Short answer: the Doss Extreme Boom, if you are buying new, though neither ranks well in its class. The Hopestar A6 Pro ranks higher than it (#80 vs #83 of 85 large speakers, 2.3/5 vs 2.1/5) but is discontinued, so only consider it used; the Doss Extreme Boom is still sold new at $79.99. Both are rated below 3.0/5 among the 85 large speakers, and the Tribit Stormbox Lava, ranked #3 at $100, is a better place to start if sound quality matters.
The case for the Hopestar A6 Pro: Powerful 34W output, built-in microphone for hands-free calling, IPX6 water resistant, power bank function, MicroSD card support. The tradeoff: No dynamics, sounds very hollow, no deep bass.
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. The tradeoff: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the Doss Extreme Boom if you want one new; the Hopestar A6 Pro is discontinued, so only look for it used.

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.
