About this item

Small and light for all-day comfort - Approximately 4.8 grams in weight, Linkbuds S is the world‘s smallest and lightest, noise cancelling, 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.

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.

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.

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.

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

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.
