Short answer: the Ultimate Ears Wonderboom 4 for better sound quality, the Oontz Angle 3 for the lower price, though neither ranks well in its class. The Ultimate Ears Wonderboom 4 ranks #110 of 182 medium speakers, rated 2.9/5, at $64.99. The Oontz Angle 3 ranks #177, rated 2.1/5, at $19.98, $45.01 cheaper. Both are rated below 3.0/5 among the 182 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Wonderboom 4 is the better-sounding, lighter choice. A small, tough waterproof speaker with a strap loop and USB-C charging, easy to clip on a bag for outdoor trips. At 0.9 lbs (420 g) it weighs noticeably less than the Oontz Angle 3 at 1.3 lbs (580 g). It is rated IP67 against IPX5 for the Oontz Angle 3. It charges over USB-C rather than Micro USB. The tradeoff: Bass isn’t as deep as the top-ranked speakers and is a little thuddy.
What the Oontz Angle 3 does well: A very cheap splash resistant speaker with an aux input for casual use around the house. It keeps a wired aux input, which the Ultimate Ears Wonderboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom 4.
Buy the Ultimate Ears Wonderboom 4 if sound quality is the priority over the price, or the Oontz Angle 3 if the price is the priority over sound quality.
