Short answer: the JBL Boombox 4. It ranks #20 of 113 boombox speakers by sound quality, rated 4.0/5, at $549.95. The Aiwa Exos-10 ranks #44, rated 3.5/5, at $399.99, $149.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL Boombox 4 is the better-sounding, longer-running choice. An extremely loud boombox for its size with fully waterproof, dustproof build, a long battery and a flexible app EQ. It is rated for 28 hours of battery against 12 for the Aiwa Exos-10. Watch for: Pretty overpriced for the category.
Why pick the Aiwa Exos-10: A loud party boombox with FM radio, a remote, and retro VU meters. It keeps a wired aux input, which the JBL Boombox 4 lacks. Watch for: It lacks deep bass: even with bass maxed it rolls off around 50Hz, where the W-King X20 and Zealot boomboxes reach deeper, and it is about 2dB quieter at full volume.
Buy the JBL Boombox 4. It is rated higher for sound quality, and the $149.96 you would save on the Aiwa Exos-10 does not close the gap.
