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.
CAUTIONS:
• Do NOT swim or shower with the earbuds.
• Do NOT submerge the earbuds.
NOTES:
• To prevent corrosion, regularly clean the charging contacts on the earbuds with a
dry, soft cotton swab or equivalent.
• IPX4 isn't a permanent condition, and resistance might decrease as a result of
normal wear.
