These are not really the same size class, and that is the honest framing here. The JBL Authentics 500 ranks #3 of 5 powered desktop speakers by sound quality at $600; the Sonos Roam 2 ranks #74 of 142 medium speakers by sound quality at $179.
The case for the JBL Authentics 500: JBL Authentics 500 uses 6.5” (down-firing subwoofer), 3x 2.75” midranges, 3x 1” (25mm aluminum dome) tweeters. The tradeoff: Its 40Hz - 20kHz (-6dB) (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
The case for the Sonos Roam 2: Very neutral. The tradeoff: Exact same sound quality as the original Roam.
Buy the JBL Authentics 500 ($600) for a powered desktop speaker; the Sonos Roam 2 ($179) suits a medium speaker instead.
If water resistance matters to you, the Sonos Roam 2 at IPX5 (water jets) holds up far better than the JBL Authentics 500 at no water resistance.
