Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Boost “original model” pre-2021 is the better pick: it ranks #14 of 175 medium speakers by sound quality (rated 4.2/5), against #172 (rated 2.0/5) for the Zealot S61. If you want one new, the EarFun Uboom L ranks #2 at $49.79.
The Soundcore Boost “original model” pre-2021 is the better-sounding pick. At 1.3 lbs (590 g), Soundcore Boost “original model” pre-2021 combines 1.75” x 2 active drivers + passive radiator with Bluetooth and aux. It has an adjustable EQ, which the Zealot S61 lacks. It plays in stereo from a single unit, unlike the Zealot S61. The tradeoff: Careful placement is still important for balanced bass.
The Zealot S61 is the longer-running, tougher pick. 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 12 for the Soundcore Boost “original model” pre-2021. It is rated IPX7 against IPX5 for the Soundcore Boost “original model” pre-2021. It charges over USB-C rather than Micro USB. The catch: Sounds like a soup can, no bass at all.
Buy the Soundcore Boost “original model” pre-2021 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, start with the EarFun Uboom L instead.
