Short answer: the JBL Xtreme for battery life, the Doss Soundbox XL for output. The Soundbox XL offers 32W, 100dB max volume, a 10-hour battery, IPX4 and TWS pairing, but it sounds a little hollow. The Xtreme’s 15-hour battery is the advantage, though it has issues with bass distortion at high volumes.
Buy the Doss Soundbox XL new; the JBL Xtreme is no longer sold new, so it only makes sense as a used find.
There is a real gap in water resistance: the JBL Xtreme at IPX7 (brief submersion) against the Doss Soundbox XL, which has IPX4 (splashing).
