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 similar in directivity, battery life, and build quality, though the BOOM 4 can get a bit louder.
