Short answer: the JBL Xtreme 4. It ranks #40 of 85 large speakers by sound quality, rated 3.8/5, at $309.95. The Doss Extreme Boom ranks #83, rated 2.1/5, at $79.99, $229.96 cheaper, not enough of a saving to outweigh the sound-quality gap.
Why pick the JBL Xtreme 4: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. The tradeoff: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
Why pick the Doss Extreme Boom: A durable 2.52kg outdoor speaker with claimed 60W output, IPX7 protection, USB-C charging, aux and microSD playback, speakerphone capability, a power bank and TWS pairing. Watch for: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the JBL Xtreme 4. It is rated higher for sound quality, and saving $229.96 with the Doss Extreme Boom does not make up for the sound-quality gap.

The Two Speakers In Full
JBL Xtreme 4: $309.95 Amazon B&H Photo Video eBay
Newer model: the JBL Xtreme 5, ranked higher, rated 4.6/5.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.

Doss Extreme Boom: $79.99 Amazon eBay
Pros: A durable 2.52kg outdoor speaker with claimed 60W output, IPX7 protection, USB-C charging, aux and microSD playback, speakerphone capability, a power bank and TWS pairing. It offers long claimed battery life and can play loudly enough for a casual party, with a bass-heavy sound that carries outdoors. Measured bass extension of 65Hz (-10dB).
Cons: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing. Reviews describe fuzzy mids, mushy bass when pushed and rolled-off treble, while there is no app or EQ to restore balance. It is best for loud background music, not clear or refined listening.
