Sony WH-CH520 Wireless On-ear Headphones, White

The Sony WH-CH520 are on-ear wireless headphones designed for music and calls. They are equipped with 30 mm drivers that operate within a frequency response range of 20 Hz to 20,000 Hz. The closed acoustic design helps to isolate sound, and Digital Signal Processing (DSP) is used to manage the audio output. Connectivity is handled through Bluetooth 5.2, which maintains a stable connection up to 10 meters from the source device. The lightweight 147-gram build incorporates a plastic headband and padded ear cushions.

The internal lithium-ion battery delivers a substantial operational time, rated for up to 50 hours of audio playback or 40 hours of talk time. A full charge is completed in three hours using the included USB-C cable, with a 10-minute fast charge function available for quick power. On-device buttons provide direct control over volume, track selection, and call management. For voice input, the headphones feature a single built-in microphone and offer direct access to mobile operating system voice assistants. The device supports multiple Bluetooth profiles, including A2DP and AVRCP, along with AAC and SBC codecs.
