Wireless on-ear headphones with 50-hour battery

Sony WH-CH520 Wireless On-Ear Headphones in Pink deliver up to 50 hours of wireless listening on a single charge. Quick charging via USB Type-C provides 90 minutes of playback after just 3 minutes. The lightweight 0.42-gram frame features soft ear pads and an adjustable headband for extended comfort. Multipoint Bluetooth lets you stay connected to two devices simultaneously.

Suited for daily commuters and multi-device users

Listeners who value long battery life, easy device switching and a light on-ear fit will appreciate this model. Built-in microphone and on-board controls support hands-free calls and voice assistant access. The Sony Headphones Connect app adds EQ customisation and DSEE upscaling for compressed tracks. Buyers who need active noise cancellation or over-ear isolation should consider other options.

50-hour battery with 3-minute quick charge

The single specification that decides fit is the 50-hour operating time combined with 90 minutes of playback from a 3-minute charge. This endurance covers multi-day trips without carrying a cable. If your routine demands longer unplugged sessions or you prefer a wired connection for zero-latency use, this headset does not meet that requirement.

Questions about this item

How much does the pink WH-CH520 weigh, and will it feel heavy on my ears?

At 0.42 grams the on-ear design is extremely light, with soft ear pads and an adjustable headband cushion for all-day comfort.

What is the first step to pair these headphones with my phone, and what do people often miss?

Enable Bluetooth on your device, then hold the power button until the indicator flashes; the step many miss is opening the Sony Headphones Connect app to finish pairing and enable multipoint.

The battery is sealed — what happens when it no longer holds a 50-hour charge?

The lithium-ion battery is not user-replaceable; when capacity drops you would need to contact a Sony authorised service centre for a battery swap.
