Introduction

I was on a flight last year sitting next to a guy with the engine roaring in the background.

He just put his earbuds in and looked completely unbothered.

I leaned over and asked what he was using.

He held up the Sony LinkBuds S.

I remembered that moment when a friend asked me to help him pick wireless earbuds recently. I went straight back to researching these.

Here is everything I found.

So What Even Are the Sony LinkBuds S

The LinkBuds S are Sony's all-day true wireless earbuds with active noise cancellation.

They are not the open-ring style of the original LinkBuds.

These look like normal in-ear earbuds but built specifically to be worn comfortably from morning to night without fatigue.

At just 4.8 grams per earbud they are among the lightest ANC earbuds available anywhere.

That weight difference is something you actually feel after wearing earbuds for six or seven hours straight.

The Design and Fit

The shell is small and sits close to the ear.

No big stems hanging down. No chunky housing sticking out.

They come in Black, Ecru, and Earth Blue depending on where you buy.

Four pairs of ear tips in different sizes are included in the box.

Finding the right ear tip matters more than people think with in-ear earbuds.

A proper seal improves both sound quality and noise cancellation performance at the same time.

Active Noise Cancellation

Here is the thing about the ANC on these.

It uses Sony's Integrated Processor V1. The same chip found in the much more expensive WF-1000XM5.

Low frequency noise like airplane engines, air conditioning hum, and car rumble gets cut down dramatically.

In real world testing on flights the ANC performs impressively against sustained droning sounds.

Higher frequency sounds like sharp voices or sudden loud noises do still come through partially.

That is true of basically every earbud ANC system at any price.

The Adaptive Sound Control feature automatically switches between noise cancellation and ambient mode based on what you are doing.

Walking gets ambient mode. Sitting still triggers noise cancellation. No manual switching needed.

Transparency Mode

I want to be real with you here. The transparency mode on these is genuinely impressive.

It lets outside sound in clearly and naturally.

Having a conversation, ordering coffee, or hearing announcements in a station all work without removing the earbuds.

Multiple reviewers specifically called the transparency mode more convincing than competitors in this price range.

For all-day wear that feature matters just as much as the noise cancellation itself.

Sound Quality

The LinkBuds S use a 5mm dynamic driver inside each earbud.

They support SBC, AAC, and LDAC Bluetooth codecs.

LDAC is Sony's high quality codec that transmits up to three times more data than standard Bluetooth audio.

For anyone listening with a compatible Android device the LDAC option brings the audio closer to a wired listening experience.

Bass handling is solid and well-controlled without being overblown.

Midrange performance is decent though some reviewers find it slightly recessed compared to the high end and low end.

360 Reality Audio and DSEE Extreme upscaling are both available through the Sony Headphones Connect app.

One thing worth knowing. DSEE Extreme noticeably reduces battery life when enabled. The audio quality improvement is subtle at best. I would leave it off for daily use.

Smart Features That Actually Work

Speak-to-Chat is one of those features that sounds gimmicky until you use it.

The earbuds detect when you start speaking and automatically pause your music.

When you stop talking music resumes on its own.

No fumbling for a button. No taking the earbuds out mid-conversation.

Quick Attention mode works similarly. Cover the right earbud with your palm and ambient sound comes through immediately without changing any settings.

The earbuds also auto-pause when removed from your ears and resume when you put them back in.

Call Quality

Sony uses Advanced Voice Signal Processing for calls.

The microphones isolate your voice from background noise reasonably well in normal environments.

In very loud or windy conditions call quality does drop noticeably.

Either earbud can be used independently for one-ear monitoring during calls which is useful for office environments or when you need one ear free.

Battery Life

The earbuds themselves provide up to 6 hours of playback with ANC enabled.

The charging case adds another 14 hours bringing total combined playback to around 20 hours.

Quick charging gives 60 minutes of playback from just 5 minutes in the case.

The case charges via USB-C.

One thing to flag. Running LDAC at full 990kbps bitrate drops earbud battery life to around 4 hours instead of 6.

If battery life matters more to you than maximum audio quality, using AAC gives significantly longer listening time.

The Sony Headphones Connect App

The app is available free for both iOS and Android.

It handles EQ adjustments, sound mode controls, touch control customization within limits, and firmware updates.

Here is the part that frustrates some people.

Touch control customization is limited compared to competitors.

You can assign functions to each earbud at a general level but cannot customize individual gesture actions the way some rival apps allow.

It is a real limitation for people who like full control over their earbuds.

How to Maintain Your Sony LinkBuds S

Wipe the earbuds down with a soft dry cloth after workouts or heavy use.

Do not use water or cleaning liquids directly on the earbuds even though they are IPX4 rated.

IPX4 means splash and sweat resistance. Not submersion. Not rinsing under a tap.

Clean ear tips with a slightly damp cloth and dry them fully before reattaching.

Store them in the charging case when not in use.

Keep the charging case contacts clean so charging stays reliable over time.

Customer Reviews

Buyers consistently praise the comfort for extended all-day wear.

The lightweight design at 4.8 grams per earbud gets repeated mentions from people who had discomfort with heavier earbuds before.

Transparency mode gets strong positive feedback from commuters, office workers, and people who need situational awareness throughout the day.

Some buyers flag that ANC performance is not best-in-class against the very top competitors at similar prices.

A few reviewers mention limited touch control customization as a frustration after extended use.

Overall ratings lean positively. Most buyers describe them as the most comfortable all-day earbuds they have owned.
