Short answer: the W-King X20. It ranks #43 of 112 boombox speakers by sound quality (rated 3.5/5) at $219.98 and is still sold new; the Bumpboxx Flare 6 ranks #82 (rated 2.6/5) and is discontinued, so it is only an option used.
The W-King X20 is the better-sounding, longer-running choice. A loud stereo party speaker with a large subwoofer, a 24 hour battery with power bank, and water resistance. It is rated for 24 hours of battery against 12 for the Bumpboxx Flare 6. It has an adjustable EQ, which the Bumpboxx Flare 6 lacks. The tradeoff: Rising frequency response but upper treble rolled off, 700Hz and 1.2kHz peaks.
Why pick the Bumpboxx Flare 6: A retro styled stereo party speaker with water resistance and a 12 hour battery. The tradeoff: There is no companion app.
Buy the W-King X20. It is rated higher for sound quality; the Bumpboxx Flare 6 is no longer sold new.
