Sony WH-CH520 Wireless On-Ear Bluetooth Headphones with Microphone

When you’re looking for a pair of everyday wireless headphones, the list of things you want is usually pretty straightforward: dependable battery life, a comfortable fit, and easy connectivity. The Sony WH-CH520 aims to check those boxes in a lightweight on-ear design that’s meant to travel with you—whether that’s across town or across the country. With a focus on long playtime and practical features like multipoint connection and quick pairing, these headphones are positioned as a solid choice for people who want a no-fuss listening experience without a lot of extra bulk.

Design & Build Quality

The WH-CH520 is an on-ear headphone with a design that leans toward simplicity and portability. The lightweight build is one of the first things that stands out, and it’s a key part of the comfort story here. Sony describes the headphones as light and comfortable, with swivel earcups that are meant to slip on and off easily. That swivel design also makes it easier to store the headphones flat or hang them around your neck when you’re not actively listening.

The adjustable headband and cushioned ear pads are designed to provide all-day comfort, which matters if you’re planning to wear these for long stretches—like during a workday or a long commute. The soft ear pads are a notable detail, as they’re the main point of contact between the headphones and your ears. While the on-ear form factor won’t envelop your ears the way over-ear models do, the padding is intended to keep things comfortable for extended sessions.

Color options are another part of the design story. The WH-CH520 is available in six colors: Black, Blue, White, Pink, Yellow, and Cappuccino. The black model reviewed here is the most understated option, but the range gives you room to pick something more expressive if that’s your style.

Features & Technology

One of the more interesting features on the WH-CH520 is the inclusion of DSEE (Digital Sound Enhancement Engine). This technology is designed to boost the quality of compressed music files, which is a practical benefit if you listen to streaming services or have a library of older, lower-bitrate tracks. The idea is that DSEE helps restore some of the detail that gets lost during compression, so your music can sound fuller and more polished. It’s not a claim that the headphones will transform your audio, but rather that they’re equipped to handle compressed files more gracefully than a pair without this processing.

You also get EQ Custom through the Sony | Headphones Connect App. This lets you adjust the sound to match your music preferences rather than being stuck with a single factory tuning. The app-based EQ is a nice touch for listeners who like to tweak their audio profile—whether you want more bass, clearer vocals, or something in between. The fact that this customization is available means the headphones can adapt to different genres and listening habits, at least to the extent that the hardware allows.

Another feature worth noting is the multipoint connection, which allows you to switch between two devices at once. This is a practical feature for people who juggle a phone and a laptop, for example. Instead of disconnecting and reconnecting every time you want to switch from a video call on your computer to music on your phone, the headphones are designed to handle both connections simultaneously and let you move between them quickly.

Performance & Everyday Experience

When it comes to everyday use, the WH-CH520 is built around convenience. The built-in microphone enables hands-free calling, so you can take calls without pulling your phone out of your pocket. This is a straightforward feature, but it’s one that makes the headphones more versatile—they’re not just for music, but also for staying connected throughout the day.

The quick charging feature is another practical element. With up to 50 hours of battery life on a full charge, you’re looking at multi-day use without needing to plug in. That kind of endurance is aimed at people who don’t want to think about charging every night—whether you’re on a road trip, at a festival, or just have a busy week ahead. The USB Type-C cable is included, which is a convenient modern standard, and the quick charging aspect means even a short charging session can get you back up and running when you’re in a pinch.

Finding your headphones is another area where the WH-CH520 offers a practical solution. Using Google’s Find My Device app on your smartphone, you can locate your missing headphones by sound or check their last known location. This is a genuinely useful feature for anyone who’s ever misplaced their headphones at home or while traveling. It doesn’t guarantee you’ll always find them, but it gives you a way to track them down that you wouldn’t have with a standard pair of Bluetooth headphones.

Connectivity & Compatibility

Bluetooth pairing is handled with an eye toward ease of use. The headphones support Fast Pair, which is designed to make the initial connection to your smartphone quick and straightforward. If you’re an Android user, this is a feature that can save you the hassle of digging through Bluetooth settings and manually searching for the device.

For Windows users, there’s Swift Pair support, which brings similar convenience to pairing with a Windows 10 computer. This is a nice addition for people who split their time between a phone and a PC. The multipoint connection mentioned earlier also plays into this, as it means you can keep both devices paired and switch between them as needed.

It’s worth noting that the Fast Pair feature is tied to Google’s Find My Device ecosystem, which means it’s designed for use with Android smartphones. The Swift Pair feature is specific to Windows 10. If you’re using other operating systems or devices, the standard Bluetooth pairing process should still work, but the quick-pair conveniences are aimed at those specific platforms.

Who Is This Product Best For?

The Sony WH-CH520 is best suited for listeners who value battery life and straightforward connectivity over premium features like active noise cancellation or high-end audio codecs. The 50-hour battery life makes these headphones a strong candidate for frequent travelers, commuters, or anyone who forgets to charge their devices regularly. The lightweight, comfortable design also makes them a reasonable choice for all-day wear, whether you’re working, studying, or just moving around.

The multipoint connection and hands-free calling features make these headphones practical for people who need to stay connected across multiple devices. If you regularly switch between a phone and a laptop for calls, meetings, and music, the ability to pair with both at once is a real convenience. Similarly, the Fast Pair and Swift Pair support will appeal to Android and Windows users who want a quick, painless setup experience.

On the other hand, if you’re looking for a pair of headphones with active noise cancellation or a fully over-ear design, the WH-CH520 isn’t positioned to fill that role. It’s an on-ear model with a focus on comfort, battery life, and practical features—not on blocking out the world around you.

Final Verdict

The Sony WH-CH520 delivers a well-rounded package for anyone in the market for a lightweight, wireless on-ear headphone. The standout feature is clearly the battery life, with up to 50 hours of playback and quick charging support that makes it easy to keep the music going. The comfort-focused design, including the swivel earcups and soft ear pads, supports extended listening sessions, while the built-in microphone adds hands-free calling capability.

The inclusion of DSEE and EQ Custom via the Sony | Headphones Connect App gives you some control over the sound, and the multipoint connection makes it easy to juggle multiple devices. The Fast Pair and Swift Pair support are thoughtful additions for Android and Windows users, and the Find My Device integration is a practical safety net for the absent-minded.

There’s no single feature here that’s going to blow you away, but the WH-CH520 is a solid, dependable option that covers the basics well. It’s a straightforward choice for listeners who want a comfortable, long-lasting pair of wireless headphones with useful connectivity features—and a color option that fits their style.
