Overview

The Sony WH-CH520 wireless headphones are designed for listeners who prioritize comfort, convenience, and marathon battery life. With up to 50 hours of playback on a single charge, these on-ear headphones can easily last through a full work week without needing to be plugged in. The lightweight build keeps them comfortable during extended listening sessions, whether you're commuting, working at a desk, or relaxing at home. Bluetooth connectivity with Fast Pair (Android) and Swift Pair (Windows) support means you can get connected in seconds without digging through settings menus.
