Short answer: the Sony ULT Field 5. It ranks #52 of 97 large speakers by sound quality (rated 3.5/5) at $348 and is still sold new; the Soundcore Trance ranks #92 (rated 2.1/5) and is discontinued, so it is only an option used.
The Sony ULT Field 5 is the better-sounding, longer-running option. A tough 7.3 lbs (3.3 kg) 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. It is rated for 25 hours of battery against 18 for the Soundcore Trance. It supports LDAC Bluetooth, which the Soundcore Trance lacks. Watch for: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Why pick the Soundcore Trance: 80W power with up to 105dB output and BassUp technology. Watch for: Hugely recessed midrange and treble.
Buy the Sony ULT Field 5. It is rated higher for sound quality and still sold new, while the Soundcore Trance is discontinued.

The Two Speakers In Full
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.
