AI Verdict
The Sonos Era 100 is a fantastic-sounding compact speaker for upgrading a room or starting a Sonos system, but the lack of Google Assistant and extra costs for basic connections are frustrating.
The Era 100 is a strong fit for those already in the Sonos ecosystem or starting fresh and prioritizing sound quality, thanks to its stereo sound and improved bass. However, the lack of Google Assistant and the need to buy a separate adapter for a basic line-in connection make it a less ideal choice for users outside the Apple/Alexa ecosystems or those expecting all features out of the box.
If you need a speaker that supports Dolby Atmos and more immersive spatial audio, you'll need to upgrade to a model like the Sonos Era 300.

Pros
- Dual-tweeter design produces a legitimate stereo soundstage from a single speaker.
- The 25% larger midwoofer delivers noticeably deeper and richer bass than the Sonos One.
- Finally includes Bluetooth 5.0, making it easy for guests to connect without Wi-Fi.
- Setup is extremely fast, taking just a few minutes through the Sonos app.
- Features a USB-C port that supports line-in for turntables or other devices, via an adapter.
Cons
- Line-in connectivity requires a proprietary Sonos adapter that is sold separately.
- Full Trueplay room tuning, a key audio feature, is only available using an iOS device.
- No longer supports Google Assistant, only Amazon Alexa and Sonos Voice Control.
- Cannot be stereo paired with an older Sonos One speaker; you must use another Era 100.
- Some users report the bass can be overpowering and resonate through furniture without EQ adjustments.
Dimension Scores
The dual-tweeter architecture creates a wide stereo soundstage from a single box, which is a clear upgrade over most mono speakers in its class.
A 25% larger midwoofer provides deep, rich bass for its size, though some users find it can be overpowering without EQ adjustments.
It offers Wi-Fi, AirPlay 2, and finally Bluetooth, but requiring a proprietary, sold-separately adapter for a simple 3.5mm line-in is a significant drawback.
The speaker has a solid, premium feel and compact design, but it's a corded, 4.45-pound speaker that is not designed to be portable.
Best For
- Expanding an existing Sonos multi-room audio system into a bedroom or kitchen.
- Use as high-quality rear surround speakers for a Sonos Arc or Beam soundbar.
- A primary smart speaker for users who prefer Amazon Alexa and stream music over Wi-Fi.
- Connecting a turntable or CD player to the Sonos ecosystem (with the purchase of the adapter).
Not Recommended For
- Android-only households who want the most advanced room-tuning capabilities.
- Users who rely on Google Assistant for smart home control and voice commands.
- Anyone needing a portable, battery-powered speaker for outdoor use.
Watch Out For
- The USB-C port doesn't work with standard 3.5mm adapters for line-in; you must buy the specific Sonos adapter.
- Trueplay room tuning is a major selling point, but the most effective 'Advanced Tuning' version only works if you have an iPhone or iPad.
- If you have a Sonos One, you can't buy an Era 100 to create a stereo pair; they are incompatible for pairing.
- Google Assistant is not supported, a feature that was available on the previous generation Sonos One.

What Buyers Say
The most surprising thing people find with the Era 100 is the genuine stereo separation from a single, compact speaker—it's a massive step up from the mono Sonos One. The bass is consistently described as deeper and more powerful, making it sound larger than it is. Setup is almost universally praised as taking only a few minutes via the Sonos app. The biggest recurring complaints are about the hidden costs and feature removals; you have to buy a specific Sonos adapter to connect a turntable, and Google Assistant support, present in the previous generation, has been completely removed. Android users also frequently complain that the 'Trueplay' tuning feature is a less effective 'quick' version compared to the full tuning on an iPhone.
“the sound is incredible and way better than my old One but im so annoyed that i have to buy a special dongle just to plug in my turntable, seriously sonos??”
Common Praise
- The stereo sound from one speaker is surprisingly wide and immersive.
- Finally having Bluetooth makes it so much easier for friends to play music without app access.
- The bass is much richer and deeper compared to the Sonos One, without getting distorted at high volumes.
- Setup is incredibly simple and fast, going from unboxing to playing music in under five minutes.
- The new volume slider on the top is more intuitive than the old tap buttons.
- Works great as rear surround speakers in a Sonos home theater, offering much more clarity than older models.
Common Complaints
- Having to pay extra for a proprietary adapter to use the line-in port feels like a cash grab.
- The removal of Google Assistant support is a dealbreaker for those invested in the Google ecosystem.
- The full, effective Trueplay room tuning only works with an iPhone or iPad.
- You can't create a stereo pair with an existing Sonos One, forcing you to buy two new speakers.
- The default bass level can be too boomy and requires turning it down in the EQ settings.
- There's a noticeable audio delay when using the line-in for video sources like a computer or TV.
Ownership Tips
- The black matte finish looks great but is a magnet for dust and fingerprints.
- If you have an Android, it's genuinely worth borrowing a friend's iPhone for 10 minutes to run the 'Advanced' Trueplay tuning; the difference is noticeable.
- The top status light can be disabled in the app, which is a must-have feature for use in a bedroom.
- Sonos Voice Control is fast for music commands but doesn't support Spotify or YouTube Music, pushing you to use Alexa for those services.
- The speaker can sound very different depending on placement; placing it near a wall significantly boosts the bass, for better or worse.
Frequently Asked Questions
Can I use any USB-C to 3.5mm adapter for the line-in?
No, you must use the proprietary Sonos Line-In Adapter for it to work. Standard adapters that convert digital-to-analog won't function for the analog-to-digital conversion the speaker requires.
Does the Sonos Era 100 support Google Assistant?
No, it does not have Google Assistant built-in. It only supports Amazon Alexa and Sonos Voice Control.
Can I make a stereo pair with my old Sonos One?
No, you cannot. A stereo pair requires two of the same type of speaker, so you must use two Era 100s.
Is the Era 100 portable?
No, it does not have a built-in battery and must be plugged into a power outlet to function.
Do I need an iPhone for Trueplay tuning?
For the best result ('Advanced Tuning'), yes, you need an iOS device. Android users have access to a 'Quick Tuning' method that uses the speaker's own microphones, but it is considered less precise.
Is the sound a big improvement over the Sonos One?
Yes, most users report a significant improvement. The Era 100 offers stereo sound from a single unit and has a 25% larger woofer for much deeper bass.
Can I use the Era 100 as a computer speaker?
You can, but there can be a noticeable audio delay even when using the line-in adapter on its lowest setting (75ms). Some users also report connection dropouts when used as a stereo pair near a computer setup.
Buying Guide
When you buy a Sonos speaker, you're not just getting a speaker, you're getting a piece of a whole-home audio system. The Era 100 is great on its own, but it's designed to work with other Sonos products over Wi-Fi. Think about how you'll use it: if you mainly stream from services like Spotify or Apple Music, the experience is seamless. The new Bluetooth is a huge plus for guests. But if your main plan is to connect a turntable, you MUST factor in the extra cost of the Sonos Line-In adapter.
speaker_type: Multi Room
This means the speaker connects to your Wi-Fi and can sync perfectly with other Sonos speakers throughout your house. You can play the same song everywhere for a party, or have different music in each room, all controlled from one app.
connectivity: Bluetooth, USB, Wi-Fi
Wi-Fi gives you the highest quality sound and multi-room control. Bluetooth is a simple, direct connection from your phone to the speaker, no app needed. The 'USB' is a USB-C port that ONLY works for the special Sonos adapters for line-in or an Ethernet cable; you can't plug in a flash drive.
audio_mode: Surround
This means you can use two Era 100 speakers as the back-left and back-right channels in a home theater setup. They wirelessly connect to a Sonos soundbar (like the Arc or Beam) to create an immersive movie experience.
Alternatives
If you need a speaker you can take to the park or use by the pool, search for models with a built-in battery and an IP67 waterproof rating. If you're building a smart home around Google, look for speakers that specifically list 'Google Assistant' support, as this model does not have it.
