Short answer: the JBL Flip 7. It ranks #14 of 142 medium speakers against the ULT Field 3’s #60, and costs $11.95 less at $149.95 versus $138. This is not a close call.
The Flip 7 is a genuinely neutral speaker. Its pros describe it as very neutral and small, almost pocket size, with slightly deeper bass and just a bit more treble than the well-regarded Flip 6. The only knock is a small bump at 4kHz that keeps it from being quite as flat as its predecessor.
The ULT Field 3 has a real design conflict in its sound tuning. Its cons note it sounds a bit hollow and boosted in the treble, and that the custom EQ and the ULT bass-boost button cannot be used together, turning on ULT disables the EQ, while bass is very weak with ULT off. Reviewer GYMCADDY pitted it directly against the JBL Charge 6 and the ULT Field 3 lost despite being the larger speaker.
What the ULT Field 3 offers in return: a built-in microphone, Party Connect for linking up to 100 speakers, stereo pairing, and a USB-C power bank function, none of which the Flip 7 has. It also runs longer on a charge, rated for 24 hours against the Flip 7’s 14.
Buy the JBL Flip 7 for better, more neutral sound at a lower price. It is the clear pick unless you specifically need the ULT Field 3’s extra features.
Buy the Sony ULT Field 3 if all-day battery life, a microphone for calls, or large-group Party Connect pairing outweigh the sound quality gap for you.

The Two Speakers In Full
JBL Flip 7: $149.95 Amazon eBay
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. 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.
