Frequently Bought Together
Small and light for all-day comfort
Approximately 0.17 ounces in weight, LinkBuds S is the world's smallest and lightest, noise canceling, Hi-Res truly wireless headphones.1 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-canceling 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 canceling
These earbuds give you the best of both worlds-Sony's best transparent ambient sound in truly wireless headphones2 when you want to interact with your world, high-quality noise canceling when you need to focus. LinkBuds S automatically switches between Ambient Sound Mode and noise canceling 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 behavior and recognizes locations that you frequently visit, such as your workplace or a favorite café, and tailors sound to suit the situation.Sony's best ever call quality in truly wireless headphones3
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 0.2" 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 enables clear reproduction of voices in music, movies and podcasts. And with enhanced noise canceling, 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 data4 than conventional Bluetooth® audio5 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.6.Total convenience, total customization
LinkBuds S are even better with the Sound Connect app. The simple, intuitive interface lets you dial in your ideal sound and shortcut settings, and can keep track of your recent listening history. Safe Listening even lets you check you're in line with WHO healthy listening habits.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.7, 6.Control with your voice
Get hands-free help-Just say "Hey Google" or "Alexa" to activate your preferred voice assistant.6 Listen to music, connect with friends, get notifications, set reminders, and more. You can even control your headphones features like noise cancellation with your voice8, listen to and interact with emails in Microsoft Outlook, and join Microsoft Teams meetings using Google Assistant or Siri.9.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 hours17 of listening every time you leave the house. In a hurry? Just 5 minute quick charging gives you up to 60 minutes of play time, and the Sony | Sound Connect app will even notify you when your charging case drops below 30%.360 Spatial Sound Personalizer
With the Sony | 360 Spatial Sound Personalizer app18, you'll enjoy a sound experience that's optimized for you. The app captures and analyzes your ear shape, allowing these headphones to create your own personal spatial sound field when paired with BRAVIA XR TVs.19, 20.Earth Blue-Made from recycled materials22
Parts of the body and case of LinkBuds S in Earth Blue are made from factory-recovered plastic and reclaimed water bottles23, 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.Every pair helps the 'Protect our Oceans' project
Not only are we cutting the amount of virgin plastic used, but also the amount of USD $2 of the sales price of each unit sold will be donated to support Conservation International's ocean conservation activities. This means every purchase will protect nearly 633,176.27 square feet of ocean, an area equivalent to about 47 Olympic-sized swimming pools.24, 25.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.26.Size & Weight | |
