Review: The best portable speaker you can find! - Great portable speaker ! So far, it has surpassed all the other ones I've tried. Very good sound with good bass for it's compact size. It's also waterproof and falls proof, and it floats, which is great. It seems very well made and it looks good too! Definitely my favorite speaker, I would recommend and I liked it so much I bought a second one to pair with the first one I bought. You want a solid speaker with great sound, that you can bring anywhere with you, this is it! FYI it's been a year that I bought the first one and I use it regularly (in the shower, the car, doing the dishes...) and it still looks brand new and performs as well as day 1!
Review: Small but mighty and at a reasonable price point - I love this speaker! Small size makes it super portable without compromising sound quality. The added bass you get by pressing g the button at the bottom gives you great sound when watching movies. Very easy to use and set up! Lasts quite a while on a full charge! I already had one for my classroom and this is my second one for home. Definitely recommend. I bought a case for it afterwards for travelling.

### ⭐⭐⭐⭐⭐ Great Sound from Small Package (and it freakin’ floats)
*by J***N on 28 June 2026*

Got this on a recent sale/discount Amazon 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!
