Our Verdict
Ultimate Ears BOOM 4
Ultimate Ears WONDERBOOM 4
The Ultimate Ears WONDERBOOM 4 is a better portable speaker for most uses than the Ultimate Ears BOOM 4. While they're both available at similar price points, the WONDERBOOM 4 represents better value for most uses. It's more portable, has a more balanced default sound profile, and features Bluetooth multi-device pairing. Otherwise, the two speakers are very similar when it comes to soundstage performance, battery life, and build quality.
