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: 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!
