What the JBL Boombox 3 offers: IP67 rated. 24 hour battery life (6.5 hour charge time). Doubles as a power bank. PartyBoost links up to 100 compatible JBL speakers. Three-way speaker system with subwoofer. Watch for: Dips in mid bass range which makes the bass sound undefined, bass boosted, peaky at 700hz, not quite as good mids and treble as the Blast.
What the Yeahbox Sonic Boom Max 3 offers: A large 3-way, 5-driver party speaker with claimed 200W RMS output, a 111Wh battery, USB-C fast charging, app EQ, TWS pairing, and aux, USB and microSD playback. Listener comparisons describe powerful bass, strong output and decent mids and highs for outdoor party use. Watch for: There is limited independent testing and the water/dust rating is reported inconsistently across listings. Listener comparisons find it less clear and refined than stronger boombox rivals, so its big bass and output are a better fit for parties than critical listening.
