Short answer: the Ultimate Ears Boom 4 if sound quality matters most, the Oontz Angle 3 if price matters most, though neither ranks well in its class. The Ultimate Ears Boom 4 ranks #114 of 182 medium speakers, rated 2.9/5, at $114.99. The Oontz Angle 3 ranks #177, rated 2.1/5, at $19.98, $95.01 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 Boom 4 is the better-sounding, tougher option. A tough waterproof speaker that floats, with USB-C charging, app EQ and pairing with other UE speakers. It is rated IP67 against IPX5 for the Oontz Angle 3. It charges over USB-C rather than Micro USB. The tradeoff: Not much improvement over the old ones.
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 Boom 4 lacks.
Buy the Ultimate Ears Boom 4 if sound quality is the priority over the price, or the Oontz Angle 3 if the price is the priority over sound quality.
