Pros: Included wireless microphone.

Cons: Poor water rating. Horrible battery life. Probably the worst sounding of the Partybox line. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal.

Soundcore Motion Boom+: $140 after $40 coupon, Discontinued Amazon

Soundcore Motion Boom+ ranking card

Pros: 80W stereo from dual 30W woofers + dual 10W tweeters with titanium drivers for treble clarity. 13,400mAh battery for 20 hours (12-15 at high volume). IP67 waterproof, floats, rugged build inspires confidence. Bluetooth 5.3 multipoint pairing, Soundcore app EQ, PartyCast 2.0 mode. USB-C input, USB-A output for powerbank.

Cons: Default presets are all warm sounding with rolled off treble. Will need a custom EQ to get closer to neutral. A shrill sounding 6khz peak comes out when volume is above about 60%. Not much deeper bass than a Motion Boom and a lot less deep bass than other speakers in the class. Discontinued.
