Looking for a cheaper alternative to the Sonos Era 300? It usually sells for about $499. Here are 4 cheaper swaps from $219: the Marshall Stanmore III is the closest match from another brand and the Sonos Era 100 is a cheaper option from Sonos. Each one says what you give up for the lower price.
The Sonos Era 300 costs $499. A cheaper pick for Apple users is the Apple HomePod (2nd generation) at $349, which also plays spatial audio. The cheapest Sonos option is the Era 100 at $219.
The Sonos Era 300 ($499) is worth it if you want Dolby Atmos music from a single speaker and already use, or plan to build, a Sonos system. Sonos lists six drivers, including an upward-firing tweeter that bounces sound off the ceiling and two woofers angled left and right, plus Wi-Fi 6, Bluetooth 5.3, AirPlay 2 and line-in through a separately sold USB-C adapter. In Gear Patrol's comparison with Apple's HomePod, the Era 300 sounded warmer, clearer and more immersive and played significantly louder.
If you live in Apple's ecosystem, the Apple HomePod (2nd generation) ($349) has Spatial Audio with Dolby Atmos and room sensing, and Gear Patrol narrowly preferred it for iPhone and Apple Music users. If you want the Sonos app and multiroom system without Atmos, the Sonos Era 100 ($219) has two angled tweeters, a midwoofer, Bluetooth 5.3 and AirPlay 2. The Amazon Echo Studio (2025) ($220) adds Dolby Atmos and a Zigbee, Matter and Thread smart home hub for Alexa homes, and the Marshall Stanmore III ($400) suits people who want a large Bluetooth speaker with RCA and 3.5mm inputs and no Wi-Fi.

The Sonos Era 100, at about $219 (56% less). Stereo sound, Bluetooth, AirPlay 2 and the same Sonos app and multiroom; line-in works with a separate adapter. The catch: No spatial audio or Dolby Atmos, and a smaller sound than the Era 300.
The Marshall Stanmore III, at about $400 (20% less). A large home speaker with room-filling sound and RCA and 3.5mm inputs. The catch: Bluetooth only, with no Wi-Fi, spatial audio or Sonos multiroom.
Apple's HomePod (2nd generation) is $349 and supports spatial audio with room sensing. Sonos's own Era 100 is $219 with stereo sound, Bluetooth and AirPlay 2.
Yes. It has Bluetooth, and line-in works through Sonos's separate USB-C Line-In Adapter.
Sonos support lists Amazon Music and Apple Music for Dolby Atmos Music on the Era 300; TIDAL's Atmos preview is limited to Arc and Arc Ultra. Gear Patrol found Atmos tracks have to be played from the Sonos app, because AirPlay and Bluetooth can't carry them.
No. Sonos lists Sonos Voice Control and Amazon Alexa as the voice options for the Era 300, and Gear Patrol confirms it does not support Google Assistant. Sonos notes that availability of each assistant varies by language and country.
In Gear Patrol's comparison, the Era 300 was louder and more immersive thanks to its upward-firing tweeter, while the HomePod relies on computational audio to suggest height. Gear Patrol still narrowly picked the HomePod for iPhone and Apple Music users, and recommended the Era 300 for people set on Atmos from Apple Music or Amazon Music Unlimited who don't mind the Sonos app.

Every swap is a product sold in the US that does the main job of the original. Close match is another brand with similar features, Same brand, cheaper is an older, smaller or renewed model from the same maker, and Budget pick is the cheapest thing that still does the job. On each page, Closest match is the close match nearest the original in price, and Lowest price is the cheapest swap. We compare published specs, retailer listings and reviews; we don't test products ourselves.
A cheaper product is cheaper for a reason. Each swap says what you give up, like weaker noise cancelling, a smaller screen or a shorter warranty, so you can decide if the savings are worth it.
