The Bose SoundLink Revolve+ (Series II) isn't fully waterproof, but it does have some water resistance. The manufacturer lists it as having an IP55 rating, which means it can handle some dust and low-pressure water jets from any direction.
So, it should be fine with splashes or light rain, but it’s not meant to be fully submerged in water or left in heavy rain for long periods.
From our research, folks have mentioned that the speaker works well in wet environments like by the pool or during a drizzle. Just don't take it for a swim or leave it out in a storm.
It's built to last with occasional water exposure, but it's not made for heavy rain or underwater use.
Also, just a heads-up: some people wish it had a USB-C port for charging instead of the micro USB it uses, since USB-C is more common and faster these days.
But overall, its sturdy design and great 360-degree sound make it a solid choice for most situations. Just be a bit careful around water to keep it in good shape.
