Short answer: the JBL Boombox 4. It ranks #20 of 113 boombox speakers by sound quality, rated 4.0/5, at $549.95. The Bumpboxx Flare8 Pro ranks #74, rated 2.8/5, at $449, $100.95 cheaper, which does not close the gap in sound quality.
The case for the Bumpboxx Flare8 Pro: A retro boombox for karaoke and live use, with two wireless mics, guitar and mic inputs, and lots of power. It keeps a wired aux input, which the JBL Boombox 4 lacks. It has a microphone input for karaoke or announcements, which the JBL Boombox 4 lacks. The catch: No independent measurements or tested reviews have been published, so its tonal balance, bass extension and real output can’t be compared with ranked speakers.
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 10 for the Bumpboxx Flare8 Pro. At 13.2 lbs (5.98 kg) it weighs noticeably less than the Bumpboxx Flare8 Pro at 19 lbs (8.6 kg). The catch: Pretty overpriced for the category.
Buy the JBL Boombox 4. It is rated higher for sound quality, and saving $100.95 with the Bumpboxx Flare8 Pro does not make up for the sound-quality gap.
