The Sony WH-CH520 Wireless On-Ear Headphones deliver a practical and enjoyable listening experience, combining lightweight comfort with solid audio performance for everyday use. Designed with 30mm drivers, they produce clear, balanced sound suitable for various music genres, and include Sony’s Digital Sound Enhancement Engine (DSEE), which restores detail in compressed audio files for a richer listening experience. While these headphones do not offer active noise cancellation, their on-ear design provides a decent level of passive noise isolation, making them ideal for casual listening in moderately quiet environments.
Comfort is a key focus with the WH-CH520. Weighing just 147 grams, they feature a slim, adjustable headband and cushioned ear pads that allow for extended use without discomfort. The design is compact and foldable, making them easy to carry and store when not in use. Their wireless functionality is powered by Bluetooth 5.2, and they support multi-point connectivity, enabling seamless switching between two connected devices—perfect for taking calls on your phone while listening to music on your laptop.
Battery life is a standout feature, offering up to 50 hours of playback on a full charge, and with quick charging capabilities, just three minutes of charging can provide up to 1.5 hours of listening time. Physical buttons on the earcups give you easy control over volume, playback, and calls without needing to take out your device. Although they lack touch-sensitive controls or advanced noise-cancelling features, the WH-CH520 makes up for it with dependable wireless performance, long battery life, and a customizable audio experience through the Sony Headphones Connect app.
Overall, the Sony WH-CH520 is an excellent option for users looking for affordable wireless headphones with great battery life, comfort, and everyday functionality, making them ideal for students, commuters, and casual music listeners alike.
