The Sony LinkBuds WF-L900 are true wireless earbuds that feature an open-ring acoustic design. This configuration allows external sounds to mix with audio playback, which maintains awareness of the user's surroundings. Each earbud is equipped with a 12 mm dynamic ring driver that covers a frequency range of 20 to 20,000 Hz. The lightweight, 4.1-gram construction is designed for extended wear, and multiple fit tip sizes are included to help secure the earbuds in place during use.
Playback and call management are handled through the Wide Area Tap feature, which registers taps on the skin in front of the ear. The earbuds connect via Bluetooth 5.2 and use built-in microphones with noise-reduction processing for voice calls. On a single charge, the earbuds provide up to 5.5 hours of playback, and the included charging case extends total usage to 17.5 hours. The system supports fast charging, and the earbuds have an IPX4 rating for water resistance, making them suitable for daily use.
