Short answer: the Ultimate Ears Epicboom for better sound quality, the Zealot S67 for the lower price. The Ultimate Ears Epicboom ranks #57 of 77 large speakers at $213.41. The Zealot S67 ranks #76 at $80, $133.41 cheaper.
What the Ultimate Ears Epicboom offers: 17 hour battery with USB-C charging (first UE portable with USB-C). IP67 rating, floats in water. Made mostly from recycled fabric and plastic. Large best-sounding UE portable that still feels portable. 180ft Bluetooth range. Watch for: Not very deep bass for the size. Gets distorted at around 70-80% with bass thuds.
What the Zealot S67 offers: 60W output power, 20-hour battery life, IPX6 waterproof, Bluetooth 5.2, TWS stereo pairing, EQ with 3 sound modes, dual drivers with passive radiator, MicroSD and AUX support, built-in microphone, USB-C charging Watch for: A lot of distortion above 50%, no deep bass, rolled off treble. Just not a good sounding speaker.
Buy the Ultimate Ears Epicboom when sound quality outweighs the price for you, and the Zealot S67 when the price outweighs sound quality instead.
The Zealot S67 is not a sound-quality pick. It sits near the bottom of the 77 large speakers; there are better options higher up.
