Sony LinkBuds S Truly Noise-Canceling Wireless Earbuds - WFLS900N/B

What’s your colour?

Make it personal with a choice of four premium matte colours—including blue-marble colour Earth Blue—all with matching case.

Small and light for all-day comfort

Approximately 4.8 grams in weight, Linkbuds S are the world’s smallest and lightest, noise-cancelling, Hi-Res truly wireless headphones. We’ve kept the size down by developing a compact driver and integrating the Bluetooth® Audio SoC (System on Chip) and high-quality noise-cancelling processor in one single chip. It’s 40% smaller than the WF-1000XM4.　

Comfortable and secure

LinkBuds S combines a shape that perfectly matches the human ear with an ergonomic design for a more stable fit. We’ve designed LinkBuds S utilizing extensive ear shape data collated since introducing the world’s first in-ear headphones in 1982, as well as evaluation of the sensitivity of various types of ears to ensure an ideal shape that is comfortable for many people.

Transparent ambient sound or high-quality noise cancelling

These earbuds give you the best of both worlds—Sony’s best transparent ambient sound in truly wireless headphones when you want to interact with your world, high-quality noise cancelling when you need to focus. LinkBuds S automatically switches between Ambient Sound Mode and noise cancelling depending on where you are and what you’re doing.

Adjusts ambient sound to whatever you do for all-day wearing

Adaptive Sound Control is a smart function that senses where you are and what you’re doing, then adjusts ambient sound settings for the ideal listening experience. Over time, it learns your behaviour and recognizes locations that you frequently visit, such as your workplace or a favourite café, and tailors sound to suit the situation.

Sony’s best ever call quality in truly wireless headphones

With Precise Voice Pickup Technology that optimally controls microphones on the outside and inside of the earbud, and advanced audio signal processing, conversations are ultra-clear, even in noisy environments. Our noise-reduction algorithm was developed with AI machine learning using over 500 million voice samples to suppress ambient noise and extract your voice clearly.

Minimizing wind noise

Even on windy days, you’ll stay comfortable with wind noise minimized by a mesh structure around the microphone. 

Immersive sound, authentic music

A new 5 mm driver unit featuring a high-compliance diaphragm helps keep LinkBuds S small. Despite its size, it reproduces powerful bass and crystal-clear vocals, bringing out the best in all music genres. Rich mid-range sound gives clear reproduction of voices in music, movies and podcasts. And with enhanced noise cancelling, LinkBuds S provides less distractions too.

Integrated Processor V1

Improves noise cancelling for distraction-free listening with less power, enhances sound quality and reduces distortion.

Enjoy High-Resolution Audio without wires 

LinkBuds S supports High-Resolution Audio Wireless thanks to LDAC, our industry-adopted audio coding technology. LDAC transmits approximately three times more data than conventional Bluetooth® audio allowing you to enjoy High-Resolution Audio content in exceptional quality, as close as possible to that of a dedicated wired connection.

Real-time restoration of all your compressed files 

Using Edge-AI (Artificial Intelligence), DSEE Extreme™ upscales compressed digital music files in real time. Dynamically recognizing instrumentation, musical genres and individual elements of each song, it restores high-range sound lost in compression.

Listen safely with Sony | Headphones Connect app

Check how safely you’re listening to music by comparing sound pressure data recorded by your headphones with guidance of the World Health Organization (WHO). Receive OS notifications when listening levels are too high. LinkBuds S also feature intuitive touch control settings. You can assign your own functions to each earbud using the Headphones Connect app.

Talk and hear only ambient sound

You can set Speak-to-Chat to automatically pause the music as soon as you speak to someone, so you can hear just ambient sound and conduct a conversation—handy if you want to keep your headphones on or your hands are full. And once your chat is over, your music starts playing again automatically.

Instant pause. Instant play.

Just take the earbuds out of your ears and the music stops—a proximity sensor knows when you are wearing one or both earbuds. Pop the earbuds back in and the music starts again.

Control with your voice

Get hands-free help—Just say “Hey Google” or “Alexa” to activate your preferred voice assistant. Listen to music, connect with friends, get notifications, set reminders and more. You can even control your headphone features like noise cancellation with your voice, listen to and interact with emails in Microsoft Outlook and join Microsoft Teams meetings using Google Assistant or Siri.

Everything’s at your fingertips

LinkBuds S features intuitive touch control settings—for example, tap on the left earbud to change from Noise Cancelling to Ambient Sound and long tap for Quick Attention, or double tap on the right to skip to the next track.

Quick access to your favourite music and soundscapes

With Quick Access, you can configure these wireless earbuds to resume Spotify music playback or Endel personalized soundscapes with two or three taps—no need to touch your smartphone. 

Find your headphones with Fast Pair

LinkBuds S supports Google’s helpful new Fast Pair feature. It lets you easily locate where you left your headphones by tone sound, or checking their last known location in Google’s Find My Device app on your smartphone.

Easy pairing with your computer

Swift Pair makes it quick and easy to pair your headphones with your Windows 11 or Windows 10 laptop, desktop PC or tablet. Pop-up pairing guidance appears on nearby Windows 11 or Windows 10 devices when pairing mode is selected.

Next-generation Bluetooth audio

A clearer, more stable Bluetooth signal

For low latency and high sound quality, even around other interference, the Bluetooth® signal is transmitted to both ears at the same time. Thanks to the powerful Integrated Processor V1, you’ll enjoy stable, skip-free, wireless sound.

Recycled plastic materials

Listen all day, charge in minutes

You can enjoy a full working day of charge—6 hours—from your headphones and store another 14 hours in the case. That means a full 20 hours of listening every time you leave the house. In a hurry? Just 5 minutes of quick charging gives you up to 60 minutes of play time, and the Sony | Headphones Connect app will even notify you when your charging case drops below 30%.

Ultra-small case, a perfect match

Now available in Earth Blue

Made from recycled materials, LinkBuds S are now available in a distinctive blue marble-patterned colour—Earth Blue.

Earth Blue—Made from recycled materials

Parts of the body and case of LinkBuds S in Earth Blue are made from factory-recovered plastic and reclaimed water bottles, in addition to recycled plastic materials from automobile parts. This gives them their characteristic marble pattern. Inevitable variations in the marble pattern mean that no two pairs of LinkBuds S in Earth Blue are quite the same.

Multipoint connection

For total convenience, these Bluetooth® headphones can be paired with two Bluetooth devices at the same time. So when a call comes in, your headphones know which device is ringing and connect to the right one automatically. You’ll also be able to quickly switch your headphones to either of the two devices at the touch of a button.
