Some models are waterproof or water resistant, with a specific IP rating (eg IPX7) indicating the level of protection. It is important to check the specifications before using them in a wet environment.
What does the IP rating I see on my Bluetooth speaker specs mean?
The IP (Ingress Protection) rating indicates the speaker's resistance to dust and water. For example, an IP67 rating means the speaker is dustproof and can be submerged in water up to 1 meter deep for 30 minutes.
