The Sony WH-CH520 BLACK headphones feature Bluetooth 5.2 for a stable connection and minimal latency. Multipoint connectivity lets you pair them with two devices simultaneously, making it easy to switch between incoming calls or media sources.
Battery Life
Up to 50 hours of playback and 40 hours of talk time. If the battery runs low, a quick 3-minute charge provides an additional 1.5 hours of playback—perfect for those constantly on the move who want music at hand.
Sound Quality
DSEE (Digital Sound Enhancement Engine) technology restores details lost during compression for richer, more dynamic audio. They support AAC and SBC codecs for high-quality sound from compatible devices. The Headphones Connect app’s equalizer allows you to tailor the sound to your personal preferences.
Controls
Simple buttons let you skip tracks, adjust volume, and answer calls with one press. Voice control via Google Assistant or Siri enables hands-free operation without taking out your phone.
