Short answer: the Sony ULT Field 7. It ranks #61 of 113 boombox speakers by sound quality (rated 3.2/5) at $448 and is still sold new; the Bumpboxx Flare 8 ranks #82 (rated 2.6/5) and is discontinued, so it is only an option used. The Bumpboxx Flare 8’s replacement, the Bumpboxx Flare8 Pro, is rated 2.8/5 at $449.
The Sony ULT Field 7 is the better-sounding, longer-running choice. A waterproof stereo party speaker with a 30 hour battery and karaoke mic and guitar inputs. It is rated for 30 hours of battery against 12 for the Bumpboxx Flare 8. At 13.9 lbs (6.3 kg) it weighs noticeably less than the Bumpboxx Flare 8 at 19 lbs (8.62 kg). It supports LDAC Bluetooth, which the Bumpboxx Flare 8 lacks. The catch: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Why pick the Bumpboxx Flare 8: A retro styled party speaker with FM radio, water resistance and high volume for small outdoor parties. The catch: Bass is thuddy rather than deep or controlled, and there is no app to improve the tuning.
Buy the Sony ULT Field 7. It is rated higher for sound quality, and the Bumpboxx Flare 8 is discontinued, so it is only available used.
