Sonos Era 100 SL: two-minute review
The Sonos Era 100 SL is a wireless speaker that features nearly all the strengths of 2023’s original Sonos Era 100, but at a cheaper price. While it isn’t a surprise that there have been some trade-offs to get that cost down, I doubt they’ll be a dealbreaker for most people.
Sonically speaking, there aren’t many sacrifices at all. In the mid-range, the Era 100 SL is capable of impressive detail. When I played I Want You by Moloko, I was impressed by how well its funky guitar noises, strings and acidy synth line cut through the mix, without interfering with the wonderfully polished vocals.
However, I found the high end a little more cluttered on occasion: listening to The Gloaming by Radiohead, I did feel that the rhythmic pulsing static was a bit too forward, treading on the toes of the granular synth. It sounds great for the price, but you do get a finer presentation if you pay more.
Bass was always the original Era 100’s achilles heel. It often tipped into being brash, slightly swamping the rest of the mix. When I played Six Days (Machinedrum remix) by DJ Shadow on the SL, the low-end appeared slightly more dynamic when compared to the original Era 100, leading me to wonder if a software tweak to rein in bass was responsible, or whether it’s part of the re-engineering inside that Sonos CEO Tom Conrad told us the company had done, to hit the lower price.
Either way, it still isn’t great with sub, though: it falls away just when it hits the drop, that swelling bassline feeling nowhere near as substantial as it sounds on the best wireless speakers that are pricier.
Generally, though, the SL offers a spacious presentation, especially when fed high-quality recordings. Playing Wasting My Young Years by London Grammar from Tidal’s hi-res tier, I was struck by the airiness of the mix, which allowed the silvery vocals to stand apart from the piano and drums.
Unfortunately, this doesn’t quite extend to the speaker’s stereo field — as with its predecessor, I found it hard to differentiate a clear stereo separation unless I was very close. As such, you’re unlikely to get a clear sense of left and right from halfway across the room — but then, at this price, you could actually buy two happily.
So the Era 100 SL is as easy on the ear as its predecessor, albeit with some of the same drawbacks. But how does it look?
Given it’s largely decked out in the same getup as the Era 100, there really are few surprises here. It’s the same dimensions and has the same wraparound grille and matte-plastic top surface. The touch-capacitive control scheme is also largely identical — with the voice control button being the only real omission, because Sonos removed that feature. Otherwise, Sonos has stuck with what works for the SL, and I’d say that was the right instinct.
In fact, probably the only area where the SL makes a real departure from its namesake is in its feature set. Connectivity remains solid, offering Wi-Fi 6, AirPlay 2 and a whole host of built-in streaming services — although the only wired input you’ll get is if you splash extra cash on its USB-C to 3.5mm analog converter. EQ options are identical to those on the Era 100, offering just the option to boost or duck bass or treble.
But there are two significant differences. First off, as I alluded to above, voice control has been stripped out of the SL. This feels like a reasonable sacrifice to lower that price — and I’d rather that than weaker sound quality.
Slightly more an issue for me is the omission of Trueplay room correction for Android users (which is a consequence of dropping the microphones, since the Android solution relies on them). Those with an iPhone can still tailor the SL’s sound to their space using their device to track calibration sound as they walk around the room. Given how well this feature polishes its sound, it is a shame that you’ll miss out if you’re on an Android device.
Despite this though, the Sonos Era 100 SL is well worth it. You get the quality sound plus classic design of Sonos’s pricier speaker, for the reduced price of $189 / £169 / AU$289. That’s a pretty great bargain and ameliorates our biggest hesitation with its pricier predecessor. Yes, it’s a shame that Android users miss out on a great feature but it’s still the best home speaker you’ll get for this price.

Sonos Era 100 SL review: price & availability
- Launched on March 31, 2026
- Costs $189 / £169 / AU$289
- Available in black or white
Having launched on March 31, 2026, the Sonos Era 100 SL is available now, at a cheaper price than its predecessor, the Era 100.
The SL comes in at $189 / £169 / AU$289, compared to the Era 100’s now-reduced price of $219 / £199 / AU$319. While not a huge gulf, it still amounts to a decent saving, especially given the near-identical specs.
And, as is usually the case with Sonos gear, for that price you have the option to pick up the speaker in white or black.
Sonos Era 100 SL review: features
- Good connectivity options and streaming service support
- Room correction only compatible with iPhone
- No voice control of any kind
So how does the Sonos Era 100 SL’s featureset differ from its spendier stablemate? Well, on paper, it’s very similar to the Era 100, with only a couple of key differences.
Let’s start with its drivers. The SL offers the same setup as as the Era 100, with a mid-woofer to handle both mid-range frequencies and bass, while two angled tweeters take care of the treble and help form its stereo field. These are all driven by the speaker’s three class D amplifiers, meaning you get decent volume and low-end heft.
Setting up Sonos products has always been a breeze, and the Era 100 SL is no exception. Simply plug it in, download the Sonos app, and select the system you want to add it to. Tap on your speaker when it appears, and it will play an audio pin to connect it to your system. After installing an update via the app, I was good to go.
The last (optional) step is to set up the SL’s Trueplay room-calibration tuning, which is designed to get you the best possible sound from the speaker, and that works much the same as it did on the Era 100.
Essentially, you point your iPhone’s mic toward the speaker, then walk around the room while whirling it around in slow circles with one arm, like a lopsided propeller.
Following calibration, the sound definitely seemed free of obvious acoustic issues — there wasn’t any boom back from the bass, nor any unfortunate reverberations off the surfaces or walls — so Sonos’ room correction seems as effective as ever.
Unfortunately, there’s a pretty major caveat here: unlike on the Era 100, the SL’s Trueplay tuning is only compatible with iOS. And that is a real shame, given it does help unlock the SL’s best sound. However, it still offers great performance for Android users, even if the lack of Trueplay does add an asterisk there.
Trueplay for Android users isn’t the only feature removed to help reduce the SL’s price. The voice control offered by the full Era 100 has been omitted, too, saving you the price of the mic module and controls. Personally, it takes me far longer to horsewhip my thoughts into a spoken command than it does to simply pull out my phone, so I’m not all that bothered about the lack of voice assistant. But if you are, you’ll probably prefer the Era 100.
While I’ve mentioned how much I rate the Era 100 SL’s room-correction tech, I can’t really say the same for its EQ options. The Sonos app only offers the ability to boost or duck the treble or bass by up to 10 levels. While I do think Sonos’s speakers sound a lot better than some wireless speakers out of the box, plenty of rivals now offer nine-band or even parametric EQ — which makes the SL’s bass and treble sliders feel like old hat.
As far as connectivity options are concerned, the Era 100 SL offers a decent range. Using Wi-Fi 6, you can stream tunes directly from your devices using AirPlay 2, or from the speaker using built-in apps including Amazon Music, Apple Music, Deezer, Soundcloud, Spotify, Tidal and a whole heap more. Meanwhile, Bluetooth 5.3 will allow you to hook up all your non-Apple devices, although there’s no support for higher-res formats such as aptX HD.
Sadly, the Era 100 SL is less well equipped when it comes to physical connections. Its USB-C port is only for plugging in adapters, so banish any thoughts of hooking up wired digital audio. So while it does allow you the option for plugging in either a 3.5mm jack for analog audio or an Ethernet cable, each of these requires you to buy a separate adapter. It’s a world away from the wealth of ports that a speaker such as the Bluesound Pulse Flex offers.
Sonos Era 100 SL review: sound quality
- Impressive detail
- Rich mids, and bass feels slightly less muddy
- Relatively weak stereo field
My big worry when preparing to test the Sonos Era 100 SL was that in trying to hit the cheaper price point, there would have been a negative impact on the quality of its sound. Fortunately, I’m pleased to reveal this isn’t the case — the Era 100 SL happily holds its own against its predecessor and, in some areas, I actually wonder if software tweaks have reined in some of the Era 100’s worst impulses.
First, let’s start with the mid-range. When listening to Venera by George Fitzgerald, I was impressed with how much presence and detail the SL could squeeze out of the track’s vocal, pad washes and synth lines, making them sound like a richly textured whole. Admittedly, some of the percussion felt a little less punchy than I’m used to, but that was more than made up for by how well it balanced the saturated, arpeggiated synth and organic organic woodwind sounds that close out the track.
The original Era 100 came unstuck mainly in the bass — like an overexcitable puppy, it was both enthusiastic and yet lacking in discipline. Here, it sounds like the SL’s software has been tweaked slightly to rein this in.
Comparing Listen by Pola & Bryson and Goddard on both speakers, sustained bass notes sound less reverberant and flabby on the SL, while snarling distorted bass synths seem more tightly expressed. However, not that if you’re expecting super-low bass from either device, you’ll be left wanting: there’s very little in the way of sub from either.
I tested the SL’s treble by playing Go Your Own Way by Fleetwood Mac — an exam it easily passed, even if it didn’t quite ace it. There wasn’t any unpleasant distortion or oversaturation to it, while the snare and toms had a delicious punch that kept everything moving forward. However, my one reservation was that the rhythmic punch and the polished vocals slightly outshone the twangy rhythm guitar — for me, they’re part of what makes the track so iconic, so it was a shame they didn’t get to share as much of the limelight.
Given the Era 100 SL doesn’t exactly sit at the premium end of the market, it also does a good job of separating different instruments in the mix. Playing a hi-res stream of Clair de Lune by Kamasi Washington straight from Tidal, I was impressed by the clarity of timbre of each instrument, especially during the solos. The trumpet beautifully conveys the instrument’s rich harmonics, while the sliding strings of the double bass as the player launches into their solo are brilliantly expressed.
Like its predecessor, the SL is only capable of so-so stereo. Unlike some more premium speakers, it still largely feels like the sound is issuing from a single point. And when I played Manchild by Eels, I could appreciate the stereo separation between elements — with the guitars clearly panned to the right and the vocals to the left — but only when I was sat within a few feet of the device. At least listening angles are pretty consistent, with only a very slight drop off in the treble as you travel toward the speaker’s back.
All in all, my biggest worries going into this were ill-founded. Despite the cheaper price of the Sonos Era 100 SL, it doesn’t demonstrate any significant sonic sacrifices compared to its full-fat sibling. And there may have even been a few software tweaks behind the scenes to slightly rein in the wilder tendencies of the older speaker. Either way, it’s a very decent-sounding speaker for the price.
- Sound quality score: 4.5 / 5
Sonos Era 100 SL review: design
- Almost identical to the Era 100
- Solid, tactile build
- Effective touch-capacitive controls
When it comes to looks, the Sonos Era 100 SL remains almost identical to its older sibling. They share the same cylindrical ellipse shape, are wrapped in the same metallic grille, and arrive in the same black or white colorway. If you’ve ever gawked at the older Era 100, you’ll know exactly what you’re getting here.
All in all, the Era 100 SL is decently stylish, feels solidly built, and the matte plastic of its top surface is pleasingly tactile. While I’ve poured scorn on quite a few wireless speakers lately for defaulting to this same basic format, I’ll give Sonos a pass here. First off, it was largely the brand that coined this look in the first place — and, more importantly, the Era 100 SL is principally a cheaper speaker wearing its spendier brother’s clothing, meaning it was never going to break the mould of existing speakers.
In light of this, so not surprisingly, the Sonos Era 100 SL is the same size as its full-fat sibling, measuring 7.19 x 4.72 x 5.14 inches / 182.5 x 120 x 130.5mm. However, it’s ever so slightly lighter — presumably thanks to its shedding of voice control mics — weighing in at 4.3lbs / 1.95kg compared to its predecessor’s 4.45lbs / 2.02kg. That makes it a pretty average size in the grand scheme of things, neither Lilliputian like the 0.96lbs / 0.44kg Sonos Roam 2, nor Brobdingnagian like the hulking, 3 lbs / 14.5kg Cambridge Audio Evo One.
With one notable exception, the erstwhile voice control button, the buttons on the Era 100 SL are the same. And that’s very much a plus: there’s no need to fix the Era 100’s control scheme since it definitely isn’t broke. Its touch-capacitive controls are easy to activate, allowing you to play, pause and skip tracks, while swiping its touch bar lets you tweak its volume. Sure, it could offer light-up symbols for use in darker rooms or customizable shortcut keys, but it covers the core functions well.
Fundamentally, the Era 100 SL is the spitting image of the Era 100 before it. So if you were a fan of the older model, you can be sure you’ll like its younger sibling.
Sonos Era 100 SL review: value
In our review, one of our criticisms of the original Sonos Era 100 was its increased cost. Its initial list price of $249 / £249 / AU$399 presented a chunky markup on the Sonos One at $219 / £199 / AU$319 , but even more so when compared to the Sonos One SL’s $199 / £179 / AU$289. Even though the Era 100 has now come down in price to $219 / £199 / AU$319, that’s still only roughly comparable to the Sonos One.
Conversely, the Era 100 SL has a list price of $189 / £169 / AU$289, making it the same price or even cheaper than the Sonos One SL but with many of the same features and the exact same sound quality as the Era 100. That’s not to be sneered at.
In fact, if you’re an iPhone user, the only real thing you’re losing here is voice control, something I’m personally happy to sacrifice for a bit of a bargain. And even if you’re an Android user, this price is still well worth it as you’re unlikely to get much better performance by investing your spend elsewhere. Access to Trueplay is a definite bonus but that shouldn’t detract from the fact the SL still offers great sound for its price.

How I tested the Sonos Era 100 SL
- Tested it over four weeks
- Compared it to the Era 100 using a wide range of tracks
- Have decades of experience using audio hardware
I tested the Sonos Era 100 SL over the course of about a month. I made sure to utilize many of its key features, including room-tuning and EQ, and tried connecting to it through a range of options from direct streaming on the device through to connecting discrete devices using AirPlay 2.
To assess its sound quality, I played a wide variety of music, from classic rock to liquid drum & bass. I also compared the sound, side by side, with the Era 100 to see whether I could perceive any significant differences between their sound signatures. In addition, I compared each version’s stereo field and angle drop-off to see whether either revealed any issues with their soundstage.
As well as spending at least the past six years reviewing wireless speakers for tech publications, I have decades of experience using audio hardware in my home environment, including a range of wired and wireless speakers and headphones. I’ve also spent 20 years producing music from home, which has given me a firm understanding of how to assess the balance of frequencies and stereo elements.
