Short answer: the Harman Kardon Go + Play 3 if sound quality matters most, the Bugani Brief Pro if price matters most. The Harman Kardon Go + Play 3 ranks #3 of 113 boombox speakers, rated 4.4/5, at $385. The Bugani Brief Pro ranks #28, rated 3.8/5, at $99.98, $285.02 cheaper.
Side by side, the Go + Play 3 wins. Reviewers found both crystal clear with good separation, but the Go + Play 3 has thicker, richer bass that reaches lower and holds up at every volume. The Brief Pro plays louder, but turns a little harsh and loses bass from about 80% volume.
Size and features: the Go + Play 3 is a three-way stereo design at 10.4 lbs (4.7 kg) with an aux input and a claimed 8 hours, and no water rating. The Brief Pro is a two-way design with a claimed 12 hours and Bluetooth 5.3.
The Brief Pro costs far less. The evidence on the Brief Pro is listening comparisons rather than measurements.
Buy the Harman Kardon Go + Play 3 if sound quality matters more than the price. Buy the Bugani Brief Pro if the price matters more than sound quality.
If water resistance matters to you, the Bugani Brief Pro at IPX5 (water jets) holds up far better than the Harman Kardon Go + Play 3 at no water resistance.
