Everyday wireless headphones with 50-hour battery

The Sony WH-CH520 are on-ear Bluetooth headphones built for daily listening and calls. A multipoint connection lets you stay linked to two devices at once, while Swift Pair and Fast Pair make initial setup quick. On-board buttons handle playback, volume and voice-assistant access without reaching for your phone.

Up to 50 hours playback

A full charge delivers up to 50 hours of continuous audio. When the battery runs low, a three-minute top-up via the included USB-C cable adds roughly 1.5 hours of listening time. The lightweight on-ear design keeps the headphones comfortable during long sessions without active cooling or fan noise.

Replaces wired or ageing Bluetooth sets

These headphones upgrade from tethered earbuds or older wireless models that need daily charging. The jump is worth it when you want multipoint convenience, voice-assistant control and a full workweek of battery between charges. Buyers who need active noise cancellation or over-ear isolation should look elsewhere.
