Shattering expectations of what you can expect from tiny headphones, the Sony WF-LS900N LinkBuds S deliver big.

The world’s smallest and lightest*
The Sony WF-LS900N are the world’s smallest and lightest, noise-cancelling, Hi-Res, Truly wireless headphones. At just 4.8 grammes in weight, you’ll hardly even notice you’re wearing them.
* As of March 30th 2022. According to research by Sony Corporation, measured using Strategy Analytics guidelines in the Truly Wireless style supporting noise cancelling and compatible with LDAC headphones market. LDAC is a certificated codec of "Hi-Res Audio Wireless"

Comfortable fit
More than just small and light, these Sony LinkBuds S headphones are supremely comfortable, too. Using ear-shape data collected since 1982, Sony are in the best positon to design the most ergonomically optimised and comfortable in-ear headphones, for the greatest variety of ear shapes.

Automatically switches between ambient sound and noise-cancelling
The WFLS900N headphones intuitively switch between Ambient Sound Mode and noise cancelling, depending on where you are. Adaptive Sound Control detects whether you’re walking, traveling or stationary and then adjusts the ambient sound settings to suit – automatically.

Crystal-clear sound quality
Although small, the advanced, 5mm speaker drivers deliver a rich, powerful sound with articulate vocals and a crisp top-end. Coupled with the noise cancelation, you’ll hear finer details that would otherwise be hard to detect.

The best sound - wirelessly
With their LDAC wireless audio system, these Sony Bluetooth headphones are able to receive around three times more detail than ordinary Bluetooth headphones. This means that all your High-Resolution music files are played to perfection, without the need for a cabled connection.

Clearer calls
Using microphones on the inside and outside of the earbud, combined with advanced signal processing, your voice comes across loud and clear to your caller. The smart noise reduction system uses sophisticated AI machine learning to suppress ambient noise and lets you be clearly heard – even in noisy environments.

Speak-to-Chat and smart playback
Speak-to-Chat automatically pauses the music when you start a conversion – such as ordering a coffee – so you don’t have to remove your headphones. When you do remove them, a proximity sensor knows when you’re wearing one or none and stops the music accordingly. Pop these Sony Bluetooth earbuds back in and the music resumes.

Intuitive touch control
It’s easy to keep control of your Sony wireless earbuds, with simple touch control. Tap on the left earphone to change from noise cancellation to Ambient Sound settings, for example. The right earphone responds by skipping tracks.

Long battery life and quick charge
With 6 hours of battery life, these Sony LinkBuds last the distance. Once you’ve used up the batteries, simply pop them in their case and dip into a further 14 hours playback, giving a total of up to 20 hours. Forgotten to charge your headphones the night before? Don’t fret, as a quick 5 minute charge is all you need for 60 minutes playback.

The ideal partner for your workout
Not only do these LinkBuds fit securely, the IPX4 rating means that they’re also resistant to splashes and sweat. This makes them ideal for jogging or your regular workout.

Enjoy big sound from the smallest around, with the game-changing Sony WF-LS900N LinkBuds S earphones.
