This review covers the key characteristics of the WH-CH520, including battery performance, sound customization options, and multi-device pairing capabilities, based solely on the product information provided.

Features and Specifications

The Sony WH-CH520 comes with a set of features centered on battery endurance and sound management. The most prominent specification is the battery life, which is stated to last up to 50 hours on a single charge. For users who are short on time, the headphones also support quick charging, which provides additional playback time from a short charging session. The headphones are charged via the included USB Type-C cable.

On the audio side, the headphones include DSEE (Digital Sound Enhancement Engine) technology. This feature is designed to boost the quality of compressed music files, which allows for an improved listening experience when streaming music from various services. The headphones also offer sound customization through the EQ Custom feature, which is available in the Sony | Headphones Connect App. This allows the user to adjust the sound profile to match their personal music preferences.

In terms of physical configuration, the WH-CH520 is an on-ear design with swivel earcups. The product is described as lightweight, with an adjustable headband and soft ear pads, which are intended to provide comfort during extended wear. The headphones are available in six color options: Black, Blue, White, Pink, Yellow, and Cappuccino.

Design and Connectivity

The design of the WH-CH520 focuses on portability and ease of use. The lightweight build and swivel earcups allow the headphones to slip on and off with minimal effort. The adjustable headband and cushioned ear pads are designed to accommodate different head sizes while maintaining a comfortable fit. The swivel mechanism also contributes to a more compact storage profile when the headphones are not in use.

Connectivity is handled through Bluetooth, and the headphones offer a Multipoint Connection feature. This allows the user to connect the headphones to two devices at once and quickly switch between them. For example, a user could have the headphones connected to both a smartphone and a laptop, toggling between audio sources without needing to disconnect and reconnect. This feature is particularly useful for those who manage both work and personal devices throughout the day.

For PC users, the headphones support Swift Pair, which simplifies the pairing process with Windows 10 computers. This integration allows for a faster and more direct Bluetooth connection setup when using a compatible Windows device.

Audio and Communication Features

The WH-CH520 includes several audio enhancement features that go beyond standard Bluetooth playback. The DSEE technology is included to restore high-frequency sounds that are often lost during the compression of digital music files. This means that when streaming music from services that use compressed formats, the audio quality can be enhanced to a level closer to the original recording.

The EQ Custom feature, accessed via the Sony | Headphones Connect App, provides the user with control over the sound signature. This allows for adjustments to the equalizer settings to suit specific music genres or personal taste, rather than being locked into a single preset sound profile.

Communication is handled by a built-in microphone, which enables hands-free calling. The microphone allows the user to make and receive phone calls without taking the phone out of a pocket or bag. This is a practical feature for those who take frequent calls while commuting, working, or moving around.

Usage and Compatibility

The WH-CH520 is designed for a range of listening scenarios, supported by its long battery life and connectivity options. The 50-hour battery life is suited for multi-day road trips, long festival weekends, or for users who prefer not to charge their headphones daily. The quick charging capability provides a fast power top-up when the battery is running low, ensuring that the headphones can be used again shortly after a brief charging session.

For users who often misplace their items, the headphones offer a Find My Headphones feature. This works in conjunction with Google’s Find My Device app on a smartphone. The feature allows the user to locate the missing headphones by sound, or to check their last known location on a map. This is an added layer of security for a portable item that could easily be left behind.

The Multipoint Connection feature adds to the practical use of the headphones by allowing them to stay connected to two devices simultaneously. This reduces the need to manually switch the Bluetooth connection between a phone and a computer, which is a common hassle with standard wireless headphones.

Product Configuration

The Sony WH-CH520 is offered in six colorways, giving users the option to select a finish that fits their personal style. The available colors include Black, Blue, White, Pink, Yellow, and Cappuccino. The blue variant is the subject of this listing, but the feature set remains consistent across the color options.

The package includes the headphones and a USB Type-C cable for charging. The headphones are compatible with Bluetooth-enabled devices, including smartphones and Windows 10 computers, with the latter benefiting from the Swift Pair feature. The Sony | Headphones Connect App is required to access the EQ Custom sound settings and to use the Find My Headphones feature with Google’s Find My Device app.
