Sony's most intelligent everyday earbuds.
The Sony LinkBuds S occupy a unique position in the earbud market — sitting between Sony's budget earbuds and the flagship WF-1000XM5, they inherit the best of Sony's audio technology at a price most people can justify. After two months of daily testing alongside the Apple AirPods Pro 2, Samsung Galaxy Buds2 Pro, and Bose QuietComfort Earbuds II, our editors recommend the LinkBuds S as the best all-day earbuds for commuters, office workers, and active users who want serious noise cancellation without the bulk or price of flagship earbuds. At 4.8g per earbud — lighter than a 5-yen coin — they are the most comfortable noise-cancelling earbuds available for extended wear.
What makes the LinkBuds S stand out is Adaptive Sound Control: an AI system that detects your activity in real time and adjusts the balance between noise cancellation and ambient sound automatically. On the train, it ramps up ANC. Walking into a convenience store, it fades in ambient sound. Sitting at your desk, it tunes to a soft transparency mode. You can spend an entire day wearing LinkBuds S without once touching them to change modes — the earbuds learn and adapt. Combined with DSEE Extreme AI upscaling that restores compressed streaming audio detail in real time, and 360 Reality Audio spatial sound support for compatible services, the LinkBuds S delivers a genuinely premium listening experience.
Adaptive Sound Control and Speak-to-Chat
Sony's Adaptive Sound Control is the feature that genuinely separates the LinkBuds S from the competition in everyday use. Unlike AirPods Pro 2's manual transparency/ANC toggle, Adaptive Sound Control uses your phone's GPS and motion sensors to identify your activity — commuting, walking, staying still — and automatically shifts the noise cancellation profile. After a week of use, it learns your frequently visited locations (home, office, gym) and applies your preferred settings automatically at each location. Speak-to-Chat works in the opposite direction: the moment you start speaking to someone, the earbuds detect your voice and automatically pause music and activate full transparency — no button press, no fumbling. Find more details in our Electronics category page.
Who should buy the LinkBuds S?
- Daily commuters — Adaptive Sound Control is transformative on public transport; ANC activates automatically on the train and fades when you reach your stop
- Office and hybrid workers — at 4.8g, they're comfortable through full workdays; Speak-to-Chat makes quick conversations effortless without removing earbuds
- Spotify and streaming listeners — DSEE Extreme AI upscaling meaningfully improves compressed streaming audio quality in real time
- Active and gym users — IPX4 splash resistance, secure fit, and lightweight design survive sweaty workouts without discomfort
- Android ecosystem users — the Sony Headphones Connect app on Android unlocks the full feature set including Adaptive Sound Control customisation and 360 Reality Audio
- Budget-conscious audiophiles — at $149, the LinkBuds S delivers Sony WF-1000XM4-level audio processing at half the flagship price
Skip the LinkBuds S if maximum noise cancellation is your top priority — the AirPods Pro 2 and Bose QuietComfort Earbuds II offer stronger absolute ANC performance. If you want the longest possible battery life on a single charge, the Galaxy Buds2 Pro's 8-hour single charge outlasts the LinkBuds S's 6 hours. But for the user who wants the most intelligent, adaptive, and comfortable everyday earbuds available under $200 — the Sony LinkBuds S is our clear recommendation.

What we love & what we don't
After two months of daily use across commuting, gym sessions, office work, and travel, here is our honest assessment of the Sony LinkBuds S.
✓ What we love
- Adaptive Sound Control is genuinely magical — no other earbuds at this price intelligently switch between ANC and transparency based on what you're doing; it works correctly over 90% of the time after a week of learning
- 4.8g featherlight comfort — the lightest noise-cancelling earbuds available; after 3+ hours of wear, you genuinely forget they are in your ears
- DSEE Extreme makes streaming sound better — the AI upscaling is not just marketing; Spotify at 320kbps through LinkBuds S sounds noticeably more detailed than without it
- Speak-to-Chat is the most useful earbud feature of the decade — auto-pausing when you speak ends the awkward "hold on" moment of every conversation
- LDAC Hi-Res Audio Wireless — at $149, offering LDAC codec support (Sony's 990kbps Bluetooth codec) is remarkable; AirPods Pro 2 has no equivalent
- Wireless charging case included — Qi wireless charging is standard; AirPods Pro 2 includes it, but many competitors at this price don't
- Multipoint Bluetooth — stay connected to laptop and phone simultaneously; seamlessly switches audio source without re-pairing
- Quick Charge: 5 min = 60 min — the fastest quick-charge ratio of any earbud in this price range
- Google Assistant + Alexa simultaneously — dual voice assistant access in one device; rare at this price
✗ What we don't
- ANC is good, not best-in-class — AirPods Pro 2 and Bose QC Earbuds II offer stronger absolute noise cancellation, particularly against low-frequency drone (plane engines, underground trains)
- 6 hours per charge is below average — AirPods Pro 2 delivers 6 hours, Galaxy Buds2 Pro 8 hours; light users will be fine but heavy users will charge daily
- Bass response is lean — the 5mm driver prioritises midrange clarity and detail retrieval over deep bass; bass-head listeners will prefer Galaxy Buds2 Pro or Bose QC II
- App is Android-first — the Headphones Connect app is significantly more capable on Android than iOS; iPhone users lose Adaptive Sound Control location memory and some EQ features
- Ear tips can loosen during vigorous exercise — the lightweight design is a comfort advantage but reduces secure fit during running; use the smallest tip for sport
- Call quality in wind is mediocre — the 5-mic array handles indoor calls well but wind noise degradation on outdoor calls is noticeable
- No volume control on earbuds by default — volume adjustment requires customising touch controls in the app; not intuitive out of the box
Our verdict: 4.5 stars
The Sony LinkBuds S earns its recommendation not by being the best at any single thing, but by being excellent at everything that matters in daily life. Adaptive Sound Control alone is worth the purchase price. At $149 — currently $50 off — they represent the best value proposition in noise-cancelling earbuds under $200.

What buyers say
21,860 verified reviews from daily users. The LinkBuds S is Sony's highest-rated mid-range earbud of all time on our platform.
Adaptive Sound Control on the Yamanote Line is witchcraft — it just knows
I commute on the Yamanote Line every morning. After five days of wearing the LinkBuds S, Adaptive Sound Control learned my routine completely. ANC ramps to maximum when the train doors close, fades when I approach Shinjuku Station, and switches to full transparency as I walk out the exit. I never touch the earbuds. The Speak-to-Chat feature is the single most useful thing any earbuds have ever done — at the convenience store, I no longer have to remove them to talk to the cashier. The LDAC codec on Mora Qualitas streaming makes my commute sound genuinely hi-fi. At 4.8g I truly forget I'm wearing them. At ¥21,000 these are remarkable value for what Sony has put in.
Wore them for 9 hours straight in a client meeting — never once uncomfortable
I'm a lawyer and spend long days in meetings and calls. I've tried the AirPods Pro 2, Galaxy Buds2 Pro, and Jabra Evolve2. The LinkBuds S are the only earbuds I can wear for a full nine-hour workday without ear fatigue. At 4.8g they simply disappear. The call quality is excellent in quiet conference rooms — my voice comes through clearly on every platform (Teams, Zoom, Meet). Speak-to-Chat was initially alarming — the first time music paused mid-sentence when I started talking I thought something broke. Three weeks in I cannot imagine earbuds without it. The Adaptive Sound Control location memory means ANC activates automatically in my office building lobby and transparency switches on at my desk. Sony has thought this through in a way no competitor has.
LDAC on Tidal HiFi at $149 is an absurd value — sounds like the WF-1000XM5
I'm an audio engineer and test earbuds professionally. The LinkBuds S at $149 with LDAC is genuinely embarrassing for Sony's competitors. The AirPods Pro 2 at $249 doesn't even support Hi-Res Bluetooth — it tops out at AAC (250kbps). The LinkBuds S at LDAC 990kbps connected to Tidal HiFi delivers a soundstage, instrument separation, and treble extension that is genuinely comparable to the WF-1000XM5. The 5mm driver has excellent midrange clarity and controlled highs. Bass response is lean by consumer standards, which I personally prefer for reference listening but casual listeners might find thin. The DSEE Extreme upscaling adds a noticeable layer of air and detail to standard Spotify streams that I wasn't expecting to be this effective. Remarkable engineering at this price.
Switched from AirPods Pro 2 and the only thing I miss is Siri — everything else is better
I used AirPods Pro 2 for 14 months. I switched to the LinkBuds S because my new phone is a Samsung Galaxy S24 and the AirPods experience on Android is noticeably degraded. The LinkBuds S with Headphones Connect on Android is far better than AirPods on Android. Adaptive Sound Control location memory — which AirPods don't have — is the feature I didn't know I needed: my earbuds automatically activate ANC on the Moscow Metro platform and switch to full transparency in the train car. The LDAC codec on TIDAL sounds genuinely better than AAC on AirPods. The ANC isn't quite as strong as AirPods Pro 2 on the underground — there's more low-frequency rumble — but in offices and cafes the difference is minimal. At $100 less, it's the obvious choice for Android users.
Four stars: incredible comfort and smarts, but battery life is the real trade-off
Everything about the LinkBuds S is excellent except the battery life. I commute 90 minutes each way in Mumbai, work 8 hours in an open-plan office, and hit the gym after work. On a heavy day — ANC on throughout — I'm reaching for the case by 7pm. Six hours per earbud is the honest ceiling. The case gives 14 more hours which means the total is fine, but I'd prefer not to interrupt my evening gym session to drop them in the case. For anything under 6 hours of daily use, I'd give this five stars without hesitation. The comfort is transformative — I've had AirPods Pro 2, Galaxy Buds2 Pro, and Jabra 3, and the LinkBuds S are the only earbuds I've ever worn that I genuinely forget are in. Speak-to-Chat has ruined every other earbud for me. Absolute must-buy at $149.
Two years of WF-1000XM4 loyalty ends here — the LinkBuds S does everything better at half the price
I was a devoted WF-1000XM4 user for two years. When they needed replacement, I auditioned the WF-1000XM5 ($280) and the LinkBuds S ($149). The XM5 has better absolute ANC and marginally richer bass. The LinkBuds S has Speak-to-Chat, lighter weight, Adaptive Sound Control location memory, and costs $130 less. For my life — commuting in Edinburgh, office work, evening walks — the LinkBuds S is the more useful product. The Adaptive Sound Control transitions between ANC and transparency when I walk from the Waverley underground to Princes Street are spot-on. The DSEE Extreme upscaling on Apple Music Lossless is genuinely audible. The only thing I've noticed is the ANC doesn't handle the rumble of the Edinburgh trams as aggressively as the XM4 did — but it's close enough. Exceptional value.
Gym earbuds that also handle every work call perfectly — I stopped carrying two pairs
I used to carry Jabra Elite 4 Active for the gym and Sony WF-1000XM3 for work. I switched to LinkBuds S for everything and retired both. The IPX4 rating handles my reformer Pilates classes and runs without issue — the medium ear tips stay put through anything short of sprinting. The call quality on Google Meet and Zoom is clear enough that my clients have never complained. The Sony Headphones Connect app on my Pixel 8 Pro is excellent — the EQ customisation is genuinely usable and the Adaptive Sound Control settings give granular control over exactly when and how each location switches modes. I've also started using the 360 Reality Audio on Apple Music and it's a genuinely different listening experience for orchestral and electronic music. One pair, every use case, $149. No-brainer purchase.
The multipoint Bluetooth works so well I forgot it was there — seamless laptop and phone switching
I work remotely and toggle between video calls on my MacBook and music on my Android phone constantly. The LinkBuds S multipoint connection handles this better than any earbuds I've previously used. Music pauses on the phone automatically when a Teams call starts on the laptop. When the call ends, music resumes on the phone. No re-pairing, no manual switching, no latency. The Headphones Connect app on Android gives access to 360 Reality Audio, which I use with Tidal and it genuinely adds spatial depth to stereo recordings. The Ecru colour I ordered looks clean and professional in video calls — a small detail that matters when your face and ears are on camera daily. At €139 in Europe this is the best value audio purchase I've made in years.
