Short answer: the Motion Boom, and it’s cheaper too. It ranks #14 of 120 large speakers at $109.99; the D Fine+ 2 ranks #29 at $150, $40.01 more. The Soundcore Motion Boom has been replaced by the Soundcore Boom 2. If you are buying new, get the Soundcore Boom 2.
The D Fine+ 2’s real strength is bass depth for its category. Our notes credit it with quite deep bass, though clarity through the midrange trails the top-ranked speakers, with a specific dip noted at 1.8kHz.
The Motion Boom is the budget benchmark of this class. Our notes call it excellent budget-friendly value, with a genuine 24-hour battery and a buoyant waterproof design, and its only real knock is being less neutral and detailed than the top of the class.
Buy the Motion Boom for the better value and higher ranking. Buy the D Fine+ 2 if its specific bass character is what you’re after.
Battery life favors the Soundcore Motion Boom: rated for 24 hours against 16 hours for the Dockin D Fine+ 2.
