JBL Partybox Encore Essential 2 vs onn Pro X Large Boom Boombox

Why pick the JBL Partybox Encore Essential 2: 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. The tradeoff: 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.

Why pick the onn Pro X Large Boom Boombox: High rated power for the price at 180W RMS (540W peak). The tradeoff: Bass not as deep as higher ranked speakers like the JBL Boombox 3, JBL Boombox 4, or Tribit Stormbox Blast.

Buy the JBL Partybox Encore Essential 2. It is rated higher for sound quality, and saving $60 with the onn Pro X Large Boom Boombox does not make up for the sound-quality gap.

If water resistance matters to you, the onn Pro X Large Boom Boombox at IP67 (brief submersion) holds up far better than the JBL Partybox Encore Essential 2 at IPX4 (splashing).

Older model: the JBL Partybox Encore Essential (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.

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.
