Short answer: the Sonos Era 100. It ranks #16 of 28 powered desktop speakers by sound quality, rated 3.6/5, at $219; the Harman Kardon Aura Studio 5 ranks #21, rated 3.5/5, and costs $295.99, which makes this an easy call rather than a real tradeoff.
The case for the Harman Kardon Aura Studio 5: Proper 3-way design with a 143mm subwoofer, six midrange drivers and a dedicated tweeter, rated to 45Hz at -6dB, so it fills a room evenly with real low end. Watch for: Mains powered home speaker with no battery, no aux input and no Wi-Fi streaming in this version.
Why pick the Sonos Era 100: It plays in stereo from a single unit, unlike the Harman Kardon Aura Studio 5. Watch for: 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.
Buy the Sonos Era 100. It is rated higher for sound quality than the Harman Kardon Aura Studio 5 and costs less, which makes it the one to get unless you need something the other one does better.
Worth knowing: the Harman Kardon Aura Studio 5 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.1 to 3.8, so treat this verdict as provisional.

The Two Speakers In Full
Harman Kardon Aura Studio 5: $295.99 each Estimated Amazon $295.99 eBay
Pros: Proper 3-way design with a 143mm subwoofer, six midrange drivers and a dedicated tweeter, rated to 45Hz at -6dB, so it fills a room evenly with real low end. Striking transparent dome with music synced and projected lighting, Bluetooth 5.4, Auracast multi speaker linking, stereo pairing and app EQ.
Cons: Mains powered home speaker with no battery, no aux input and no Wi-Fi streaming in this version. The 360 degree layout and bass forward tuning favor ambience over precise imaging. Expensive for a Bluetooth only speaker at $296, and there is no independent measurement yet.

Sonos Era 100: $219.00 each Amazon $219.00 eBay
Same family: the Sonos Era 300 (larger model, rated 4/5).
Pros: RTINGS lists room correction tools and bass/treble adjustments as its real strengths, and its balanced midrange suits a wide range of genres, with wider stereo separation than the mono Sonos One SL it replaced thanks to two angled tweeters plus a 25% larger mid-woofer than the original Sonos One. Alexa is built in with a far-field mic, and it ties into the wider Sonos S2 app ecosystem for multi-room audio.
Cons: 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. There’s no Google Assistant, the USB-C line-in needs a separately purchased adapter, and there’s no battery.
