Some headphone purchases begin with a long feature list. The Sony WH-CH520 makes more sense when the brief is shorter: music, calls and fewer charging interruptions. Its light-looking on-ear form is easy to picture beside a laptop or in a daily bag, but comfort—not the battery headline—is the buying question to settle first.
Where the simple design earns its place
Sony rates battery life at up to 50 hours under its test conditions. That is a useful reason to shortlist it for ordinary routines, not a guarantee of your exact listening time. Multipoint connectivity can also reduce the friction of moving between a phone and computer. Check the manufacturer’s setup instructions for your devices rather than assuming every app will switch perfectly.
Physical buttons let you control playback without relying entirely on a phone screen. The companion app offers sound adjustment, but it cannot turn the headphones into an active noise-cancelling model. The black version shown here is WH-CH520/B, not the similarly named WH-CH720N.
Try the ears, not just the specification sheet
The cushions rest on the ears. If glasses, pressure or long listening sessions already make on-ear headphones uncomfortable for you, a familiar comfortable design is a better bet than a bigger battery number. There is no analogue cable option to rescue a depleted battery or connect to an old audio socket.
Shortlist these for uncomplicated wireless listening in reasonably quiet places. Look elsewhere if your main need is isolating a loud commute or plugging into wired equipment. Our assessment uses manufacturer information and reference images; we have not measured battery life or tested the sound.
