Short answer: the JBL Partybox Encore Essential 2 for off axis sound, though the Yeahbox Sonic Boom Max 3 promises more hardware. The Essential 2’s dome tweeters over cone appear better off axis, though it is missing a little bit of upper bass. The Sonic Boom Max 3 pairs 200W RMS and 300W peak with a true 3-way, 5-driver array, but it is a budget brand with limited independent testing and manufacturer-claimed specs.
What the JBL Partybox Encore Essential 2 gets right: Appears to have better off axis performance due to the move to dome tweeters over cone. Set against that: Missing a little bit of upper bass.
On the Yeahbox Sonic Boom Max 3 side: 200W RMS (300W peak) true 3-way, 5-driver array. The catch: A budget import brand with limited independent testing - specs are manufacturer-claimed.
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality, and the $48.03 you would save on the Yeahbox Sonic Boom Max 3 does not close the gap.

The Two Speakers In Full
JBL Partybox Encore Essential 2: $254.12 Amazon B&H Photo Video eBay
Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior.
Cons: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

Yeahbox Sonic Boom Max 3: $206.09 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.
