A small speaker that sounds awesome delivers crisp sound and good bass.

[This review was collected as part of a promotion.] God, do I love this speaker. I'm actually struggling to come up with anything negative about it, it's just a good solid device that exceeded all of my expectations. The speaker was packaged well in a box that was fun to open (you pull it up vertically to reveal the speaker, standing upright, which was a cool little first impression). The navy-blue color looks great, and it has an overall sleek design. There are only a few buttons and I'm big into the modern, minimalist look. The battery, so far, hasn't been an issue at all - I've been using it on and off for almost a week now and I haven't had to charge it after first using it, the box says that it can go for up to 24 hours and I definitely believe it. But most importantly, the sound quality of this thing really surprised me, I've owned a couple of these pill-shaped speakers, and I chose to directly compared it to one I've had for years that I consider to be good but not great - and the jump in quality was like night and day. Music sounds CRISP coming out of this thing, crisp and clean with no popping or "speaker-y" noises or whatever, and with nothing boosted or emphasized in an obnoxious way like some other speakers. I also really appreciate two features that I haven't used yet: the fact that it has an SD card slot, and the fact that you can sync two of these together and create a little stereo surround sound system. Both just cool little bonuses that I definitely don't consider to be standard features (compared to similar speakers). Really the only problem I have with this thing is the little loop, that you can use to hang the speaker on hooks and knobs and such. It's a fabric knot that looks and feels exactly like a shoelace, and it feels like it could get undone/rip, so I'm choosing not to use it. I wish it were made of something more like a stretchy rubber, or maybe it could be replaced with a plastic hook or something. But that's a very minor complaint when this thing is so, so good in pretty much every other way. This speaker really surprised me and I can highly recommend it.
