WH-CH730N Wireless Noise-Cancelling Headphones
Sony WH-CH730N wireless headphones deliver dual noise sensor technology in a foldable package, adjustable sound modes, and a 207 g lightweight design with comfortable, wrinkle-free, ear cushions.
Shut out the world. Just you and your music
Twin mics in each earcup accurately isolate ambient noise from your music. This Dual Noise Sensor technology can effectively block surrounding distractions, or offers Ambient Sound Modes with 20 levels of adaptive control, allowing you to catch important announcements and keeping you safe in busy cityscapes. It can even detect your habits and automatically tailor the adjustments for you.

Wind Noise Reduction Structure
The WH-CH730N features a redesigned microphone surrounding structure and optimized mic positioning. This effectively reduces wind noise during calls and music playback in both Noise Cancelling and Ambient Sound Modes.
Natural and adjustable Ambient Sound Mode
Our upgraded Ambient Sound Mode now delivers more natural ambient noise passthrough, and especially human voices. Adjust ambient sound across 20 levels in the Sony | Sound Connect app or activate Voice Passthrough to reduce background noise while allow you to hear speech with ease.
Adjusts to the world around you
Adaptive Sound Control senses where you are and what you're doing, then uses AI to change ambient sound settings for the ideal listening experience. Over time, it can learn your behaviour, recognize locations you visit often and tailor the sound to suit your location.

Tailor your ideal sound with balanced tuning and versatile EQ
Rich, well-balanced audio, refined with 1000X-series acoustic know-how. DSEE™ restores lost high frequencies from compressed files and an upgraded 10-band EQ alongside dedicated Game EQ presets lets you freely tweak output to suit your unique taste. Immersive 360 Reality Audio further elevates your listening experience.
Keeping your authentic sound
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.
Tune it your way
Every day has its own rhythm. Use the 10-band equalizer in the Sony | Sound Connect app to tune it: lift the vocals, deepen the bass or save your signature mix for when the mood hits. For gamers, our Game EQ, developed with INZONE expertise, further enhances sound clarity for FPS play.
