Yeahbox Sonic Boom Max 3: $228.99 Amazon eBay
Pros: 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.
Cons: 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.
