Short answer: the Soundcore Motion X500. It ranks #27 of 105 large speakers by sound quality, rated 4.1/5, at $99.99; the Sony ULT Field 5 ranks #55, rated 3.5/5, and costs $348, so there is little reason to consider the other one.
The Soundcore Motion X500 is the better-sounding, lighter option. 40W stereo with 3-driver layout (two tweeters + woofer). At 4.6 lbs (2.1 kg) it weighs noticeably less than the Sony ULT Field 5 at 7.3 lbs (3.3 kg). Watch for: A little bright on top, a custom EQ can flatten things out a bit.
The Sony ULT Field 5 is the longer-running pick. 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 12 for the Soundcore Motion X500. It supports AAC Bluetooth, which the Soundcore Motion X500 lacks. It links with other speakers (Party Connect up to 100 speakers), which the Soundcore Motion X500 cannot. 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 Soundcore Motion X500. 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.

Sony ULT Field 5: $348.00 Amazon $348.00 eBay
Older models: the Sony SRS-XB43 (ranked lower, rated 3.5/5) and the Sony SRS-XG300 (ranked lower, rated 3.1/5). See every Sony XB and ULT generation.
Same family: the Sony ULT Field 1 (smaller model, rated 3.1/5), the Sony ULT Field 7 (smaller model, rated 3.2/5), the Sony ULT Tower 10 (smaller model, rated 3.9/5), the Sony ULT Field 3 (smaller model, rated 3.4/5), the Sony ULT Tower 5 (larger model, rated 4.5/5), the Sony ULT Tower 7 (larger model, rated 4.7/5), the Sony ULT Tower 9 (larger model, rated 4.2/5) and the Sony ULT Tower Max (larger model, rated 4.8/5).
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.
