Short answer: these aren’t really competing for the same job. The Flip 7 ranks #14 of 145 medium speakers at $149.95, while the ULT Field 5 ranks #45 of 83 large speakers at $198.
The size difference explains most of the gap. Our notes call the Flip 7 a very neutral speaker, small enough to be almost pocket-sized, with slightly more treble and slightly deeper bass than the well-regarded Flip 6, and it costs a fraction of the much larger ULT Field 5. The ULT Field 5’s own notes are more measured: bass that’s not as deep as others in its own, larger category, and sound quality described as just okay overall. The Flip 7’s only real knock is a small bump around 4kHz that keeps it just a touch less neutral than the Flip 6 it replaced.
The ULT Field 5 earns its size and price with battery life and features: a 25-hour battery against 14 hours on the Flip 7, a built-in microphone, an aux input, stereo sound with true wireless stereo pairing, and LDAC support alongside SBC and AAC. It also has one quirk worth knowing about, a dedicated ULT bass-boost button that our notes say makes a loud tone when pressed.
Buy the JBL Flip 7 if you want a genuinely pocketable speaker with accurate, well-reviewed sound for a fraction of the price.
Buy the Sony ULT Field 5 if you need the size, the longer battery life, and stereo sound, and can accept that its own notes rate the sound quality as just okay.

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

Sony ULT Field 5: $198 Amazon eBay
Older models: the Sony SRS-XB43 (ranked lower, rated 3.5/5) and the Sony SRS-XG300 (ranked lower, rated 3.1/5).
Pros: A tough 3.3kg portable with IP67 protection, LDAC/AAC support, aux input, a 10-band app EQ, Party Connect, USB-C power-bank output and a claimed 25-hour battery. Reviews find it energetic and dynamic with substantial bass, enough volume for a yard, and two ULT modes that let bass-focused listeners choose a deeper or punchier presentation.
Cons: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth. Deep bass is less authoritative than the enclosure suggests, and the loud confirmation tone when pressing the ULT button is an unnecessary annoyance. Use the app EQ and audition it before buying for detail-focused music.
