Short answer: the Bugani Brief Pro. It ranks #28 of 91 boombox speakers by sound quality, rated 3.8/5, at $99.98; the JBL Partybox On the Go ranks #60, rated 3.0/5, and costs $300, which makes this an easy call rather than a real tradeoff.
The Bugani Brief Pro is the better-sounding, longer-running choice. 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 is rated for 12 hours of battery against 6 for the JBL Partybox On the Go. The catch: 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.
Why pick the JBL Partybox On the Go: JBL Partybox On the Go uses 5.1” woofer + tweeters. The catch: Bass is limited by its 49Hz specification.
Buy the Bugani Brief Pro. It is rated higher for sound quality than the JBL Partybox On the Go and costs less, which makes it the one to get unless you need something the other one does better.

The Two Speakers In Full
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. No published water rating.

JBL Partybox On the Go: $300 Amazon eBay
Newer model: the JBL PartyBox On-The-Go 2 Plus, ranked higher, rated 4.4/5.
Pros: JBL Partybox On the Go uses 5.1” woofer + tweeters. Its 7.5 kg, claimed 6 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 94dB and limited-stereo playback make it a practical option for its intended room or portable use. A wireless microphone is included. Measured bass extension of 49Hz (-10dB).
Cons: Bass is limited by its 49Hz specification. No EQ adjustment. Battery life is short, and its sound trails the rest of the Partybox line.
