Short answer: the Encore Essential 2 for off axis sound, the Boombox 3 for battery and ruggedness. The Essential 2’s dome tweeters over cone appear better off axis, though it is missing a little bit of upper bass. The Boombox 3 is IP67 rated with 24 hour battery life and doubles as a power bank, but a mid bass dip makes its bass sound undefined, it is bass boosted and peaky at 700Hz, and its mids and treble are not quite as good as the Blast.
Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality than the JBL Boombox 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
Battery life favors the JBL Boombox 3: rated for 24 hours against 15 hours for the JBL Partybox Encore Essential 2.
There is a real gap in water resistance: the JBL Boombox 3 at IP67 (brief submersion) against the JBL Partybox Encore Essential 2, which has IPX4 (splashing).

The Two Speakers In Full
JBL Partybox Encore Essential 2: $219.00 Amazon B&H Photo Video eBay
Older model: the JBL Partybox Encore Essential (ranked lower, rated 4.2/5).
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. Measured bass extension of 42Hz (-10dB).
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.
