About this deal
Performance doesn’t suffer for the size. Across most genres, the speaker sounds well-balanced with surprisingly strong bass. Pair two together for a stereo effect. Not as small as the Tribit, but still small enough to fit in your hand at about 4" high and 3.5" diameter. Charging the Ultimate Ears Wonderboom 3 is perhaps my only real disappointment in testing. Going from dead, the speaker took over two hours to reach the chime that indicates a full charge. This is probably due to Micro-USB charging, which is rather outdated. I wish it had USB-C charging like most of my other devices. UE Wonderboom 3 review: Verdict
That unmistakable yellow charger has been replaced with an Apple-esque white cable but, overall, the Wonderboom 2 looks and feels more premium than the original. Sonically, the UE Wonderboom 2 is fantastic for its size. The speaker plays much louder than you would expect, especially with the Outdoor Boost enabled. There’s a bit of distortion at max volume, but if you keep it below 80%, music sounds great.Once WONDERBOOM 2 is on and connected to your mobile device, just hit play to begin streaming your music. As we mentioned earlier, the Wonderboom 2 has an IP67 rating, meaning it now brings with it dust resistance on top of last year’s IPX7 water resistance. You can also drop the speaker repeatedly from 5ft so it’s a speaker that can take a beating whether you’re hiking or at the pool.
The speaker has a sleek design, with a cylindrical shape and a durable exterior that is resistant to dust, water, and drops. Its small size also makes it highly portable and easy to carry around.Of course, the biggest upgrade is how the Wonderboom 2 handles Ultimate Ears Double Up feature. If you buy two Wonderboom 2's you can pair both speakers together to form a stereo pair, meaning you have both left and right channels. The older model could use the double up feature; however, it didn't create a stereo pair, but rather just allowed you to play the same audio from both speakers at once.
