Short answer: both are discontinued, so this only matters if you are buying used. Used, the JBL Flip Essential is the better pick: it ranks #90 of 175 medium speakers by sound quality (rated 3.2/5), against #172 (rated 2.0/5) for the Zealot S61. If you want one new, the JBL Flip Essential 3 SE replaces the JBL Flip Essential and is rated 3.6/5 at $113.82.
The JBL Flip Essential is the better-sounding, lighter pick. A genuinely portable 1 lbs (471 g) speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. At 1 lbs (471 g) it weighs noticeably less than the Zealot S61 at 1.5 lbs (665 g). The catch: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight.
The Zealot S61 is the longer-running choice. 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 1.5 lbs (665 g) design, single full-range driver, built-in microphone, AUX input, USB-C charging. It is rated for 40 hours of battery against 10 for the JBL Flip Essential. It charges over USB-C rather than Micro USB. The catch: Sounds like a soup can, no bass at all.
Buy the JBL Flip Essential only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the JBL Flip Essential 3 SE, which replaces the JBL Flip Essential.

The Two Speakers In Full
JBL Flip Essential: $130 Discontinued eBay
Newer model: the JBL Flip Essential 3 SE, ranked higher, estimated 3.6/5, released Apr 2026. See every JBL Flip Essential generation.
Pros: A genuinely portable 471g speaker with IPX7 water resistance, a 3.5mm aux input and 16W output from two full-range drivers. It is a simple, no-app option for wired sources, travel and casual listening where its cylindrical shape and modest size are a genuine advantage.
Cons: Bass is lighter than the JBL Flip 5 and the 80Hz claimed low-frequency limit means it cannot deliver real low-end weight. Battery life is only a claimed 10 hours, there is no speakerphone, EQ or party mode, and its older Bluetooth 4.1 platform and discontinued status make it a basic used-market choice.
