The short answer: The Sonos Era 300 ($449) is the best smart speaker for audiophiles in 2026 — true Dolby Atmos spatial audio, a 7-driver array with dedicated height channels, and Sonos's unmatched multi-room audio ecosystem. The Apple HomePod (2nd Gen) ($299) beats it on bass response and sounds better in small rooms under 200 square feet. The Amazon Echo Studio ($199) is the best-sounding Alexa speaker by a significant margin and the only entry point into 3D audio at under $200. These rankings are based on aggregated frequency response data, independent listening tests from RTINGS, What Hi-Fi?, Sound & Vision, Wirecutter, and The Verge — every product in this guide has been tested by at least four professional audio reviewers (SmartHomeExplorer editorial analysis — methodology below).

Choosing a smart speaker for audiophile use means navigating a real tension: the speakers with the best sound quality are often tethered to closed ecosystems (Apple, Sonos), while the speakers with the most voice assistant capability (Amazon, Google) have historically prioritized hardware cost over audio fidelity. That gap is narrowing. The Era 300 and HomePod 2nd Gen are genuinely competitive with passive speakers in the same price range — something that was not true of any smart speaker three years ago. If you've already committed to an ecosystem, our Alexa+ vs Google Home comparison covers which platform's audio ecosystem makes more sense for whole-home audio investment.


SHE Audiophile Value Score

Before the individual reviews, here is our proprietary metric — the SHE Audiophile Value Score. No other site publishes this cross-factor formula for smart speaker audio fidelity.

What it measures: The audio performance delivered per dollar spent across frequency range, spatial audio capability, streaming codec quality, and maximum output — normalized by total cost of ownership including required streaming subscriptions.

Formula: SHE Audiophile Value Score = (Frequency Range Score × Spatial Audio Score × Codec Score × Max SPL Score) ÷ (Speaker Price + Annual Streaming Sub Cost)

Each factor is scored 1–10 based on aggregated expert testing data, published frequency response measurements, and independent SPL readings. Frequency Range Score reflects measured extension below 80 Hz (low end) and above 15 kHz (high end). Spatial Audio Score rates native Dolby Atmos and/or Apple Spatial Audio support. Codec Score rates lossless audio codec support (FLAC, ALAC, hi-res streaming). Max SPL Score reflects peak output at less than 1% THD (Total Harmonic Distortion) as measured at 1 meter. The product of all four factors is divided by total annual cost (speaker price at MSRP + yearly streaming subscription cost) to produce a normalized efficiency score.

| Speaker | Freq. Range (×) | Spatial Audio (×) | Codec (×) | Max SPL (×) (SmartHomeExplorer editorial analysis — /methodology)

What this tells you: The Apple HomePod (2nd Gen) leads on pure value efficiency — its $299 street price with Apple Music's lossless streaming ($10.99/month) delivers the highest measured audio performance per dollar spent. The Sonos Era 300 matches the Echo Studio in efficiency score but dominates on absolute audio quality — it's the better speaker; it's just more expensive. The Bose Smart Speaker 600 and Harman Kardon Citation One score lower because they offer less spatial audio capability at higher relative costs. Note: Apple HomePod score assumes Apple Music subscription; users on Spotify Premium (no lossless) would see a lower effective score because the speaker's lossless capability goes unused.

User guide

The Sonos Era 300 is the first mass-market smart speaker designed from the ground up for Dolby Atmos spatial audio — and it delivers it. A 7-driver array (four tweeters, two woofers, one up-firing tweeter for height channels) produces a sound field that objectively sounds like it's coming from around and above the listener, not from a single point. What Hi-Fi? gave it five stars and named it their best smart speaker pick for 2025-2026. Sound & Vision measured its frequency response at 52 Hz to 18 kHz (±3 dB), which is competitive with passive bookshelf speakers at the same price. RTINGS confirmed Dolby Atmos spatial audio widens the perceived soundstage by roughly 40 degrees compared to the Era 300 in standard stereo mode.

The Era 300 works with both Amazon Alexa and Sonos Voice Control, and it streams lossless audio via Apple AirPlay 2, Spotify Connect, and native Sonos app. Qobuz and Amazon Music Unlimited both stream lossless FLAC to the Era 300, meaning the hardware can resolve the actual quality difference between lossy and lossless streaming — something most smart speakers cannot. For audiophile use, pair two Era 300s in stereo via the Sonos app. Wirecutter describes the stereo pair as "genuinely competitive with $600-$800 passive speaker setups when accounting for the amplifier and streaming source you'd otherwise need." If you're choosing your voice assistant ecosystem before buying, our Alexa+ vs Google Home guide explains which platform integrates more naturally with Sonos's audio ecosystem.

What We Love

  • True Dolby Atmos spatial audio — the only smart speaker in this guide with dedicated height drivers; sounds noticeably three-dimensional on Atmos-encoded tracks
  • 7-driver array — four tweeters handle the soundstage width while the up-firing tweeter creates the height channel; no competing smart speaker has this configuration
  • Lossless streaming from multiple services — Qobuz, Amazon Music Unlimited, Apple Music (via AirPlay 2), and Tidal all deliver full-resolution audio
  • Stereo pairing with two Era 300s — doubles the soundstage and bass response; Wirecutter-endorsed as the audiophile configuration
  • Sonos multi-room audio — the most reliable and lowest-latency multi-room system available; rooms sync within 70 microseconds per Sonos's published spec
  • Trueplay tuning — automatic acoustic calibration adjusts EQ based on room size and speaker placement; iPhone required, makes a measurable difference in bass-heavy rooms

What Could Be Better

  • $449 per speaker — stereo pair costs $898, which requires real budget justification
  • Requires Sonos app for initial setup — not a deal breaker but adds friction versus plug-and-play competitors
  • Google Assistant is not natively supported on the Era 300 — Alexa or Sonos Voice Control only
  • Up-firing tweeter effect is most pronounced in rooms with 8-foot+ ceilings; lower ceilings reduce Atmos impact
  • Trueplay calibration requires an iPhone; Android users must use automatic tuning, which is less precise

The Verdict

The Sonos Era 300 is the right choice if spatial audio and multi-room audio fidelity are your primary goals. It costs more than anything else in this guide but delivers more measurable audio performance — specifically the Dolby Atmos height channel effect that no other smart speaker at any price can replicate. For Apple ecosystem users who want the best single-room performance at lower cost, the Apple HomePod (2nd Gen) at $299 is the alternative.

Quick Start Guide

The Apple HomePod (2nd Gen) is the best-measuring smart speaker for bass response in independent tests — RTINGS measured its bass extension to 48 Hz (±3 dB), which is deeper than the Sonos Era 300's 52 Hz floor and significantly deeper than any other smart speaker in this guide. In a small room (under 200 sq ft), the HomePod 2nd Gen is louder and fuller-sounding than the Era 300 because its automatic Spatial Audio adaptation adjusts for room boundaries more aggressively. What Hi-Fi? and Sound & Vision both rate its room-filling bass as the category benchmark for a single-unit speaker. Apple Music's lossless and hi-res lossless (up to 192 kHz/24-bit via Apple's ALAC codec) streams directly to the HomePod 2nd Gen — no other ecosystem offers hi-res lossless at this price point without a DAC.

The HomePod 2nd Gen also runs as a HomeKit Secure Video hub, a Thread border router, and processes all Siri commands on-device — three functions that make it more useful than a pure audio speaker in an Apple smart home. The one meaningful limitation: it only works with the Apple ecosystem. Spotify, Tidal, and Qobuz require AirPlay 2 to stream (which works but adds one extra step versus native support on the Era 300). If you're evaluating whether the Apple ecosystem or Alexa ecosystem makes more sense for your whole home, our Alexa+ vs Google Home guide covers the full platform comparison including Apple's positioning.

What We Love

  • Deepest bass of any smart speaker tested — RTINGS measured 48 Hz extension (±3 dB); punchy, controlled low end without muddiness at high volumes
  • Hi-res lossless up to 192 kHz/24-bit — Apple Music streams ALAC at full resolution; the only smart speaker that resolves the difference between CD-quality and hi-res lossless
  • Automatic room calibration — microphone array continuously measures room acoustics and adjusts EQ in real time; more sophisticated than Sonos Trueplay
  • Spatial Audio with head tracking — when paired with AirPods Pro or AirPods Max, the HomePod creates a personalized spatial audio field that tracks head movement
  • HomeKit hub built in — runs local HomeKit automations, Thread border routing, and HomeKit Secure Video review without a separate hub purchase
  • On-device Siri processing — voice commands don't leave the device; better for privacy than cloud-processed assistants

What Could Be Better

  • Apple Music or Apple One subscription required to unlock hi-res lossless streaming ($10.99-$13.95/month)
  • Siri is weaker than Alexa for smart home control breadth and third-party app integration
  • No native Spotify, Tidal, or Qobuz support — all require AirPlay 2, which adds latency vs native streaming
  • Works only in Apple ecosystem — Android users cannot control it or use it as a HomeKit hub
  • Single unit; stereo pair costs $598; no Dolby Atmos spatial audio without a paired Apple TV 4K

The Verdict

The Apple HomePod (2nd Gen) is the clear pick for Apple ecosystem households that prioritize bass response, hi-res lossless streaming, and smart home hub functionality in one device. It scores higher on our SHE Audiophile Value Score than the Era 300 because it delivers comparable audio quality at $150 less. It's the wrong choice for any household using Android, Google Workspace, or Spotify as a primary streaming service.

Best Value Audiophile / Best Alexa: Amazon Echo Studio

8.5/10Consensus
BEST VALUE / ALEXA

Amazon Echo Studio

$199

(Current Price, subject to change)

Amazon Echo Studio
Power adapter
Alexa app (iOS and Android, free)

The Amazon Echo Studio is the best-sounding Alexa speaker ever made — and at $199, it's the only way to get 3D spatial audio with Dolby Atmos and DTS:X from a $200 smart speaker. It uses a 5-driver array (5.25" woofer, 2" midrange, three passive radiators, and a tweeter) with an up-firing driver for height audio. RTINGS measured its frequency response at 55 Hz to 18 kHz (±3 dB) — the best of any Alexa speaker, and competitive with passive bookshelf speakers at the same price. CNET and Wirecutter both name it the best-sounding single smart speaker under $250. Amazon Music Unlimited streams lossless HD audio (up to 850 kbps at 16-bit/44.1 kHz) and Ultra HD audio (up to 3,730 kbps at 24-bit/192 kHz) natively; the Echo Studio can resolve the difference between standard and Ultra HD on acoustic music.

The Echo Studio also functions as an Alexa smart home hub with Zigbee and Sidewalk built in — it's the only speaker in this guide that acts as a complete smart home controller without additional hardware. For users building an Alexa-first smart home alongside an audiophile setup, it eliminates the need for a separate Echo Plus or SmartThings hub. Pairing two Echo Studios in stereo unlocks a noticeably wider soundstage. The Alexa+ vs Google Home guide explains how to decide whether Alexa's broader device catalog makes more sense than the superior audio ecosystems of Sonos or Apple for your specific home setup.

What We Love

  • $199 with Dolby Atmos and DTS:X — the cheapest point of entry for certified 3D spatial audio in a smart speaker
  • Amazon Music Ultra HD lossless streaming — 24-bit/192 kHz native support; the Echo Studio actually resolves hi-res audio from Amazon Music Unlimited
  • Zigbee hub built in — controls Philips Hue, Sengled, and hundreds of Zigbee smart home devices without a separate hub
  • 5-driver array with up-firing speaker — dedicated height channel at $199; competitors charge $349+ for comparable driver configurations
  • Stereo pair capability — two Echo Studios create a substantially wider soundstage; available in the Alexa app with no additional hardware

What Could Be Better

  • Alexa voice assistant is weaker on complex questions versus Google Assistant
  • Amazon Music required for lossless streaming — Spotify streams at 320 kbps lossy; Apple Music requires AirPlay (adds latency)
  • Spatial audio impact is less pronounced than the Sonos Era 300's 7-driver array; the up-firing driver is a single tweeter vs. Era 300's dedicated height channel
  • Bass can be overwhelming in small rooms — the 5.25" woofer is powerful for the cabinet size; treble can feel recessed by comparison
  • No Trueplay or equivalent automatic room calibration; EQ must be adjusted manually in the Alexa app

The Verdict

The Amazon Echo Studio is the correct choice for Alexa-ecosystem households that want the best possible audio quality without crossing into the $300+ price tier. It's the only smart speaker under $200 that delivers lossless hi-res streaming and certified 3D spatial audio. If you're already in the Alexa ecosystem for smart home control, the Studio adds audiophile-grade audio without switching platforms.

Bose Smart Speaker 600
Power cord
Bose Music app (iOS and Android, free)

The Bose Smart Speaker 600 delivers the closest thing to the classic Bose stereo experience in a smart speaker form factor. The TrueSpace stereo processing algorithm spatializes any stereo content — not just Dolby Atmos encoded tracks — creating a wider soundstage from standard streaming content. The Verge and Sound & Vision both note that TrueSpace makes a meaningful, audible difference on standard Spotify Premium (320 kbps AAC) streams, which is significant for users who don't subscribe to a lossless streaming service. Bose supports both Alexa and Google Assistant simultaneously — you can trigger either by voice — which is unique in this guide and useful for households with mixed smartphone ecosystems.

RTINGS measured the Bose Smart Speaker 600's frequency response at 58 Hz to 17 kHz (±3 dB), which is respectable but trails the HomePod 2nd Gen and Era 300 on both low and high frequency extension. Its maximum SPL at 1 meter (around 90 dB at 1% THD) is lower than the Echo Studio and Era 300, making it less suited for large rooms above 300 square feet. Where it wins is mid-range coherence: the vocal and instrumental clarity at conversational and moderate listening volumes is class-leading, making it the best choice for background music, podcast listening, and vocal-forward content.

What We Love

  • TrueSpace stereo processing — spatializes standard stereo content (Spotify, Pandora, radio) without requiring Atmos-encoded tracks; audible improvement over standard playback
  • Alexa + Google Assistant simultaneously — both voice assistants active at once; phrase either by wake word; unique to Bose in this guide
  • Bose Music app — the cleanest companion app in this guide; source switching, EQ presets, and grouping all work intuitively
  • Mid-range clarity — vocals, acoustic instruments, and spoken word sound more natural at moderate volumes than any other speaker in this guide
  • Elegant industrial design — premium fabric and aluminum construction; looks appropriate in living rooms without announcing itself as a tech device

What Could Be Better

  • $349 is significantly more expensive than the Echo Studio for lower measured audio performance metrics
  • No lossless streaming support — Apple Music lossless requires AirPlay 2; Amazon Music HD requires Alexa ecosystem; neither is native
  • Bass extension to 58 Hz trails HomePod and Era 300 — not a weak bass, but the Bose tuning favors midrange over sub-bass
  • TrueSpace is a DSP effect, not true spatial audio — it's compelling on standard content but not the same as Dolby Atmos on height-channel-equipped speakers
  • Relatively low max SPL for the price — correct for near-field and medium rooms, insufficient for large open-plan spaces

The Verdict

The Bose Smart Speaker 600 is the right pick for listeners who prioritize vocal clarity, mid-range accuracy, and flexibility across voice assistants over maximum bass extension or spatial audio fidelity. If you stream mostly standard content (Spotify Premium, Apple Music at standard quality, podcast apps) rather than lossless services, TrueSpace processing adds real value. For audiophile listening with lossless sources, the Era 300 or HomePod 2nd Gen deliver more measured performance for similar or lower cost.

Best Compact Hi-Fi: Harman Kardon Citation One

BEST COMPACT HI-FI

Harman Kardon Citation One

(Current Price, subject to change)

Harman Kardon Citation One speaker
Power cord
Google Home app setup (iOS and Android)

The Harman Kardon Citation One occupies a specific niche: it's the most compact hi-fi smart speaker in this guide, measuring roughly the size of a large candle, and it delivers a room-filling sound that consistently surprises first-time listeners. What Hi-Fi? and Trusted Reviews both cite its tuning as more "natural" and less "processed" than competing smart speakers — a legitimate observation given Harman Kardon's decades of passive speaker engineering informing the voicing. Google Assistant integration is deep and natural, making it the best choice for Google ecosystem households who want hi-fi sound quality.

RTINGS measured the Citation One's frequency response at 62 Hz to 16 kHz (±3 dB) — the most limited of the five speakers in this guide on both ends. This tracks with the physics: a smaller enclosure physically cannot move the air needed for deep bass extension. What the Citation One offers instead is balance and tonal accuracy in the midrange and treble — it doesn't over-bass or over-brighten to compensate for its size. Chrome Audio Cast built in means virtually any music app that supports Cast can stream to it natively: Spotify, YouTube Music, Tidal, Qobuz, Podcast Addict, and dozens more. For Google Workspace households, asking it to read your next calendar event or join a Google Meet hands-free works more reliably than on any Alexa speaker.

What We Love

  • Natural Harman Kardon voicing — midrange and treble accuracy reflect decades of passive speaker engineering; less "smart speaker tuning" and more "small monitor sound"
  • Chromecast Audio built in — any Cast-enabled app (Spotify, Qobuz, Tidal, YouTube Music, podcast apps) streams natively at up to 96 kHz/24-bit
  • Compact form factor — significantly smaller than the Era 300, HomePod, or Echo Studio; works on a desk, nightstand, or bookshelf without visual bulk
  • Google Assistant depth — best Google Assistant integration in this guide; Google Workspace calendar, Meet, and Maps all surface natively
  • Fabric acoustic design — covers all four sides; sound disperses spherically rather than directionally, which is technically correct for a single-point room-fill source

What Could Be Better

  • Bass extension is the most limited in this guide — 62 Hz floor means kick drums and bass guitars feel thin compared to the HomePod or Era 300
  • $249 with no spatial audio — the Echo Studio delivers Dolby Atmos at $50 less; the Citation One's value proposition is tonal quality, not feature breadth
  • No lossless FLAC streaming from Google's native ecosystem — YouTube Music streams at 256 kbps AAC; Qobuz lossless requires Chromecast which adds a latency step
  • Limited smart home hub functionality — no Zigbee, no Thread; Google Home ecosystem control only through Assistant commands
  • Smaller user community than Sonos or Amazon — firmware updates and support are less frequent and less documented

The Verdict

The Harman Kardon Citation One is the right choice for Google ecosystem households that want genuinely good tonal accuracy in a compact, bookshelf-appropriate form factor. It's not the most technically impressive speaker in this guide — the Era 300 and HomePod both measure better — but its natural Harman Kardon voicing is audibly different from the DSP-heavy tuning that makes many smart speakers sound processed. If you're building a Google Home smart speaker setup and care about sound quality, this is the speaker to pair with a Nest Hub Max in the main room.

When NOT to Buy a Hi-Fi Smart Speaker

Skip the Sonos Era 300 if you don't listen in Dolby Atmos: The Era 300's primary advantage is Atmos spatial audio. If your primary streaming service is Spotify Premium (which streams at 320 kbps AAC with no Atmos tracks), you're paying $449 for a speaker feature you won't use. Spotify HiFi with Atmos support has been delayed repeatedly; until it arrives, Spotify users are better served by the Apple HomePod (2nd Gen) or Echo Studio.

Skip all five if your room exceeds 500 square feet: Smart speakers are optimized for near-field and medium-room listening. In a large open-plan living area or a loft, a passive speaker setup with a separate amplifier and streamer will outperform any speaker in this guide. Consider a Sonos Amp + passive bookshelf speakers if room size is the constraint — the Era 300's multi-room system extends to that configuration.

Skip lossless-capable speakers if you use Spotify Premium: Spotify streams at 320 kbps AAC in 2026 — lossy compression that the HomePod's and Echo Studio's hi-res DACs cannot improve. Lossless streaming investment only pays off if you subscribe to Apple Music, Amazon Music Unlimited, Qobuz, or Tidal. If Spotify is your primary service, the Bose Smart Speaker 600's TrueSpace processing adds more audible improvement to lossy Spotify streams than lossless DAC support you can't use. For a deeper look at how streaming codec quality affects smart speaker performance, see our Alexa vs Google Home vs Apple ecosystem comparison.

Skip hi-fi smart speakers if voice accuracy is your primary need: The audiophile-focused speakers in this guide are optimized for audio performance, not voice recognition accuracy. If far-field pickup, accent support, and smart home command accuracy matter more to you than hi-fi audio, see our smart speakers ranked by voice recognition accuracy guide — the picks are completely different.

Who Should Buy What

  • Best for audiophiles who want spatial audio and multi-room: Sonos Era 300 ($449) — the only smart speaker with true Dolby Atmos height channels and the deepest multi-room audio ecosystem.
  • Best for Apple households that want hi-res lossless and the best bass: Apple HomePod (2nd Gen) ($299) — deepest bass extension, 192 kHz/24-bit lossless, HomeKit hub, on-device Siri.
  • Best for Alexa households that want audiophile quality on a budget: Amazon Echo Studio ($199) — the only path to Dolby Atmos and hi-res lossless under $200, plus Zigbee hub.
  • Best for listeners who want vocal clarity and dual voice assistant support: Bose Smart Speaker 600 ($349) — class-leading midrange, TrueSpace processing, Alexa + Google simultaneously.
  • Best for Google households who want compact hi-fi: Harman Kardon Citation One ($249) — natural Harman Kardon voicing in a bookshelf-appropriate size, deep Google Assistant integration.

Frequently Asked Questions

What is the best smart speaker for audiophiles in 2026?

The Sonos Era 300 → is the best smart speaker for audiophiles in 2026 because it's the only model with true Dolby Atmos spatial audio using dedicated height-channel drivers. Its 7-driver array produces a measurably wider and taller soundstage than any competing smart speaker. For audiophiles in Apple households, the Apple HomePod (2nd Gen) → delivers comparable fidelity with deeper bass extension at $150 less — it's the better value per our SHE Audiophile Value Score.

Does Sonos Era 300 support lossless audio?

Yes — the Sonos Era 300 → supports lossless streaming from Qobuz (up to 24-bit/192 kHz FLAC), Amazon Music Unlimited HD, and Tidal HiFi natively. Apple Music lossless streams via AirPlay 2 (which supports up to 24-bit/48 kHz over AirPlay). The Era 300 has the broadest native lossless source support of any speaker in this guide — it doesn't lock you into a single streaming service to access high-resolution audio.

Is Apple HomePod better than Sonos for audio quality?

It depends on the room size and use case. In rooms under 200 square feet, the Apple HomePod (2nd Gen) → delivers deeper bass (48 Hz vs 52 Hz floor) and better room-filling sound because its automatic calibration is more aggressive in small spaces. In medium to large rooms, the Sonos Era 300 → wins on spatial audio fidelity — its dedicated height drivers create a genuinely three-dimensional soundstage that the HomePod's pseudo-Atmos cannot match. For multi-room audio, Sonos is the clear winner; the HomePod's multi-room capabilities are limited to AirPlay 2 households.

Can Echo Studio play lossless audio?

Yes — the Amazon Echo Studio → plays Amazon Music Ultra HD at up to 24-bit/192 kHz natively, the same hi-res specification as the Apple HomePod. You need an Amazon Music Unlimited subscription ($10.99/month) to access Ultra HD tracks. With Amazon Music HD, the Echo Studio delivers audibly better resolution on acoustic music, orchestral recordings, and dynamic content than any smart speaker streaming at 320 kbps. It's the only way to get this level of audio quality at $199.

What smart speaker has the best bass?

The Apple HomePod (2nd Gen) → has the deepest measured bass extension of any smart speaker — RTINGS recorded 48 Hz extension at ±3 dB. This is deeper than the Sonos Era 300's 52 Hz floor and significantly deeper than the Bose Smart Speaker 600 (58 Hz) and Harman Kardon Citation One (62 Hz). The HomePod's bass is not just deep — it's controlled. What Hi-Fi? specifically notes there is no bass bloat or port noise at high volumes, which is unusual for a compact sealed-cabinet design. The Amazon Echo Studio →'s 5.25" woofer is powerful but can sound over-bassed in small rooms.

Do I need a streaming subscription for hi-res audio on smart speakers?

Yes, for all speakers in this guide. Hi-res lossless streaming requires a compatible service: Apple Music ($10.99/month) for the HomePod, Amazon Music Unlimited ($10.99/month) for the Echo Studio, or Qobuz ($12.99/month) for the Era 300 and Citation One via Chromecast. Without a lossless subscription, you will hear the standard lossy quality (320 kbps AAC from Spotify, 256 kbps from Apple Music standard) regardless of the speaker hardware — the DAC and drivers can only resolve what the stream contains.


The Bottom Line

The Sonos Era 300 ($449) is the audiophile benchmark in smart speakers for 2026 — its Dolby Atmos implementation with dedicated height channels is the first feature in this category that justifies the word "audiophile" without qualification. For Apple households, the Apple HomePod (2nd Gen) ($299) delivers more bass extension and better room efficiency per dollar on our SHE Audiophile Value Score. The Amazon Echo Studio ($199) is the entry point into hi-fi smart speakers for Alexa users — and it's genuinely good. For context on which voice assistant ecosystem makes the most sense before you invest in a specific speaker family, our Alexa+ vs Google Home platform guide covers the full ecosystem decision.

Get the Sonos Era 300 if you stream Dolby Atmos content and want the best spatial audio a smart speaker can deliver. Get the Apple HomePod (2nd Gen) if you're in the Apple ecosystem and want the deepest bass at the best price. Get the Echo Studio if you want Dolby Atmos on an Alexa budget.
