The Sony WH-CH520 headphones are designed to provide accessible, high-quality wireless audio in a lightweight, comfortable on-ear format. With a focus on everyday convenience, these headphones offer a solid blend of battery life, sound performance and feature-set without pursuing premium audiophile elements like active noise cancellation.
Inside the compact frame you’ll find dynamic drivers (approx. 30 mm) that deliver a sound profile tuned for clarity and balance—enough bass presence to satisfy casual listening, with singers and instruments rendered competently across genres. While the design lacks full over-ear isolation, the on-ear structure keeps weight and bulk down, making them ideal for commuting, work-from-home, or general daily use.
Connectivity is handled via Bluetooth 5.2, enabling strong pairing and support for features like Google Fast Pair and multipoint linking—making it easier to switch between two devices seamlessly. The headphones support Sony’s Headphones Connect app, which allows for EQ adjustment and personalization, giving users more control over their listening experience.
One of the standout attributes is the exceptional battery life: you’ll get up to around 50 hours of playback on a full charge, and a quick 3-minute charge gives you approximately 1.5 hours of listening. The 147 g (≈5.2 oz) lightweight build means you can wear them for extended sessions without significant fatigue. The earcups swivel flat for portability, though they do not fully fold and no carrying case is included.
Build quality is functional and clean, with soft ear pads and a modest profile. These headphones aren’t designed for high-end noise-blocking or studio performance, but for users who want a reliable, stylish set of wireless headphones with long battery life, app support and known brand quality, the WH-CH520 offers strong value.
