Short answer: the JBL Flip 7, without much of a contest. It ranks #15 of 164 medium portable speakers at $119.95, while the Megaboom 4 ranks #159, near the bottom of the same list, at $200, $80.05 more expensive for a much lower-ranked speaker.
The Megaboom 4’s own review does not hold back. Its cons list “a lot of distortion at higher volumes,” rolled-off treble, disappointing loudness, and closes with the blunt line “they really screwed this up.” The Flip 7, by contrast, earns praise as “a very neutral speaker” that’s “almost pocket size,” with slightly deeper bass and a touch more treble than its well-liked predecessor, the Flip 6. Its only real knock is a small bump at 4kHz that keeps it just short of the Flip 6’s neutrality, a minor complaint next to the Megaboom 4’s list.
The Megaboom 4 does hold two real advantages. Its 20-hour battery beats the Flip 7’s 14 hours, and it supports Ultimate Ears’ PartyUp mode for syncing up to 50 UE speakers together, along with true wireless stereo pairing, both of which the Flip 7 lacks. It’s also fully omnidirectional, throwing sound 360 degrees around the cylinder, while the Flip 7 fires from one side.
Everything else favors the Flip 7: a higher IP68 rating against the Megaboom 4’s IP67, a louder 100dB max volume against 91dB, a newer Bluetooth 5.4 radio with AAC support versus 5.1 and SBC-only, a 7-band EQ, and it’s less than half the weight at 1.2 lbs (544 g) versus 2.4 lbs (1.1 kg).
Buy the JBL Flip 7 for meaningfully better sound at a lower price; on the numbers here it’s not a close call.
Buy the Ultimate Ears Megaboom 4 only if 360-degree sound dispersion, PartyUp multi-speaker syncing, or the extra battery life outweigh the distortion and volume complaints in its own review.

The Two Speakers In Full
JBL Flip 7: $119.95 Amazon eBay
Older models: the JBL Flip 6 (ranked higher, rated 4.2/5), the JBL Flip 5 (ranked lower, rated 3.3/5) and the JBL Flip 4 (ranked lower, rated 3.3/5).
Pros: A very neutral speaker, very small, almost pocket size. Just slightly more treble than the Flip 6 which was already a great speaker. Slightly deeper bass than the Flip 6. IP68 protection, a 7-band app EQ, Auracast and a USB-C digital audio input. Measured bass extension of 59Hz (-10dB).
Cons: A little bit of a bump at 4kHz, not quite as neutral as the Flip 6. On balance it is the slightly worse of the two.
