All your worlds, connected and optimised

See how LinkBuds S bridges your everyday life with all-day comfort, natural ambient sound or noise cancelling. Plus Adaptive Sound Control and immersive sound quality for music and calls.

Small and light for all-day comfort

Approximately 4.8 grams in weight, Linkbuds S is the world‘s smallest and lightest, noise canceling, Hi-Res truly wireless headphones. We've kept the size down by both developing a compact driver and integrating the Bluetooth® Audio SoC (System on Chip) and high quality noise cancelling processor in one single chip.

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 utilising 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.

Natural ambient sound or high quality noise cancelling

These earbuds give you the best of both worlds - natural ambient sound 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 recognises locations that you frequently visit, such as your workplace or a favourite café, and tailors sound to suit the situation.

Clear calls and immersive sound

Easily connect with the people you know and the content you love. Make ultra clear calls without noise, and listen to great sounding music without distraction.

Ultra clear, noise-free call

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.

Immersive sound, authentic music

A new 5mm 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 genres of music. Rich mid range sound enables clear reproduction of voices in music, movies and podcasts. And with enhanced noise cancelling, LinkBuds S provides less distractions too.

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 recognising instrumentation, musical genres and individual elements of each song, it restores high range sound lost in compression.

Better mobility through technology

Sony and Microsoft have come together to develop technology that helps people better navigate through the world. LinkBuds S support the Microsoft Soundscape app. The unique integration enables innovative experiences for richer 3D audio-based navigation, while sensors embedded in LinkBuds S allow for a true heads-up and hands-free experience.

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 Organisation (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.
