Doss Extreme Boom vs Zealot S67

Last updated: August 18, 2026

Short answer: the Doss Extreme Boom. It ranks #75 of 77 large speakers by sound quality at $69.99; the Zealot S67 ranks #76 and costs $80, so there is not much of a tradeoff to weigh.

On the Doss Extreme Boom side: 60W output power, exceptional 30-hour battery life, power bank function, IPX7 waterproof, MicroSD card support, dual drivers with passive radiator, TWS stereo pairing, USB-C charging, built-in microphone. Set against that: Rolled off treble, barely any bass.

The case for the Zealot S67: 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. The tradeoff: A lot of distortion above 50%, no deep bass, rolled off treble.

Buy the Doss Extreme Boom. It ranks higher for sound quality than the Zealot S67 and costs less, so there is no real case for the other one.

If sound quality matters at all to you, skip both of these and look higher up the 77 large speakers instead.

If battery life is a priority, the Doss Extreme Boom is rated for 30 hours versus 20 hours for the Zealot S67.
