JBL Boombox 4 vs Soundcore Motion Boom+

Last updated: October 1, 2026

Short answer: the JBL Boombox 4 for measured output, the Soundcore Motion Boom+ for value stereo power. The JBL has pretty insane output for its size with a 7-band EQ, but it is overpriced, sounds worse than the Boombox 3 out of the box and drops the aux input. The Motion Boom+ pushes 80W stereo from dual 30W woofers and dual 10W titanium tweeters, but its presets are warm with rolled-off treble and need a custom EQ.

JBL Boombox 4 ranking card

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.

Soundcore Motion Boom+: $122.42 after $40 coupon Discontinued Amazon eBay

Soundcore Motion Boom+ ranking card

Newer model: the Soundcore Boom 2 Plus, ranked higher, rated 3.6/5.

Pros: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank. Measured bass extension of 52Hz (-10dB).

Cons: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6kHz peak comes out when volume is above about 60%. Not much deeper bass than a Motion Boom and a lot less deep bass than other speakers in the class. Discontinued.
