Review: Great little portable speaker - It's easy to pack around and has pretty good sound for such a little guy. Primary uses are music and audiobooks and the sound quality good enough that I'm satisfied. It's not Bose, but it sure ain't bad. I use it in the shop, out by the pool and when I'm gardening. Outdoors the sound travels a bit better if there is a wall or something solid behind the speaker. The loop makes it easy to carry or hang up and the 360⁰ sound means less fussing around with location and direction. Connected to my Android, playing on Spotify, I can crank it all the way up with no distortion or crackling. But, I only did that this one time, so I could note it in the review. It's pretty freaking loud. It's solid with a rubber cap on both the top and bottom. In case of a drop, those could be lifesavers. I've never tossed it in the water, so cannot attest to it's water resistance. It connects quickly and easily to any Bluetooth device and the buttons on top provide easy access to pairing, pause and power. It will power down if left unused for a few minutes to preserve the battery. That's a nice function. I'm not wild about the HUGE volume controls on the front. I think they're ugly and detract greatly from the overall appearance of the speaker. Overall, good value for the money.
Review: Great Sound from Small Package (and it freakin’ floats) - Got this on a recent sale/discount desertcart had as the wife keeps losing our Bluetooth speakers, so I didn’t want to spend too much. It’s waterproof and floats (actually floats I didn’t believe the product description). Figured being so small and waterproof it wouldn’t have decent sound but it actually punches well above its size. Has an outdoor button to amplify the sound more (when you’re at the pool or a BBQ). You can connect 2 for stereo sound. Easy and intuitive to use/connect to phone etc. I think these are worth the original MSRP but if you see one on sale I’d grab one. Great little speaker!

### ⭐⭐⭐⭐⭐ This thing is great
*by T***G on June 21, 2026*

This is a great travel speaker. Extremely easy to setup…look less than 5 minutes. And the sound is wonderful. Great vocal sound with just enough mid and bass. The volume is great for rooms or hotels. It’s small enough to take everywhere. Sounds much better than my Sonos Roam and much easier to deal with.
