Short answer: the Marshall Emberton II if sound quality matters most, the Zealot S61 if price matters most. The Marshall Emberton II ranks #100 of 136 medium speakers at $160.23. The Zealot S61 ranks #134 at $20, $140.23 cheaper.
What the Marshall Emberton II offers: 30 hour battery life - among the best in its class; a 20 min quick-charge gives 4 hours. IP67 rated, durable rubbery build using 50% recycled plastic. Watch for: Strange unnatural echo-like sound coloration, bass not as deep as competitors. Not technically a 360 speaker, only front and rear. Not very loud.
What the Zealot S61 offers: 20W output, IPX7 waterproof, exceptional 40-hour battery life, Bluetooth 5.2, TWS stereo pairing, compact 665g design, single full-range driver, built-in microphone, AUX input, USB-C charging Watch for: Sounds like a soup can, no bass at all. Weird frequency response all over.
Buy the Marshall Emberton II if sound quality matters more than the price. Buy the Zealot S61 if the price matters more than sound quality.
The Zealot S61 is not a sound-quality pick. It sits near the bottom of the 136 medium speakers; there are better options higher up.
