Sony On-Ear Headphones WH-CH520

Key specifications

If you want headphones for everyday listening without the bulk of an over-ear design, the Sony WH-CH520 takes a lighter, on-ear approach. Its feature set is aimed at switching between music and calls, with Bluetooth, a built-in microphone, and multipoint connection for two devices.

Battery life is listed at up to 50 hours, and quick charging is included. The headphones also support sound adjustments through the Sony | Headphones Connect app, including EQ Custom, and DSEE for streaming compressed music files. A USB Type-C cable is included.

Who it’s for

These are suited to listeners who want a straightforward pair for commutes, desk time, or a long stretch of background music without reaching for a charger often. For example, you could listen from a laptop while working, then take a call from your cell phone, multipoint is designed to make switching between two connected devices easier. The built-in mic supports hands-free calls, so you don’t have to take your phone out of your pocket.

The lightweight build, adjustable headband, cushioned design, soft ear pads, and swiveling earcups are intended to make them easier to put on, take off, and wear through the day. It suits you if you prefer a compact on-ear fit and value long stated battery life over a more elaborate set of listening features.

On-ear cups rest against the ears rather than surrounding them, so their fit may not work for everyone during extended sessions. You may want to skip it if you specifically want over-ear coverage or need clearly stated noise-canceling features, none are listed here. The maker also describes call clarity as a benefit, but there are no call-quality test results provided.

What’s included

The listed in-box item is a USB Type-C cable. The description does not specify a carrying case or other accessories, so don’t count on those being included. The blue version is the color named for this product, while the broader range is described as including other color choices, that does not change the core features.

Before you decide

Can you adjust the sound? Yes. EQ Custom in the Sony | Headphones Connect app lets you tailor the sound to your music preferences. DSEE is also listed for improving the quality of compressed music files.

Can you connect two devices? The headphones have multipoint connection, which is designed to let you switch between two devices. That could be useful when moving between a computer and phone, though the listing does not describe the exact switching behavior.

How long does the battery last? Battery life is stated as up to 50 hours, with quick charging also listed. Actual listening time can vary with use, and the description does not give a quick-charge time.

Buying verdict

The WH-CH520 makes most sense if your priorities are a lightweight on-ear design, long advertised battery life, app-based EQ, and the convenience of handling calls and two connected devices. Its practical appeal is the mix of everyday listening and device switching, rather than a promise of immersive isolation or a feature-rich premium experience. According to the maker, battery life reaches up to 50 hours, but that figure is not a guarantee for every listening pattern. Choose this pair if an on-ear fit matches your habits, look elsewhere if you need earcups that fully cover your ears or want noise cancellation specified.
