Sonos Era 100 Wireless Bluetooth Smart Speaker - S39 (PB1030932)
Used
Why we picked it #1
You'll get one of the most affordable Sonos Era 100 speakers here, making this a clear value pick if your main goal is saving cash without missing out on core features. Even though it's used, it's in very good cosmetic condition, meaning you won't have to worry about excessive wear. The power cable is included, so you're ready to set up immediately. While it doesn't come in the original packaging and only partial accessories are included, that's almost always a fair trade-off at this price point. Compared to the certified refurbished options, you're saving about $30, but giving up the peace of mind that comes with like-new condition and more complete accessories. Versus open-box listings, this option stands out for keeping costs down while still being in solid shape. If you're looking to get the Era 100 experience without overspending—and you don't mind minor signs of previous use—this is a great place to start.
Sonos Era 100 S39 Wireless WiFi & Bluetooth Smart Speaker Black
Used
Why we picked it #2
This listing is a step up if cosmetic condition tops your priority list. You'll get an Era 100 in excellent shape with the peace of mind that comes from knowing it's been well cared for. The power cable is included, so setup will be no hassle. Where you're paying a little bit more than the absolute cheapest options here, you get closer to 'like new' looks for that extra $15–$20. The seller has a track record for reliability, which helps offset the minor drawbacks: the original packaging isn't included, and the box itself is damaged (not ideal if you're gifting or looking for that unboxing thrill). One thing to double-check is the plug type—this one comes with a Type D plug, which might require an adapter depending on your region. Overall, this is a strong middle ground: not the bargain-basement price of the top pick, but better cosmetic condition and trustworthy seller history for a reasonable premium.
Sonos Era100 Black Certified Refurbished - Smart Speaker - Bluetooth - AirPlay2
Certified - Refurbished
Why we picked it #3
This certified refurbished listing is the closest you’ll get to a 'like new' Sonos Era 100 without paying retail. You’re getting an excellent condition unit with the full suite of original accessories—including the power cable—plus the original packaging, which can be reassuring for shipping safety and resale. The real bonus is the included Sonos Line-In Adapter, which lets you connect wired sources—a handy extra you’d otherwise have to buy separately. Because it's certified refurbished, you’re backed by warranty-equivalent protection, making it a lower-risk way to get premium hardware. You’re paying more than the used picks, but what you gain is peace of mind: great looks, all the accessories, and warranty support. If you want the confidence of 'basically new' and plan to use wired sources, this is worth the extra outlay versus straight used options.
Sonos Era100 White Certified Refurbished - Smart Speaker - Bluetooth - AirPlay2
Certified - Refurbished
Why we picked it #4
You get a Sonos Era 100 that’s certified refurbished, so condition and reliability are close to what you'd expect from a brand-new unit. All original accessories and the power cable come with it, plus the speaker arrives in the original packaging—perfect if you want the full unboxing experience or plan to gift it. You also benefit from warranty-equivalent protection that covers you against surprises. While you do pay a premium over used or even open-box options, you're really trading up for peace of mind and an essentially 'like new' experience. Unless saving every last dollar is your ultimate goal, this is a safe, hassle-free way to experience the Era 100, especially if you're concerned about reliability or are gifting. Unless you find the included line-in adapter of the black version (#3) essential, the only real deciding factor between these two refurbished picks will be color preference.
MINT Sonos Speaker ERA 100 Black With Box, Charger and Manual
Open box
Why we picked it #5
This is a mint, open-box Era 100—so you’re getting a speaker that’s been barely used and even retains the original box and manual, making it feel much closer to new. If you value condition, this is a standout: you get excellent looks, original packaging, and what’s most likely a complete accessory set. The small catch is the missing power cable, which you’ll need to supply yourself (an inexpensive fix, but something to factor in). There's also a minor downside if you’re outside the continental US: shipping is restricted. Against the cheaper used options, you’re paying a premium for condition and presentation, but that’s often worthwhile if you want to avoid the unknowns of heavier use. Compared to certified refurbished choices, this saves you a little money while giving you a speaker that’s barely been used—but you do sacrifice the official warranty safety net. If you care most about visuals and that nearly-new feeling, this is a smart bet.

Sonos Era 100
Sonos Era 100: Why Buy Used?
The Sonos Era 100 (released March 2023) is the direct successor to the Sonos One — and the new baseline for Sonos's compact smart speaker lineup. The Era 100 is a genuine generational upgrade: stereo sound from a single speaker (two angled tweeters + a 25% larger mid-woofer than Sonos One), Bluetooth 5.0 (a Sonos first for a wired smart speaker), USB-C line-in, AirPlay 2, Spotify Connect, and Trueplay tuning that finally works on both iOS and Android. At ~2-3 years old, used Era 100 prices are excellent for a speaker that defines the modern Sonos baseline.
What's New in Era 100 vs Sonos One
- True stereo from one speaker — Two angled tweeters + larger mid-woofer, with Sonos's beamforming for stereo separation.
- Bluetooth 5.0 — A Sonos first for a wired smart speaker. Use it standalone on a desk or kitchen counter without Wi-Fi.
- USB-C line-in — Connect a turntable, CD player, or any wired source via the Sonos USB-C-to-3.5mm Line-In Adapter (~$20, sold separately).
- Trueplay on Android — The Era line is the first Sonos hardware to support Trueplay tuning on Android phones (previous Sonos hardware required iOS for Trueplay).
- Wi-Fi 6 — Faster, more reliable wireless on modern routers.
- Hardware mic-mute switch + privacy LED — Physical privacy controls.
- Touch-and-swipe top controls — Replaces older capacitive-tap controls.
- No Google Assistant — Sonos One supported it; Era 100 does NOT. Choose Alexa or Sonos Voice Control instead.
Critical Used-Buyer Checks
The Sonos used market has account-binding nuances. Always verify before completing the purchase:
- The unit can be Factory Reset and re-registered to a new Sonos account. Ask the seller to reset before shipping, or do it yourself on receipt. If the device is still bound to the seller's account and they refuse to release it, S2 setup will fail until the previous registration is cleared.
- The OEM USB-C power adapter is included. This is the most-cited missing accessory on used Era 100 listings. Sonos's USB-C adapter delivers a specific power profile; third-party USB-C adapters may not deliver enough power for full output. Replacement OEM adapter is ~$25 from Sonos.
- All five microphones respond to the wake word with your chosen voice assistant.
- Bluetooth pairing works with at least one device.
- Touch controls are responsive across the full top surface — capacitive controls can develop dead zones with heavy use.
Era 100 vs Sonos One: Should You Pay More for Era 100 Used?
The Sonos One is still excellent and is now available very cheaply on the used market — but it's discontinued and Sonos has stopped selling it new. The Era 100 is the future of the lineup. The buying decision:
- Choose Era 100 if: you want Bluetooth, you want Android Trueplay, you want USB-C line-in capability, you have an Apple-only household, you want longer-term software support.
- Choose Sonos One (used) if: you want the lowest cost, you specifically want Google Assistant (Era 100 doesn't support it), or you want to add to an existing Sonos One stereo pair (mixing One and Era 100 in a stereo pair is NOT supported).
Era 100 vs Era 300: When to Step Up
The Era 300 is the bigger sibling — six drivers, true Dolby Atmos for music, larger physical footprint, ~2x the price. For most rooms (kitchens, bedrooms, home offices, small living rooms), the Era 100 is the right pick. Step up to Era 300 for: larger rooms, dedicated Dolby Atmos music listening (Apple Music spatial audio, Amazon Music), or use as Dolby Atmos rear surrounds with a Sonos Arc soundbar.
Stereo Pair, Home Theater Surround, Multi-Room
Two Era 100 units can be paired as a true stereo pair (left + right), with one acting as left channel and the other as right. They can also serve as rear surround speakers when paired with a Sonos Arc or Beam (Gen 2) soundbar — completing a 5.1 home theater setup. And of course they support full Sonos multi-room: group with any Sonos speaker via the S2 app.
Available Colors
Sonos Era 100 launched in Black and White. All colors share identical hardware — the choice is purely aesthetic.
Frequently Asked Questions
Will Sonos Era 100 work with my existing Sonos One stereo pair?
No — Era 100 and Sonos One cannot be stereo-paired together. Sonos requires both units in a stereo pair to be the same model (two Era 100s, two Sonos Ones, etc.). They CAN exist in the same household and be grouped for multi-room playback, but you cannot use one Era 100 + one Sonos One as a true left + right stereo pair. If you want a stereo pair upgrade path, plan to replace both Sonos One units with two Era 100 units, or keep the existing Sonos One pair separate and add the Era 100 as a single new room.
What accessories should be included with a used Sonos Era 100?
The original retail box includes: the Era 100 speaker, an OEM USB-C wall power adapter, and a printed quick-start guide. Only the OEM USB-C power adapter is essential. Sonos officially recommends only the OEM unit — third-party USB-C adapters may not deliver the specific power profile required for full output. Replacement OEM adapter is ~$25 from Sonos. The 3.5mm Line-In Adapter and the combo Line-In + Ethernet Adapter are sold separately (not in the original box) — they're optional accessories for using a turntable, CD player, or wired Ethernet.
What size room is Sonos Era 100 right for?
Sonos Era 100 is designed for small-to-medium rooms — bedrooms, home offices, kitchens, bathrooms, small living rooms, and dorm rooms. It's a notable upgrade over the Sonos One for larger small rooms thanks to the 25% larger mid-woofer. For larger rooms (~300+ sq ft) or for music-first listening, step up to Era 300 or pair two Era 100s as a stereo pair (which doubles output and provides true left + right separation). For very small rooms, a single Era 100 is more than sufficient — and a stereo pair is overkill.
How is Era 100 different from Sonos One? Should I bother upgrading?
Era 100 adds Bluetooth 5.0, USB-C line-in, Trueplay tuning on Android, Wi-Fi 6, hardware mic-mute, and a 25% larger mid-woofer. It removes Google Assistant support (Sonos One had it). For most users, the Bluetooth and USB-C line-in are the most-felt upgrades — they make the Era 100 a much more flexible standalone speaker. If you specifically rely on Google Assistant, the Sonos One is your last Sonos option; the Era line only supports Alexa and Sonos Voice Control. If you're starting fresh, Era 100 is the better long-term pick. If you have existing Sonos One units, upgrading just for hardware improvements is hard to justify unless you specifically want Bluetooth or Android Trueplay.
What apps does Sonos Era 100 work with?
The Sonos S2 app is required for setup, voice service configuration, and multi-room control. Once set up, Era 100 works with: AirPlay 2 (any Apple device — iPhone, iPad, Mac), Spotify Connect (Spotify app on any platform), Bluetooth (any phone, tablet, or laptop with Bluetooth 5.0 or earlier), and 100+ music services via the Sonos app (Apple Music, Amazon Music, Tidal, Pandora, Deezer, etc.). Notably, the Sonos S1 app is NOT supported on Era 100 — if your existing Sonos household is still on S1 (older Play:1, Play:3, ZonePlayer hardware), you cannot mix Era 100 in the same S1 household.
