Notes on the ingress protection rating of the earbuds
The earbuds feature an IP54 ingress protection rating which means
they are protected from the ingress of dust and water (according to
the International Protection Rating (IP code), IEC standard 60529,
tested under laboratory conditions).
The earbuds can be used at the beach in sandy/dusty conditions and
in rain, for example. However, they are not suitable for immersion in
water or for wearing in the shower. In case of permanent moisture/
wetness, the ingress protection can be reduced and the product can
be damaged.
Do not charge wet earbuds. Completely dry wet earbuds with a dry
cloth before charging them.
The charging case is not splash waterproof. Always keep the
charging case dry.
