Short answer: the Marshall Middleton II for bass depth, the Soundcore Motion Boom for a cleaner midrange. The Middleton II has very deep bass for its size and weight, but that boost drowns out the midrange, with a dip around 200Hz, a peak at 1kHz and a dip at 1.6kHz. The Boom runs 30W of loud, bass-heavy sound with a 10,000mAh battery claimed for 24 hours, 15 to 18 with BassUp at high volume.
Buy the Marshall Middleton II, since the Soundcore Motion Boom is discontinued and only worth hunting down used.
