Dust resistance rating

Thanks to its IP67 rating, the Wonderboom 4 is sealed against dust as well as water, so owners can confidently use it at the beach or on dusty trails without worrying about grit and debris damaging the speaker.

Full IP68 dust sealing and a rugged enclosure allow the Charge 6 to handle grit, sand and other outdoor hazards comfortably, reinforcing its role as a tough, go-anywhere portable speaker for beaches, cottages and backyard use.

With an IP67 rating the Bounce is effectively dust tight, giving users confidence to use it in dusty outdoor environments and on the go.

The IP67 rating means the Flex 2 is fully protected against dust ingress, and owners feel comfortable using it outdoors or tossing it in backpacks, though the silicone coating can pick up surface lint that needs occasional wiping.

With its IP67 certification and rugged enclosure, the SoundLink Max is effectively dust tight for the internals, letting owners use it on beaches, decks and other gritty environments without worrying about particles harming the drivers, though the exposed USB C and aux ports can still collect sand with heavy beach use.

The Move 2’s IP56 dust protection keeps wind-blown dirt from causing issues in everyday outdoor use, even if it offers slightly less complete sealing than IP67 speakers aimed at more extreme conditions.

Despite its strong waterproofing, reviewers point out that the StormBox Mini+ lacks an official dust rating, leaving some skepticism about how well it will cope with sand or dusty environments.
