Review: Perfect little waterproof speaker - I bought this to affix to a Paddle North lake float and it's a perfect match. Our pontoon doesn't have external speakers so I wanted something with good sound that won't sink to the bottom of the lake if my mount disengages. It can get plenty loud and the sound isn't shabby for such a small speaker. I leave it in the default startup sound profile - which it reverts to with every startup. The "outdoor mode" is a wee bit louder and definitely brighter but doesn't anything that can't be obtained with Spotify's equalizer. The podcast mode sounds like an AM radio and I can't envision ever using it unless I want to be reminded how well the default mode is. The speaker has the usual UE build quality I'm used to and so far we haven't run out of juice after several hours of use. This will also make a great travel companion for hotel rooms/pool side listening and desertcart has some nice inexpensive travel cases for under $15. This won't compete with larger speakers for sound quality but for what it is and what I need, the performance and price are unbeatable.
Review: LOVE THESE! - After reading the reviews, I was skeptical, but I was in need, so I figured what the heck. They're a good price. I was stunned at how good they sound! Linking them together took a minute but it's not hard. I have a BOOM 3 and I'm slightly annoyed that you can't operate these via the app. I got spoiled. Battery life is accurate, I used them all day, playing on either end of the house. They stay connected and I didn't have any issues. I love their small size, too. Easy to plant in discreet places for a party or other social event.
