Short answer: the JBL Flip 6 is the more neutral speaker; the Sony ULT Field 1 is the tougher choice for drops, water, and stereo pairing. JBL ranks #12 of 142; Sony ranks #79 of 142.
Flip 6 has 30W output, 98dB maximum level, and a 56Hz bass specification in a 544g package. Its sound is balanced, though it remains mono and has only a claimed 12-hour battery.
ULT Field 1 weighs 650g, is IP67, survives drops, and can pair with a second unit for stereo. Its upper-midrange peak and rolled-off treble make it less accurate, but its ruggedness is meaningful.
Buy the JBL Flip 6 at $129.95 if neutral sound is your main requirement.
Buy the Sony ULT Field 1 at $98 if you need stereo pairing and a more abuse-resistant portable.
What the JBL Flip 6 gets right: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. The tradeoff: Not stereo.
On the Sony ULT Field 1 side: IP67 rated, survives drops and 1m submersion. Set against that: Upper midrange peak, rolled off treble.

JBL Flip 6: $129.95 Amazon B&H Photo Video eBay
Pros: A very neutral speaker, very small, almost pocket size, a huge sound quality leap over the Flip 5. Measured bass extension of 56Hz (-10dB).
Cons: 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)
