Sony WFL900W.CE7 Linkbuds Headset True WFL900W.CE7

Keep every world on
LinkBuds connect all your worlds perfectly with an open ring design that allows you to hear calls, music and other online content anytime, as well as the ambient sounds around you transparently, feeling nothing on your ear. Small and light with super fit styling for hours of comfortable wearing, they ensure you're always connected to your life, so you'll never miss a thing.

Super small and light
Approximately four grams in weight and extremely small, LinkBuds are a marvel of miniaturisation. Unlike conventional earbuds, the protective surface covering the speaker diaphragm is integrated within the housing, saving space.

Comfortable and secure fit
LinkBuds combine a shape that perfectly matches the human ear with an ergonomic design for a more stable fit. We�ve designed LinkBuds utilising extensive ear shape data collated since introducing the world�s first in-ear headphones in 1982. See our �How to� video for better wearing and listening.

Connected and aware
A newly developed ring-type driver unit with the centre of the diaphragm open for audio transparency allows you to clearly hear the sounds around you. So, you'll hear when someone calls your name during a call and can chat with friends while listening to music.

Ultra clear, noise-free calls
With precise voice pickup technology with advanced audio signal processing, the person on the other end of the call will hear your voice clearly, even when you are in noisy situations. Our noise reduction algorithm was developed using AI machine learning using more than 500 million voice samples to suppress ambient noise and extract your voice clearly in a wide range of environments.

Authentic, natural sound
Enjoy well balanced, high quality sound with a clear mid-high range. Our Integrated Processor V1 reproduces all the detail in your music with minimal distortion for an authentic listening experience. A specially designed 12mm ring driver with a high compliance (low recoil) diaphragm provides rich, well-balanced sound.

Give your favourite music a boost
When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. Our Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high-quality sound that�s closer to the original recording.

Simply tap near the ear
LinkBuds may be small but that doesn't mean they're difficult to use. With Wide Area Tap, you can use double or triple taps in front of either of your ears to control your music playback � so there�s no need to touch the LinkBuds themselves to operate

Automatically adjusts sound volume to your environment
Adaptive Volume Control is a smart function that automatically optimises volume based on where you are. Enjoy lower volume in quiet places and higher volume in noisier environments

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. This is based on Precise Voice Pickup Technology, with advanced audio signal processing.

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

Control with your voice
Get hands-free help. Just say �OK Google� or �Alexa� to activate your preferred voice assistant. Enjoy entertainment, connect with friends, get information, listen to music and notifications, set reminders, and more. You can even control your headphones� features like checking out the remaining battery level with your voice. You can also listen to and interact with your emails in Microsoft Outlook and join Microsoft Teams using Google Assistant or Siri.

Find your headphones with Fast Pair
LinkBuds support Google�s helpful new Fast Pair feature. In one tap of pop-up guidance, LinkBuds enable quick, effortless Bluetooth pairing with your Android devices. You can easily locate where you left your headphones by ringing them or checking their last known location on your smartphone. You�ll even receive a notification when your headphones battery is running low, so you know when to charge them.

Easy pairing with your computer
Swift Pair makes it quick and easy to pair your LinkBuds 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.

Quick access to your favourite music
With Quick access, you can configure LinkBuds to resume Spotify playback with just a couple of taps � no need to touch your smartphone.

Recycled plastic materials
LinkBuds use recycled plastic materials from automobile parts.

No plastic in individual packaging
No plastic is included in the packaging material for LinkBuds, reflecting Sony�s commitment to reducing the environmental impact of our products

Water resistant for everyday use
With an IPX4 water resistance rating splashes and sweat won�t stop these headphones � so you can keep on moving to the music.

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. (A) Conventional L to R Relay BT Transmission. (B) LinkBuds L/R Simultaneous BT Transmission.

Listen all day, charge in minutes
You can enjoy a full working day of charge � 5.5 hours � from your headphones and store another 12 hours in the case. That means a full 17.5 hours of listening time every time you leave the house. In a hurry? Just a 10 minute quick charge gives you up to 90 minutes of play time, and the Sony | Headphones Connect app will even notify you when your charging case drops below 30%.

Small, perfectly formed case
Ultra-small with a stylish rounded design, the charging case fits comfortably in your hand or pockets for life on the go. Open with a simple button press.

What's in the box
Open up the packaging for your LinkBuds and you�ll find 5 sizes of arc support to suit different ear shapes and a USB-C charging cable.

So immersive. So real.
Immerse yourself in sound all around you. As real as if you are there at a live concert or with the artist recording in a studio. With 360 Reality Audio, music has never been so immersive and so real. These headphones let you enjoy 360 Reality Audio.
