Battery care guide
Your earbuds come equipped with high-performance lithium-ion batteries and battery life span is affected by charging and usage. Follow the guidelines below to keep your batteries in great condition for as long possible.
Avoid using fast chargers if possible. Fast charging causes stress on the battery and will degrade it.
Avoid letting the battery drain completely or charging it when it’s already full. Try to keep the charge between 30% and 80%.
If the earbuds are stored for a long time, it’s recommended to charge the earbuds to about half-charge and then do a factory reset. Store the earbuds and case in a cool, dark, and dry place.
Avoid using or charging the earbuds in hot and unventilated places, 45°C/113°F and above.
Avoid charging the battery at low temperatures, below 10°C/50°F and using the earbuds below 0°C/32°F.
Avoid strong mechanical shocks such as dropping the earbuds or case on hard surfaces as it might harm the batteries.
