Sony WH-CH520 Wireless Headphones

Everyday Wireless Sound That Just Keeps Going

The Sony WH-CH520 is built around one idea: reliable sound that doesn't need constant charging. A 30mm driver delivers balanced audio across a 20Hz–20,000Hz range, and Bluetooth 5.2 holds a stable connection up to 10 meters for music, calls and everyday listening. At approximately 147 grams, the on-ear design stays light enough for full-day wear without pressing too hard on the ears.

Battery life is the headline feature here — up to 50 hours of continuous playback and up to 200 hours on standby mean the WH-CH520 can go a full week of normal use between charges. When it does need power, USB-C charging brings it back in about 3 hours. Simple onboard volume controls keep the day-to-day experience straightforward, without extra menus or app dependency.
