Short answer: the Soundcore 2 is the value pick for stereo playback, long runtime and aux input, while the Wonderboom 4 is the smaller, more water-resistant grab-and-go speaker. Soundcore claims 24 hours from a 0.7 lbs (318 g) cabinet and includes two drivers, whereas Ultimate Ears gives you IP67 protection and a more omnidirectional presentation. Neither has app EQ, and neither should be chosen for deep bass.
What the Soundcore 2 offers: 24+ hour battery life from a 5200mAh cell. Watch for: Bass doesn’t go as deep as others.
Buy the Soundcore 2 if you want the longer battery, stereo drivers and aux input at the lower price.
Buy the Ultimate Ears Wonderboom 4 if small size, float-friendly IP67 protection and wider room coverage matter more than features or bass weight.

The Two Speakers In Full
Soundcore 2: $29.99 Amazon eBay
Newer model: the Soundcore 3/Soundcore Select 2, ranked higher, rated 3.4/5.
Pros: Soundcore 2 uses 2x 38mm fullrange. Its 318 g, claimed 24 hours (Manufacturer specified) battery life, IPX7 protection, aux input and stereo playback make it a practical option for its intended room or portable use.
Cons: Its 70Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size. There is no companion app. No EQ adjustment.
