Tribit Stormbox Lava vs Sony ULT Field 5

Last updated: September 26, 2026

Short answer: the Sony ULT Field 5 for features and battery, the Tribit Stormbox Lava for bass depth. The ULT Field 5 is IP67 rated with a 25-hour battery, a 10-band app EQ, Party Connect for up to 100 speakers and USB-C in/out, but its bass is not as deep as others and its ULT button makes a loud tone when pressed. The Lava has fantastic bass extension, though it is heavy for its size.

Tribit Stormbox Lava vs Sony ULT Field 5

The case for the Tribit Stormbox Lava: fantastic bass extension that goes deeper than the Soundcore Boom 2, and firmware 2.0.0 brought a big improvement in neutrality. The catch: it’s quite heavy for its size, has some bass boost way down low, and some peaks in the treble and upper mids.

Buy the Tribit Stormbox Lava. It is rated higher for sound quality than the Sony ULT Field 5 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Tribit Stormbox Lava ranking card

Pros: A powerful, IP67-rated portable speaker with a measured 44Hz -10dB bass point, 10-band app EQ, aux input and 24-hour claimed battery life. Independent reviews find that it gets loud with impactful bass, and careful EQ or current firmware can produce relatively clean sound through the mids and highs. Measured bass extension of 44Hz (-10dB).

Cons: XBass can make the low end muddy and obscure vocals, while the deepest notes lose authority and clarity falls at maximum volume. It is heavy for its size, its front-facing design has a narrow soundstage, and one review noted a brief sound interruption while changing volume; use a restrained EQ rather than expecting neutral sound out of the box.

Setup: Try out the Alan Ross EQ’s at this timestamp in his video There’s also a max bass EQ from Oluv and you can turn down the lowest slider for it to be more neutral

Sony ULT Field 5 ranking card

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.
