Overview
Sony designed the WH-CH520 as a wireless on-ear headset for all-day listening, with a microphone for hands-free calls. Fast Pair and Swift Pair speed up the first connection on supported phones and computers.
Very long battery life and a short quick charge cover long days away from an outlet. The light plastic body is easy to wear for hours. Without noise cancelling, outside sound still comes through, and the listing offers no wired backup.
Who it's for
Adults, teens and kids who listen to music and take calls on a phone and want to charge rarely. Buyers who need cancelling, a wired option for planes, or a water resistant build should shop elsewhere.
Pros and cons
- Very long battery life
- Quick charge restores hours of playback
- Microphone for hands-free calls

Performance notes
Battery life is the main strength, and a short plug-in restores a useful amount of playback. Sound comes from dynamic drivers in on-ear cups, so fit and seal on the ear shape the bass. With no cancelling, ambient noise passes through on trains and streets.
