Pros: Quite neutral sound, pretty deep bass.

Cons: A slight peak in the upper mids. Slight TWS issue where the 2nd is slightly delayed. Just as loud and slightly deeper bass than a Stormbox Blast which is way smaller with better sound quality. Discontinued.

Bose S1 Pro+: $699.00 Amazon eBay

Bose S1 Pro+ ranking card

Pros: Extremely compact and light with flexible placement options. Full sound with no lack of low-end output, crystal-clear audio quality. Three-channel mixer (2 XLR/quarter-inch combo mic-instrument + 1 line/Bluetooth), each with its own OLED display for quick treble/bass/reverb adjustment. Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode, plus a line out to daisy-chain a second unit. Optional WT-XLR/WT-INST wireless transmitters dock, pair, and charge right in the speaker for a cable-free mic or instrument. Up to 11 hours battery life. Professional build quality. High efficiency drivers reach 2-3x the volume of typical speakers for the same wattage.

Cons: With full range music, it becomes distorted above ⅔ volume, and reviewers describe it as screeching at max volume. Better suited for voice amplification. Not as much deep bass as the Everse 8, midrange sounds reasonably balanced. Treble is pretty boosted. Not stereo. Designed for more loudness than deeper bass. Ports are fully exposed with no water resistance. Charges via a less common three-prong AC cable instead of the two-prong barrel cable most rivals use.
