A:Answer Hi, I used a pair of Sonos 1's in a covered outdoor kitchen year-round; estimate they were out there for about 4+ years, never had a problem with moisture. One was about 5' above our grill / smoker, so also exposed to those elements. Pretty robust speaker. I would expect these never were exposed to direct moisture, I.e. rain or snow, but the humidity of St. Louis, no problems.
