Linkbuds S Truly Wireless Honest Review — Is the Hype Justified?

I've been using the Linkbuds S truly wireless earbuds as my daily drivers for several months now. I bought them to replace an older pair that had grown uncomfortable and to see whether Sony's smaller, lighter approach could deliver great sound and useful noise control in a truly tiny package. After using them on commutes, in the home office, during workouts, on conference calls, and while traveling, here's my honest take on where they shine, where they fall short, and whether the buzz is really justified.

Quick verdict

In short: yes — the Linkbuds S are an excellent choice if you want very light, unobtrusive earbuds with a clear, balanced sound and a great set of software features. What I found was that they strike a compelling balance between comfort and performance, but they do make trade-offs compared with bulkier flagship models. If you prioritize absolute top-tier ANC or thunderous bass, there's better out there; if you want nearly invisible comfort, solid sound, and smart app features, these are worth serious consideration.

How I tested them

I used the Linkbuds S for about four months as my primary pair of earbuds. My testing involved:

• Daily commuting (city buses and trains), where I tested ANC and transparency modes.
• Working from home and long conference calls to evaluate microphone performance and comfort over multi-hour sessions.
• Exercise sessions (light runs and gym) to test fit and sweat resistance.
• Listening on multiple devices — primarily an Android phone (where I used LDAC) and an iPhone (AAC) — to judge codec behavior and app features.
• Comparing them subjectively to my memory of other earbuds in the same range, especially bulkier Sony flagships and one popular competitor with strong ANC.

Design and comfort

One of the first things I noticed was how small and light the Linkbuds S are. Sony clearly prioritized low weight and a compact profile. In my experience, that pays off: after hours of wearing them I rarely felt ear fatigue. The shape sits deeper and more snugly than rounder stems, and the included tips (I tried the standard and foam-like options) give you a few options to tweak the seal.

What I appreciated was how easy they were to forget about. I wore them for long stretches while working from home and didn't get the soreness in the ear canal that I sometimes get from heavier buds. The case is tiny and slipped easily into a pant pocket — convenient for everyday carry.

One thing that bothered me: while they stay put for light runs and gym sessions, I wouldn't trust them for very intense training or outdoor running with lots of movement. I had one or two moments where I adjusted them mid-run. Also, the touch controls are sensitive — occasionally I would pause music when I only meant to adjust the earbud — but the app helps with customization (more on that below).

Sound quality

Sound is where the Linkbuds S surprised me. Out of the box they deliver a balanced, detailed presentation with a focus on mids and clarity. Vocals sound natural and present, which made podcasts and acoustic music very enjoyable. I tend to prefer a slightly warmer sound for pop and electronic music, so I used the Sony Headphones Connect app to tweak the EQ a few times. With a small bass boost, contemporary tracks gained more weight without becoming boomy.

On Android using LDAC, the difference was noticeable: tracks felt a touch more resolved and open compared to AAC on iPhone. That doesn't mean AAC sounded bad — it's perfectly fine for casual listening — but if you're an Android user with high-res audio, LDAC unlocks a clearer top-end and better instrument separation in my experience.

For bassheads, however, I have to be honest: these aren't meant to be subwoofer replacements. Bass is tight and controlled, not overly emphasized. That results in music that sounds more "accurate" but less visceral for genres that rely on slam. For everyday listening and most genres, I preferred the balance.

Noise cancellation and ambient sound

ANC on the Linkbuds S is effective for their size. In office and cafe settings I found the earbuds smoothed out steady background noise — air conditioning hums, distant conversations, and the constant drone of buses — enough to make focus easier. They don't cancel as aggressively as Sony's larger, heavier flagship models, and they don't match the absolute best-in-class ANC I've experienced on bulkier earbuds, but the trade-off is lighter weight and a less "plugged" feeling.

The ambient / transparency mode is one area where I was pleasantly surprised. Sony's processing here is subtle and maintains natural voice quality. When someone speaks to me, I can hear them clearly without fully removing an earbud, which is handy in offices or at home. The adaptive features that automatically adjust ambient levels based on activity worked well overall, though I turned them off at times because I preferred to control the setting manually.

Battery life and charging

Battery life is one of those personal metrics that will vary with volume, codec, and ANC use. In my experience, I got about five to six hours of continuous listening with ANC enabled on a single charge; with the charging case I could reach roughly 18–20 hours total before needing to plug the case in. If I turned ANC off I could push those earbud runtime numbers a bit further.

One practical detail I liked: the case charges via USB-C and is small enough that I carried it in a jacket pocket without noticing it. Quick charging proved useful — a short 5–10 minute top-up gave me an extra hour or so of playback when I was in a hurry. That kind of quick recovery made travel days less stressful.

Call quality and microphone performance

I use earbuds for a lot of calls, and the Linkbuds S handled most conference calls very well. Indoors, my coworkers told me my voice sounded clear and present. The built-in mics pick up speech faithfully, and processing helps reduce steady background noise.

Outdoors is less consistent. On windy days I noticed wind noise could degrade call clarity, and occasionally I had to cup my hand or move to a sheltered spot to be understood. In quieter outdoor settings, things were fine. If you're on many outdoor calls in busy, windy environments, that's something to keep in mind.

App features and customization

Sony's Headphones Connect app is one of the reasons I stuck with these. The app gives you:

• EQ presets and a customizable equalizer — I used this daily to add bass for certain playlists.
• Adaptive Sound Control that attempts to switch ambient/ANC modes based on activity and location; useful, though not always perfect.
• Sound quality options (LDAC on supported Android devices) and firmware update capability.
• Other niceties like the ability to map touch controls and to run a short fit test.

What I found especially helpful was being able to fine-tune the touch controls so they were less likely to trigger accidentally. The app isn't perfect — the UI could be more intuitive in parts — but it adds tangible value and keeps the earbuds current with firmware updates.

Durability and daily use

I've been wearing the Linkbuds S in rain and through sweaty workouts with no issues; they have an IPX4 rating which protected them from splash and sweat in my experience. The case picked up a few scratches after months in a pocket, but nothing that affected function. Build quality feels solid for the size and price bracket.

One small irritation: the glossy finish on parts of the earbuds shows fingerprints and smudges quickly. It's cosmetic, not functional, but it bothered me when I prefer a cleaner look.

Comparison table — How Linkbuds S stack up

Pros & Cons

What I liked

• Comfort: I could wear these for hours without ear fatigue.
• Sound clarity: Vocals and mids are articulate and enjoyable out of the box.
• Size and portability: The case is tiny and very pocketable.
• App features: EQ, adaptive sound control, firmware updates and LDAC (on Android) are big pluses.
• Useful ANC for the size: It reduces steady background noise enough for commuting and office work.

What I disliked

• Not the deepest bass: If you crave heavy, room-shaking low end, these might feel restrained.
• Wind sensitivity on calls: Outdoor call quality sometimes suffered in breezy conditions.
• Touch controls can be fussy: They occasionally mis-trigger unless you tweak them in the app.
• ANC isn't flagship-level: It’s a trade-off for the small footprint — great for many, but not ideal if you fly frequently and want the best isolation.

Buying guide — Is this the right earbud for you?

If you're considering the Linkbuds S, ask yourself these questions based on how I used them:

Do you value comfort and discrete wear over the last bit of noise cancelling?

If yes, you'll appreciate these. I wore them for long workdays and forgot they were in, which is exactly what you'd want if ear fatigue is a concern.

Are you using Android or iPhone?

If you're on Android and can use LDAC, you'll get the most out of the Linkbuds S's high-resolution capabilities. I noticed clearer detail with LDAC. On iPhone the earbuds are still great with AAC, but you won't get the high-res benefit.

How important is bass to you?

These are precise, not bass-monsters. For EDM and bass-heavy tracks I sometimes missed extra punch; for acoustic, jazz, and spoken-word content they excelled. If you want deep, chest-thumping bass without EQ fiddling, consider trying them in-store first.

Will you use them outdoors a lot for calls?

Indoor call quality was very good in my tests; outdoors it was hit-or-miss with wind. If most of your calls happen in controlled environments, they're fine. If you need great outdoor call performance in gusty conditions, look at options with more wind-resistant mic arrays.

Do you need multipoint device switching?

My experience was that switching between devices worked but wasn't as seamless as some competitors. If automatic, instant device switching is critical for your workflow, check whether firmware updates have added or refined that feature for your region and devices before buying.

Price and alternatives

These occupy a strong position: they offer many premium features in a smaller, lighter package than many higher-end earbuds. If ANC is the top priority and you don't mind a larger bud, flagship models might be a better fit. If you want excellent all-around performance, compact size, and good software, the Linkbuds S are an appealing middle ground.

Final thoughts

After months with the Linkbuds S, what I found was a highly polished product that excels at what it sets out to do: deliver comfortable, everyday listening with thoughtful features and very good sound for its size. They aren't the absolute king of noise cancellation or the punchiest earbuds for low-frequency fans, but I was consistently impressed by how little they got in the way of my day while making music, podcasts, and calls sound clean and natural.

In my experience, the hype is largely justified — the Linkbuds S bring together comfort, competent ANC, a pleasing sound signature, and a useful app ecosystem in a small package. If those things match your priorities, these are a buy-worthy choice. If your priorities are maximum ANC or hyper-aggressive bass, then there are alternatives that target those needs more directly.

Ultimately, I kept mine because they solved a practical problem for me: comfortable, reliable earbuds I could wear for long stretches without compromising sound quality or missing out on modern features. For many people reading this, that balance will be the deciding factor.
