, activate the 60ms low-latency gaming mode. This reduces input latency for improved audio-visual response.
Charging
Place the earbuds back into their charging case to recharge. The case itself can be recharged using the provided USB-C cable. The earbuds last up to 15 hours on a full charge (including case recharges).
Maintenance
Cleaning
Regularly clean your earbuds and charging case with a soft, dry cloth. Remove ear tips and clean them separately with mild soap and water if necessary. Ensure all components are completely dry before reattaching ear tips or placing earbuds back in the case.
Water Resistance (IPX4)
The earbuds are IPX4 rated for water resistance, meaning they are protected against splashing water from any direction. This makes them suitable for active lifestyles and light rain. However, they are not designed for submersion in water or exposure to strong jets of water.
