Short answer: the Loewe We. Hear Pro. It ranks #20 of 126 large speakers by sound quality, rated 4.3/5, at $275; the Sony ULT Field 5 ranks #59, rated 3.5/5, and costs $348, so there is not much of a tradeoff to weigh.
The Loewe We. Hear Pro is the better-sounding, lighter option. A true stereo speaker with excellent separation, a warm balanced midrange and furniture shaking bass at moderate volume. At 4.9 lbs (2.2 kg) it weighs noticeably less than the Sony ULT Field 5 at 7.3 lbs (3.3 kg). Watch for: It runs out of headroom quickly: above about 70% volume the bass drops away, the treble gets harsher, and near maximum there is heavy compression and clipping, so the JBL Xtreme 4, Harman Kardon Go + Play 3 and Bogasing S8 Pro Max all sound fuller and cleaner when played loud.
The case for the Sony ULT Field 5: A tough, waterproof party speaker with loud, bass focused output, an aux input, a power bank and a long battery. It supports LDAC Bluetooth, which the Loewe We. Hear Pro lacks. The tradeoff: It prioritizes bass and loudness over fidelity: reviews find the upper mids and highs subdued, with limited stereo separation and soundstage depth.
Buy the Loewe We. Hear Pro. 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.
