Short answer: the Yeahbox Sonic Boom Max 3. It ranks #40 of 75 boombox speakers by sound quality at $228.99; the Bumpboxx Flare 6 ranks #58 and costs $300, so there is little reason to consider the other one.
What the Yeahbox Sonic Boom Max 3 offers: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use. Watch for: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
What the Bumpboxx Flare 6 offers: At 5.9 kg, Bumpboxx Flare 6 combines 6” woofer + tweeters with Bluetooth. Claimed 12 hours (manufacturer specified) battery life, ipx6 protection, up to 115db and stereo playback make its feature set practical for its intended room or portable use. Watch for: There is no companion app. No EQ adjustment.
Buy the Yeahbox Sonic Boom Max 3. It ranks higher for sound quality than the Bumpboxx Flare 6 and costs less, which settles it without a real tradeoff to make.
If sound quality matters at all to you, skip the Bumpboxx Flare 6. It ranks near the bottom of the 75 boombox speakers, so look higher up the list instead.
