Short answer: the Loewe We. Hear Pro. It ranks #20 of 120 large speakers by sound quality, rated 4.3/5, at $275; the JBL Xtreme 4 ranks #43, rated 3.8/5, and costs $309.95, so there is little reason to consider the other one.
The Loewe We. Hear Pro is the better-sounding pick. A true stereo speaker with excellent separation, a warm balanced midrange and furniture shaking bass at moderate volume. It supports AAC Bluetooth, which the JBL Xtreme 4 lacks. It keeps a wired aux input, which the JBL Xtreme 4 lacks. The catch: 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.
What the JBL Xtreme 4 does well: A rugged, waterproof speaker with clear, punchy sound, a swappable battery, a power bank and excellent real world battery life. The tradeoff: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
Buy the Loewe We. Hear Pro. It is rated higher for sound quality than the JBL Xtreme 4 and costs less, so only choose the other one for a particular feature it does better.
