These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Citation 200 ranks #13 of 117 large speakers by sound quality at $130; the Sonos Era 100 ranks #16 of 29 powered desktop speakers by sound quality at $217.99.
The Harman Kardon Citation 200 is the battery-powered, tougher option. A portable smart speaker with Wi-Fi, Google Assistant and deep bass for its size, now discontinued but worth buying used. Its battery is rated for 8 hours, while the Sonos Era 100 needs an outlet. It is rated IPX4, while the Sonos Era 100 has no water resistance. The tradeoff: Overly boomy by default, you can short press the Bluetooth and volume down buttons simultaneously to decrease the bass, and the Bluetooth and volume up buttons simultaneously to increase it.
The case for the Sonos Era 100: A compact Wi-Fi smart speaker with stereo from two angled tweeters, Trueplay room tuning, Alexa and Sonos multiroom. It links with other speakers (Sonos multi-room, AirPlay 2), which the Harman Kardon Citation 200 cannot. It has an adjustable EQ, which the Harman Kardon Citation 200 lacks. The tradeoff: RTINGS’ own two listed cons are not loud enough for larger rooms and very little low-bass thump, so genres like EDM and hip-hop lack rumble even with the tone adjustments.
Worth knowing: the Harman Kardon Citation 200 is discontinued, though it still ranks #13 of 117 large speakers by sound quality, so a used unit beats most of what is still sold new.
Buy the Harman Kardon Citation 200 at $130 for a large speaker, or the Sonos Era 100 at $217.99 for a powered desktop speaker instead.
