Short answer: both are discontinued, so this only matters if you are buying used. Used, the Bose Soundlink Mini 2 is the better pick: it ranks #72 of 175 medium speakers by sound quality (rated 3.4/5), 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 Bose Soundlink Mini 2 is the better-sounding pick. Compact aluminum build feels sturdy and dense. ~10 hour battery life; can pair to two devices at once and remembers up to 8. It plays in stereo from a single unit, unlike the Zealot S61. The tradeoff: Boosted upper bass like most Bose speakers.
The Zealot S61 is the longer-running, tougher 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 Bose Soundlink Mini 2. It is rated IPX7, while the Bose Soundlink Mini 2 has no water resistance. The catch: Sounds like a soup can, no bass at all.
Buy the Bose Soundlink Mini 2 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.
