Sony Wireless Noise Cancelling Headphones

The Sony WH-CH520/BZ are wireless on-ear headphones optimized for long battery life, stable Bluetooth connectivity, and app-based sound customization. The headphones employ Sony’s DSEE upscaling to improve the perceived fidelity of compressed tracks and allow users to fine-tune frequency response through the Sony | Headphones Connect application. With an ultra-long runtime of up to 50 hours, USB-C charging and fast-charge capability, the WH-CH520 suits heavy daily use and travel. The compact, closed-back on-ear design yields passive noise attenuation but the model does not include active noise cancellation — the acoustic design and cushions provide comfort and a degree of isolation rather than ANC processing.

Key Feature:

• Up to 50 hours battery life on a single charge with quick-charge capability (3 min charge ≈ 1.5 hr playback).

• DSEE (Digital Sound Enhancement Engine) to restore detail to compressed audio files; adjustable sound via Sony | Headphones Connect app (EQ presets and Graphic EQ).

• Clear call performance with a built-in microphone and enhanced call handling; supports multipoint / quick pairing functionality for smooth device switching.

• No Active Noise Cancellation (ANC) — passive isolation only; designed to be cost-efficient and lightweight rather than ANC-focused. (Important: despite some listing titles, this model does not include ANC.)
