Short answer: the JBL Flip 6. It ranks #12 of 136 medium speakers by sound quality at $114.95; the Ultimate Ears Megaboom 4 ranks #132 and costs $200, which makes this an easy call rather than a real tradeoff.
What the JBL Flip 6 offers: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. Watch for: Not stereo. Some slight upper mids emphasis. The TL version (made in Vietnam) tweeter can sound somewhat scratchy and doesn’t sound as good as the GG version (made in China)
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
Buy the JBL Flip 6. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so the other one has nothing left to offer.
Skip the Ultimate Ears Megaboom 4 if sound quality matters to you. It ranks near the bottom of the 136 medium speakers.
There is a real battery-life gap here: the Ultimate Ears Megaboom 4 is rated for 20 hours, the JBL Flip 6 only 12 hours.
