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 85 boombox speakers, rated 4.4/5, at $385. The Bugani Brief Pro ranks #27, 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 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.

The Two Speakers In Full
Harman Kardon Go + Play 3: $385 Amazon eBay
Older model: the Harman Kardon Go + Play 2 (ranked lower, rated 3.9/5).
Pros: Warm sound with boosted bass. Deepest bass out of any speaker in this size. Sound is more natural than the Go + Play2. An aux input, a built-in microphone, a power bank function, stereo pairing and hidden button combinations for adjusting bass and treble. Measured bass extension of 35Hz (-10dB).
Cons: Just a little over half as loud as the higher rated boomboxes. Only 8 hours of battery at medium volume. No water rating.
Setup: Use the hidden EQ modes to adjust the bass up when outside and down when inside. To adjust bass, quickly press the bluetooth and volume down buttons together, the number of light flashes tell you what mode you’re in. To adjust treble, quickly press the volume up and phone buttons at the same time, the number of yellow flashes on the light tell you what mode you are in.

Bugani Brief Pro: $99.98 Amazon eBay
Pros: Crystal clear and detailed with good separation of instruments and vocals, impressive for a two-way layout of two 4” woofers and two 44mm tweeters on 80W RMS. It plays louder than the Harman Kardon Go + Play 3 and, in side by side sound tests, many listeners preferred it to the JBL Xtreme 4 and found it close to the EarFun UBoom X. A claimed 12 hours of battery, Bluetooth 5.3 and stereo pairing, at a low price.
Cons: It turns a little harsh and fatiguing at 80% to 100% volume while losing bass, and it doesn’t reach as deep as the Go + Play 3, which reviewers still preferred for its thicker, richer bass. Nothing so far shows how neutral its tuning is: the evidence is listening comparisons, not measurements. No published water rating.
