Information

The waterproofness of the earphone body is compliant with IPX5.
IPX5 indicates that the product will continue functioning even if water is directly projected against it from any direction. While this standard guarantees this performance with fresh water or tap water at room temperature, it does not guarantee equivalent performance with warm water or seawater. In addition, malfunctions caused by water ingress due to incorrect handling are not covered by the warranty, even during the warranty period. The second digit of IPX refers to “Liquid ingress protection” according to JIS C 0920 (harmonized standard of IEC 60529), “Degrees of protection provided by enclosures (IP Code)”.
Do not use the earphones at high volume in a public place. Sound leakage from the earphones may be a nuisance to people around you.

Notice regarding use

For information on replaceable parts, such as eartips, consult your Yamaha dealer.
Your ears may tingle in geographical locations where the air is very dry. This is not a malfunction of the earphones, but is caused by static electricity on your body or a connected device
