Overview
Everything you need to know.
The Sony LinkBuds S Noise Canceling Earbuds, model WF-LS900N, are truly wireless earbuds that combine active noise canceling with an extremely small, lightweight design, allowing listeners to focus on music, podcasts, and calls in busy cafes, offices, and transit while staying comfortable throughout the day. Designed to be worn for long stretches, they switch smoothly between blocking out distractions and letting surrounding sound in, making them well suited to commutes, workouts, and work-from-anywhere routines where awareness of the environment matters as much as immersive sound. The black finish gives the earbuds and their compact charging case a discreet, understated appearance, and each earbud weighs about 4.8 grams, among the lightest noise-canceling earbuds Sony has produced, with an ergonomic shape that sits securely in the ear. The most distinctive feature is Sony noise canceling powered by the Integrated Processor V1, which reduces a wide range of ambient noise, while Ambient Sound mode brings outside voices and announcements in naturally when a conversation or safety awareness is needed. Another standout is high-resolution audio support through the LDAC codec, paired with DSEE Extreme upscaling that restores detail lost in compressed digital music files, so streaming playlists sound fuller and more refined. Battery life reaches up to 6 hours with noise canceling on and up to 20 hours with the charging case, and a 5-minute quick charge provides up to 60 minutes of listening.
