Sonos has long been the leader in multiroom audio, but now more brands are entering the space—some with features Sonos doesn’t offer.

Bose has recently entered the arena with its Lifestyle Ultra Speaker, which works similarly to Sonos’ smart speakers. Both brands sell standalone smart speakers that can operate independently throughout your home, be paired for stereo sound, or connected to a compatible soundbar to act as rear surround speakers.

Beyond the noticeable $130 price gap, there are key differences in ecosystem compatibility, smart capabilities, and voice assistant support. Here’s how they compare.

You should buy the Bose Lifestyle Ultra Speaker if…

1. You use Android devices

The Bose Lifestyle Ultra Speaker comes with built-in Google Cast—a major advantage for Android users or those with a mix of devices. Among the many smart speakers I’ve tested this year, very few include native Google Cast support.

Google Cast functions much like Apple AirPlay: it lets you send audio from your phone or tablet to the speaker, as long as both are on the same Wi-Fi network. I often use AirPlay to quickly route a YouTube video’s audio to a speaker, and switching back to my phone takes just seconds.

Keep in mind: although the Lifestyle Ultra Speaker supports Google Cast, it does not work with Google Assistant or Gemini.

2. You prefer not to use dedicated music apps

Most smart speaker makers rely on their own proprietary software platforms—like Sonos’ S2, Denon’s HEOS, or Apple’s walled garden. Bose took a different path, designing hardware that integrates smoothly with both iOS and Android.

Rather than providing a full-featured music streaming app, Bose’s app is limited to adjusting the speaker’s input source, setup, and equalizer settings. To play music, you simply stream directly from your device using Apple AirPlay, Spotify Connect, or Google Cast. This also means you can group the Bose Lifestyle Ultra Speaker with AirPlay- or Google Cast-compatible speakers from other brands for seamless multiroom audio.

You should buy the Sonos Era 100 if…

1. You plan to build a home theater system

One of Sonos’ biggest advantages is its wide selection of speakers across different sizes, performance levels, and price points—making it easier to create a custom home theater setup. Sonos currently offers three soundbars, two subwoofers, two rear speakers, and even headphones that work with its soundbars.

Plus, older Sonos products that are no longer sold still receive software updates and remain compatible.

This means you could start with just a soundbar and one Era 100 in another room. When you’re ready, add a second Era 100 and configure both as rear surround speakers. While Bose’s Lifestyle Ultra line works similarly, only the three products in that lineup are compatible with each other.

Importantly, Bose’s newest home theater gear isn’t backward compatible—for instance, you can’t pair your existing Bose Surround Speakers with the new Lifestyle Ultra Soundbar.

2. You’re deeply invested in Apple’s ecosystem

Sonos leans heavily toward Apple users, offering AirPlay support and direct access to Apple Music through the Sonos app. It doesn’t support Google Cast; instead, Sonos encourages streaming via its own app.

That said, if you subscribe to Apple Music, using the Sonos app unlocks Dolby Atmos playback. Although Apple announced in 2024 that iOS 18 would enable Dolby Atmos streaming to third-party speakers via AirPlay, this feature hasn’t been rolled out to Sonos devices yet. As of this writing, I’m unable to stream in Dolby Atmos to an Arc Ultra soundbar.

Writer’s choice

I’m not being indecisive—but really, the decision comes down to just two factors: price and ecosystem. Both speakers deliver a comparable V-shaped sound signature and support Amazon Alexa for voice control. If saving money is your top priority, the Sonos Era 100 is the better pick. If you value an open, flexible ecosystem, go with Bose.

Personally, I lean toward the Era 100 because I’m already in the Sonos ecosystem. The one on my kitchen counter responds to Sonos Voice Assistant commands and works seamlessly with my other Sonos speakers throughout the house.
