Overview

The Sony LinkBuds Fit (WFLS910N) are truly wireless earbuds engineered around the idea that comfort should never be a compromise. Sony's newly developed Air Fitting Supporters cradle each earbud securely in the ear without the pressure or fatigue that plagues many in-ear designs, making them well suited for long listening sessions, workouts, and daily commutes alike. Despite their small, lightweight form factor, they pack Sony's active noise cancellation technology to suppress background noise and an improved Ambient Sound Mode that lets you tune back into your surroundings when needed—toggling between isolation and awareness with a simple touch.

Under the hood, Bluetooth 5.3 provides a stable, efficient wireless connection, and multipoint pairing allows simultaneous connection to two devices so you can take a call on your phone without disconnecting from your laptop. The earbuds deliver up to 5.5 hours of playback per charge, while the included USB-C charging case extends that to roughly 15.5 hours total. IPX4 water resistance handles sweat and the occasional rain shower. In the box, Sony includes multiple sizes of both Air Fitting Supporters and soft earbud tips, so most ear shapes should find a comfortable, isolating seal. For users who prioritize wearing comfort alongside capable noise cancellation and modern wireless features, the LinkBuds Fit represent a well-rounded option in Sony's truly wireless lineup.
