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: Great for the Beach! - Bought this speaker for my beach trip. Wasn’t worried about water or sand with this speaker. It has a very clean sound, can get pretty loud for its size. Bass is okay, but expected for speaker of this size. The build quality is great, very portable, battery lasted the entire day at the beach and night. Never had a connection problem with Bluetooth either. Overall a great speaker for the price.

I usually don’t give 5 stars when I write reviews, but this speaker deserves it! Don’t let the small size fool you—this little speaker is powerful. The sound is clear and fills the room really well. I also love the color; it adds a nice, stylish touch. It’s small, portable, and sounds great. I’m very happy with it!
