Key Performance Upgrades
Monumental 50-Hour Battery Reserve
The absolute standout feature of the WH-CH520 is its class-leading power efficiency. The internal battery cell yields a staggering 50 hours of continuous wireless playback on a single charge. If you discover the battery completely flat right before heading out the door, a highly optimized fast-charge circuit delivers a full 1.5 hours of extra playtime from just a quick 3-minute top-off via the USB-C port.
DSEE™ Audio Upscaling and Custom App EQ
Step up to an audio landscape engineered for high fidelity. Driven by punchy 30mm dynamic drivers, the headset features Sony’s proprietary Digital Sound Enhancement Engine (DSEE™). This processor automatically restores high-frequency detail lost during compression to deliver a sound field closer to the original recording. The headset fully integrates with the official Sony Headphones Connect App, letting you move past default tuning to adjust a granular graphic equalizer or toggle custom presets.
Bluetooth 5.2 and Seamless Multi-Point Switching
Enjoy absolute connection stability, longer range, and cross-platform flexibility. The built-in Multi-Point Connection capability allows the headphones to stay paired to two host devices simultaneously. You can seamlessly watch a video or take a meeting on your laptop, and the headset will smoothly shift the audio source to handle an incoming phone call on your smartphone without you touching your wireless settings menus.
