These are not really the same size class, and that is the honest framing here. The Bugani Brief Pro ranks #28 of 113 boombox speakers by sound quality at $99.98; the JBL Xtreme 4 ranks #43 of 120 large speakers by sound quality at $309.95.
Different sizes. The Brief Pro is a boombox with two 4” woofers and two 44mm tweeters. The Xtreme 4 is a large 4.6 lbs (2.1 kg) speaker. Each is rated within its own class.
In a side by side sound test, listeners in the comments preferred the Brief Pro’s bigger, clearer sound, which comes from larger drivers. The Xtreme 4 measured about 106dB and benefits from its app EQ.
Toughness and features favor the JBL: IP67, a replaceable battery, a power bank output and Auracast. The Brief Pro has no published water rating. The evidence on the Brief Pro is listening comparisons rather than measurements.
Buy the Bugani Brief Pro at $99.98 for a boombox speaker, or the JBL Xtreme 4 at $309.95 for a large speaker instead.
If battery life is a priority, the JBL Xtreme 4 is rated for 24 hours versus 12 hours for the Bugani Brief Pro.
