This tiny speaker is entirely unimpressive, with thin, closed-in sound and wimpy bass. It's hardened against the elements, but that doesn't make up...

Tiny; Waterproof; dustproof; drop-proof; Two can be linked into a stereo pair

Thin; closed-in sound; Wimpy bass; Expensive for what's delivered

I sat on the midsummer evening and ended up at Smartson.se. There I saw that I could become a test pilot for a mobile speaker! Wonderfully I thought, the wife has blocked my accounts because I have the same impulse control as an 8-year-old with ADHD when it comes to shopping technology that plays...

Wonderboom is the compact but powerful speaker from Ultimate Ears. Two years after the first model, the American manufacturer announced the second model, the Wonderboom 2, in June 2019 with the promise of more powerful sound, an unparalleled range, superior waterproofing, and wireless stereo...

Waterproofing; Battery life; Outdoor mode; Small size

Incompatible with other Ultimate Ears models; No USB Type-C; No headphone jack; Latency

It's difficult to get a lot of power out of a small speaker: You generally need more physical volume to produce more audio volume. Ultimate Ears pushes those limits with the UE Wonderboom, a tiny Bluetooth speaker that delivers a sound loud enough to fill a room. The Wonderboom doesn't produce the cleanest highs or distortion-free deep lows, but it's portable, rugged, and fairly priced at $99.99. The JBL Charge 3 ($95.99 at Amazon) delivers a bit more audio finesse in a larger package, but the Wonderboom is a solid alternative. Design The Wonderboom ($68.00 at Amazon) is a squat, rounded cylinder shaped vaguely like a Japanese lantern. It's available in six different colors, including black, blue, gray, orange, pink, and purple. It measures 3.6 inches around, 4.0 inches high, and weighs 15.2 ounces, making it too large to slip in a jacket pocket, but a fine size for a bag. A small, thick elastic loop on the top lets you easily clip the speaker to your bag or hang it from a hook...
