The Sony WH-CH520 is a lightweight on-ear wireless headphone with a built-in microphone, rated for up to 50 hours of playback per charge and quick top-ups when time is short. It supports 360 Reality Audio on compatible tracks and apps, and Sony's sound tuning favors balanced mids and crisp highs with a modest bass lift. It suits commuters, remote workers and students who want long battery life and an easy fit without paying for noise cancellation. Against rivals in its class it gives up active noise cancellation and a case, but its battery rating and light clamp are the main draws; owners describe it as comfortable for hours and easy to live with.
