Superb sound for every song
Enjoy natural vocals, crystal clear sound and balanced tuning thanks to the Integrated Processor V1 and Digital Sound Enhancement Engine (DSEE), producing a high-quality sound exactly as the artists intended.

Experience a better-balanced sound
Our Integrated Processor V1 provides an authentic listening experience by reproducing the detail in your music with minimal distortion. The sound tuning is intentionally designed to be well-balanced from low to high frequencies, with natural and clear vocals.

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.

Your sound, just how you like it
The EQ Custom feature on the Sony | Sound Connect app tailors sound to your personal preference. Choose from a variety of presets to match sound quality with the genre of music you're listening to. Or create and save your own presets.

Crystal clear conversations
With Precise Voice Pickup Technology, Wind Noise Reduction Structure, and beamforming mics to pick up your voice, you will enjoy clearer calls and better conversations.

Beamforming microphones for clearer calls
Precise Voice Pickup Technology uses beamforming microphones to allow WH-CH720N headphones to pick up voices clearly and accurately for hands-free calls.
