These sit in different size classes, so this is not a straight ranking comparison. The Xiaomi Sound Party ranks #20 of 179 medium speakers by sound quality at $135.84; the Marshall Middleton ranks #33 of 120 large speakers by sound quality at $257.52.
The Xiaomi Sound Party is the louder, longer-running choice. A versatile outdoor speaker with warm, balanced sound, fully waterproof build, long battery life, a phone charging port and a handy retractable handle. Alan Ross Reviews measured it at 102dB at full volume, against 99dB for the Marshall Middleton. It is rated for 26 hours of battery against 20 for the Marshall Middleton. At 2.6 lbs (1.2 kg) it weighs noticeably less than the Marshall Middleton at 4 lbs (1.8 kg). Watch for: The sound evidence is mixed rather than universally glowing.
The Marshall Middleton is the deeper-bass option. A waterproof stereo speaker with very deep bass for its size, a long battery, a power bank and a detachable strap. Its bass reaches about 39Hz before falling 10dB, against 54Hz for the Xiaomi Sound Party. It keeps a wired aux input, which the Xiaomi Sound Party lacks. It plays in stereo from a single unit, unlike the Xiaomi Sound Party. Watch for: 5db dip at 1.7kHz and 6.3kHz.
Buy the Xiaomi Sound Party ($135.84) for a medium speaker; the Marshall Middleton ($257.52) suits a large speaker instead.
