Short answer: the DOSS Extreme Boom, if you are buying new. The Dockin D Fine ranks higher than it (#36 vs #121 of 126 large speakers, 3.9/5 vs 2.1/5) but is discontinued, so only consider it used; the DOSS Extreme Boom is still sold new at $75.99.
The Dockin D Fine is the better-sounding, lighter option. A stereo speaker with clear, natural vocals and controlled bass, plus an aux input and a power bank output. At 4.3 lbs (1.93 kg) it weighs noticeably less than the DOSS Extreme Boom at 5.6 lbs (2.52 kg). The tradeoff: It is discontinued, so condition and support matter more than its original specifications.
The DOSS Extreme Boom is the longer-running option. An affordable waterproof outdoor speaker with a long rated battery, power bank output, and bass heavy sound for casual parties. It is rated for 30 hours of battery against 10 for the Dockin D Fine. The catch: The measured 65Hz -10dB bass point means it lacks true low bass despite its boomy voicing.
Buy the DOSS Extreme Boom new; the Dockin D Fine is no longer sold new, so it only makes sense as a used find.
