Sony WH-CH520 Wireless On-ear Headphones, Black

The Sony WH-CH520 are on-ear wireless headphones equipped with 30 mm drivers. They feature Sony's Digital Sound Enhancement Engine (DSEE) technology, which is designed to restore high-frequency detail often lost in compressed digital audio files. The lightweight, 147-gram construction and adjustable headband are intended for comfort during extended listening sessions. Connectivity is established through Bluetooth 5.2, providing a stable wireless connection with a range of up to 10 meters and support for both SBC and AAC audio codecs.

The internal battery provides up to 50 hours of continuous audio playback or 40 hours of talk time. A full charge is completed in approximately three hours via the USB-C port, and a fast-charge function is available for short power top-ups. For calls, a built-in microphone with noise-reduction technology works to isolate the user's voice from ambient sounds. Physical buttons located on the earcup allow for direct control of music playback, volume adjustment, and activation of a connected device's voice assistant.
