These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Citation 200 ranks #13 of 78 large speakers by sound quality at $130; the Sonos Era 300 ranks #4 of 5 powered desktop speakers by sound quality at $499.
The case for the Harman Kardon Citation 200: Deeper bass than any Onyx. 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 300: RTINGS calls it an excellent choice for voice assistants: built-in Alexa has no trouble hearing commands from a distance or in a noisy room, with a mic mute button on the back. The tradeoff: RTINGS’ one listed con is some compression at max volume.
Buy the Harman Kardon Citation 200 at $130 if you want a large speaker. Buy the Sonos Era 300 at $499 if you want a powered desktop speaker instead.
There is a real gap in water resistance: the Harman Kardon Citation 200 at IPX4 (splashing) against the Sonos Era 300, which has no water resistance.

Sonos Era 300: $499.00 each Amazon eBay
Pros: RTINGS calls it an excellent choice for voice assistants: built-in Alexa has no trouble hearing commands from a distance or in a noisy room, with a mic mute button on the back. Six drivers, one forward-firing tweeter, two side-firing tweeters, one upward-firing tweeter, and two angled woofers, each with its own Class D amp, give real stereo separation plus Dolby Atmos spatial audio on supported content. Trueplay room correction (now including a quicker Android tuning option) is a genuine strength, and it pairs with Sonos soundbars like the Arc Ultra for a home theater setup.
Cons: RTINGS’ one listed con is some compression at max volume. Out of the box the tuning leans bass-heavy enough that vocals can get shrouded in the mix on some tracks, though Trueplay largely corrects this. There’s no Google Assistant, no battery, and at $499 it’s the most expensive speaker in this ecosystem comparison.
