Sony WFLS910NB.UC LinkBuds Fit Wireless Noise Canceling Earbuds

The Sony LinkBuds Fit (WFLS910NB) are truly wireless earbuds engineered around the idea that noise-canceling earbuds should be comfortable enough to wear all day without fatigue. Sony's newly developed Air Fitting Supporters work alongside multiple earbud tip sizes to create a light, secure seal that stays put during commutes, workouts, and long listening sessions alike. Despite their compact size, the earbuds pack dual noise-sensing microphones and Sony's Auto Noise Canceling Optimizer, which continuously analyzes your acoustic environment and adjusts cancellation strength in real time — so the noise reduction is effective whether you're on a noisy train or in a quiet office.

When you need to hear the world around you, the improved Ambient Sound Mode intelligently lets in environmental audio while still filtering unnecessary noise, striking a balance between awareness and listening enjoyment. The earbuds support multipoint Bluetooth, allowing simultaneous connection to two devices — handy for switching between a phone call and laptop audio without manual re-pairing. Battery life totals up to 21 hours with the charging case (5.5 hours in the buds, 15.5 in the case), and the quick-charge feature provides an hour of playback from just five minutes on the charger. IPX4 water resistance ensures durability through sweaty workouts and light rain. Sony's Sound Connect app unlocks further customization, letting you assign different functions to each earbud's touch controls and fine-tune the audio profile to your preferences. The earbuds are also manufactured using recycled plastic materials, reflecting Sony's sustainability commitments.
