Short answer: the Tronsmart Bang 2. It ranks #45 of 85 large speakers by sound quality, rated 3.6/5, at $109.99; the Sony ULT Field 5 ranks #46, rated 3.5/5, and costs $348, which makes this an easy call rather than a real tradeoff.
Why pick the Tronsmart Bang 2: In Jagist’s side by side tests, the Bang 2 (after its firmware update) was picked over the Soundcore Boom 2 and over the JBL Xtreme 5, which distorted at high volume, and it kept its bass above 40% volume where the Tribit Stormbox Lava fell apart. The tradeoff: Verdicts against the Boom 2 and the Lava were split: Dominik Reviews preferred the Boom 2, and several listeners found the Bang 2’s mids muffled and its highs subdued without custom EQ.
Why pick the Sony ULT Field 5: 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. Watch for: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Buy the Tronsmart Bang 2. It is rated higher for sound quality than the Sony ULT Field 5 and costs less, so only choose the other one for a particular feature it does better.

Tronsmart Bang 2: $109.99 Best Buy Tronsmart eBay
Pros: In Jagist’s side by side tests, the Bang 2 (after its firmware update) was picked over the Soundcore Boom 2 and over the JBL Xtreme 5, which distorted at high volume, and it kept its bass above 40% volume where the Tribit Stormbox Lava fell apart. Listeners also mostly preferred it to the JBL Xtreme 4. A racetrack woofer, two tweeters and two passive radiators are rated for 90W and 105dB. Tronsmart rates the battery at 26 hours at half volume with the lights off, and it adds IPX6 water resistance, a handle plus a detachable shoulder strap, app EQ, light effects, stereo and multi-speaker pairing, aux, TF card and USB playback, and a USB-C power bank.
Cons: Verdicts against the Boom 2 and the Lava were split: Dominik Reviews preferred the Boom 2, and several listeners found the Bang 2’s mids muffled and its highs subdued without custom EQ. Next to the Tronsmart Fiitune X30 it turned into a jumble of sound near full volume, and the EarFun UBoom X clearly beat it. It needed a firmware update to sound its best, and at 2.63 kg it is heavy for its size.

Sony ULT Field 5: $348.00 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.
