Water Resistance (IPX5)
The Passau S223B speaker has an IPX5 waterproof rating, meaning it is protected against low-pressure water jets from any direction. This makes it suitable for use in environments where it might encounter splashes, rain, or gentle sprays, such as by the pool or during outdoor activities.
Important: While IPX5 rated, do not submerge the speaker in water or expose it to high-pressure water jets. Ensure the silicone cover for the charging and USB ports is securely closed before exposing the speaker to water.
