Short answer: the W-King X10 stretches a charge far longer, but the JBL Boombox 4 is louder for its size. The X10 offers 70W RMS with 120W peak, a 42-hour battery with power bank, IPX6, 106dB max volume, indoor and outdoor EQ modes, and Bluetooth 5.0 with 100ft range, but its treble is heavily rolled off and it has less bass than the top ranked. The Boombox 4 is overpriced and drops Aux.
Buy the JBL Boombox 4 if sound quality matters more than the price. Buy the W-King X10 if the price matters more than sound quality.
Battery life favors the W-King X10: rated for 42 hours against 28 hours for the JBL Boombox 4.

Older models: the JBL Boombox 3 (ranked lower, rated 3.8/5), the JBL Boombox 2 (ranked lower, rated 3.5/5) and the JBL Boombox (ranked lower, rated 2.9/5).
Pros: Pretty insane output capability for the size. IP68 protection and Auracast pairing with other current JBL speakers. Measured bass extension of 41Hz (-10dB).
Cons: Pretty overpriced for the category. Better than the Boombox 3 mostly because there are more 7 EQ bands instead of just 3 and it can be better tuned. Try Oluv’s EQ for it. Out of the box sounds worse than the Boombox 3. No Aux input.
