Over 138,000 Amazon shoppers gave the speaker a five-star rating because the audio is crisp, the bass is deep and it just looks cool. Plus, thanks to magical Bluetooth, the little guy works up to 100 feet away from your device. With 10+ watts of power, this thing is LOUD — so feel free to use it in the backyard on the increasingly rare warm weekends. It's only 10 ounces, it's easy to haul out at a moment's notice.

Shoppers swear by its long battery life (up to 14 hours) and easy setup. "This is the best Bluetooth speaker I have ever owned," raved a five-star reviewer. "It lasts for days on a single charge, and pairing is hassle-free...Sturdy and really well made."

Adds another fan: "I have had this speaker for several months, and it is fantastic. It's very small, with a similar footprint as a cellphone, and the build quality is shockingly good, with a metal grill, high-quality plastics, and nice silicone end pieces. It has excellent sound with surprisingly good bass."

Other reviewers praise the rugged, water-resistant design. "Just buy it," says another reviewer. "I love this speaker. Small and packs a punch for it'd size. Great battery life.. Two weeks ago, I had it sitting on my tractor while working. Well, when I drove the tractor back it had fallen off and I couldn't find it for two weeks. Sitting out in the yard. It's stormed several times. I was about to order a new one... Found it today. Still works!!"

If that's not proof of a great speaker, we don't know what is.
