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. Note, JBL daisychain is not compatible with any other non-JBL speaker and is possibly a fully digital signal. Discontinued.

Bose S1 Pro: $699.00 Discontinued Amazon

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 mic/line + 1 line/Bluetooth). Auto EQ adjusts sound based on orientation. Multiple angled surfaces for various positioning including tilted portrait mode. 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. 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. Discontinued.
