The Sony WH-CH520 Wireless Bluetooth Headphones are lightweight yet powerful on-ear wireless headphones designed for everyday listening with comfort and convenience in mind. They offer an impressive battery life of up to ~50 hours on a single charge, so you can enjoy music, podcasts, and calls all day long without frequent charging, and quick charging provides extra playtime with just a short top-up. Featuring Bluetooth 5.2 connectivity, these headphones support multipoint pairing to stay connected to two devices at once, and the built-in microphone enables clear hands-free calls and voice assistant access. Sony’s DSEE audio enhancement helps restore detail in compressed music files, while the EQ Custom feature via the Sony Headphones Connect app lets you fine-tune your sound to match your preferences. Built with soft ear cushions, an adjustable headband, and a lightweight design (~147 g), these headphones are comfortable for long listening sessions and easy to carry around for travel, work, or daily use.
