Easy hands-free calling

Conversation flows freely with easy hands-free calling, thanks to the built-in microphone.2 No need to even take your phone from your pocket.

Your sound, just how you like it

Tailor sound to your personal preference by choosing from a variety of pre-sets to match sound quality with the genre of music you're listening to. Or create and save your own pre-sets using the EQ Custom feature on the Sony│Headphones Connect app.

Make your music more natural

When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. Our Digital Sound Enhancement Engine (DSEE) faithfully restores these to produce high-quality sound that's closer to the original recording.

Select the color that suits your style

With a choice of black, blue, white or beige - you can choose whichever suits you best and enjoy comfortable texture and quality.

Take your music wherever you go

The compact, lightweight design and swivel earcups make the headphones the perfect companion for all of your travels.

Aiming to achieve a zero environmental footprint

Inspired by the beauty of the world, Sony is doing its part to help preserve the Earth, while still allowing creators to produce even more beautiful and creative imagery. With a goal of achieving a zero environmental footprint across the entire Sony Group by the year 2050, we are accelerating numerous green initiatives.

Sustainability in mind

The WH-CH520 headphones are designed for both comfort and environmental consciousness. The headphones use recycled plastic materials, and the packaging uses no plastic.
