The Sony WH-CH520 are wireless on-ear headphones designed for music playback and calls. They are equipped with 30 mm drivers and feature a closed acoustic system. The headphones incorporate Digital Signal Processing (DSEE) technology, which is intended to restore high-frequency elements to compressed digital audio files. Connection to source devices is established via Bluetooth 5.2, which supports A2DP, AVRCP, HFP, and HSP profiles for audio streaming and communication.
The internal lithium-ion battery provides up to 40 hours of continuous audio playback or talk time from a full charge. Recharging is handled through a USB Type-C port, with a full cycle taking approximately 3 hours; a fast-charging function is also available. Onboard button controls are integrated into the earcup for managing volume, track selection, and calls. The unit has a lightweight plastic construction, weighing 147 grams, and includes a built-in microphone for hands-free functionality.
