Short answer: the Tribit Stormbox 2. It ranks #91 of 150 medium speakers by sound quality, rated 3.0/5, at $70; the Ultimate Ears Wonderboom 4 ranks #95, rated 2.9/5, and costs $78.95, which makes this an easy call rather than a real tradeoff.
The Ultimate Ears Wonderboom 4 is the lighter choice. At 0.9 lbs (420 g) it weighs noticeably less than the Tribit Stormbox 2 at 1.3 lbs (593 g). The catch: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
The Tribit Stormbox 2 is the longer-running choice. A little better sounding than the Stormbox 1, less of a rolled off treble. It is rated for 24 hours of battery against 14 for the Ultimate Ears Wonderboom 4. It supports AAC Bluetooth, which the Ultimate Ears Wonderboom 4 lacks. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. The tradeoff: Drivers on the side, so it will have a rolled off treble listening to it face on.
Buy the Tribit Stormbox 2. It is rated higher for sound quality than the Ultimate Ears Wonderboom 4 and costs less, which makes it the one to get unless you need something the other one does better.
