Short answer: both are discontinued, so this only matters if you are buying used. Used, the Soundcore Rave Party 2 is the better pick: it ranks #64 of 112 boombox speakers by sound quality (rated 3.1/5), against #76 (rated 2.8/5) for the Diamondboxx M3. If you want one new, the Tribit Stormbox Blast ranks #2 at $179.99.
The Soundcore Rave Party 2 is the better-sounding, tougher choice. A stereo party speaker with LED lights, a karaoke mic input and linking for up to 100 speakers. It is rated IPX4, while the Diamondboxx M3 has no water resistance. It links with other speakers (PartyCast 2.0 up to 100 speakers), which the Diamondboxx M3 cannot. It has an adjustable EQ, which the Diamondboxx M3 lacks. The catch: Only IPX4 splash resistance, and bass extension seems limited.
The Diamondboxx M3 is the longer-running pick. A compact, very loud boombox with a powerful amplifier and a choice of large battery packs. It is rated for 40 hours of battery against 16 for the Soundcore Rave Party 2. Watch for: Despite its output, bass does not reach as deep as the best large portables and can distort when pushed hard.
Buy the Soundcore Rave Party 2 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Tribit Stormbox Blast instead.
