Sony WH-CH520 Wireless On-ear Headphones, Blue

The Sony WH-CH520 are on-ear wireless headphones equipped with 30mm dynamic drivers that cover a 20-20,000 Hz frequency range. They incorporate Sony's Digital Sound Enhancement Engine (DSEE), a technology that works to restore high-frequency detail that is often lost in compressed digital audio files. Connectivity is handled via Bluetooth 5.2, which provides a stable wireless link to compatible devices for both music playback and calls. The closed acoustic design contributes to passive sound isolation from the surrounding environment.

These headphones provide up to 40 hours of continuous audio playback on a single charge. Recharging is completed in approximately three hours through a USB-C port, and a fast-charge function provides additional listening time from a 3-minute charge. The construction is lightweight at 147 grams, intended for extended use. On-device buttons allow for direct management of volume, track selection, and call functions, while a built-in microphone facilitates hands-free calling.
