Short answer: the JBL Flip 7. It ranks #15 of 164 medium speakers, 95 spots ahead of the Boom 4’s #110, and the two cost essentially the same at $119.95 versus $149.99.
The Flip 7’s tuning is the difference. Its pros call it a very neutral speaker, very small and almost pocket size, with slightly deeper bass and just a touch more treble than the Flip 6, itself already well regarded. Its only real flaw is a small 4kHz bump that keeps it from matching the Flip 6’s flatness exactly.
The Boom 4 is a modest refresh at best. Its own cons state plainly that there is not much improvement over the old ones, and call out weak bass extension with thuddy bass, plus distortion above 90 percent volume. What it does add over older Booms is USB-C charging in place of Micro-USB, an IP67 rating, and the ability to float.
Everything else lands close: battery life is 14 hours on the Flip 7 versus 15 on the Boom 4, both offer app-based EQ, and both are similarly sized and weighted. The Boom 4 adds stereo pairing and TWS support that the Flip 7 lacks, while the Flip 7 counters with Auracast party pairing and a higher 100dB max volume against the Boom 4’s 85dBC.
Buy the JBL Flip 7 for meaningfully better, more neutral sound quality at the same price.
Buy the Ultimate Ears Boom 4 only if floating in water or stereo pairing two units matters more to you than sound quality.

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.
