The earbuds are rated IPX4 water resistant. They are designed to be sweat and
weather resistant but aren't meant to be submerged under water.
The charging case is rated IPX1 water resistant. It's designed to be resistant to light
water exposure, such as light vertical rainfall, but isn't meant to be splashed
or submerged.
CAUTIONS:
• Do NOT swim or shower with the earbuds or case.
• Do NOT submerge the earbuds or case.
• Do NOT splash the case.
NOTES:
• To prevent corrosion, regularly clean the charging contacts on the earbuds with a
dry, soft cotton swab or equivalent.
• IPX4 and IPX1 aren't permanent conditions, and resistance might decrease as a
result of normal wear.
