Sony WH-CH720N

Sony WH-CH720N – Product Overview

The Sony WH-CH720N are lightweight mid-range wireless over-ear headphones from Sony Corporation designed to bring Active Noise Cancellation (ANC), long battery life, and Sony sound quality at a more affordable price than the WH-1000XM series.

They are basically a “budget-friendly Sony ANC headset” for everyday use.

Audio Performance

The WH-CH720N deliver clean and balanced sound:

• 30mm dynamic drivers
• Clear vocals with light bass emphasis
• DSEE audio upscaling (improves compressed audio)
• Custom EQ via Sony Headphones Connect app
• Good clarity for music, calls, and movies

Sound is balanced and slightly bright, less bass-heavy than XM4.

Noise Cancellation (ANC)

• Dual Noise Sensor technology (similar concept to XM series)
• Active Noise Cancellation (ANC)
• Ambient Sound / Transparency mode
• Adaptive Sound Control (location-based adjustment)

ANC is good for the price, especially for office noise, fans, and travel, but not as strong as WH-1000XM4 or premium Bose models.

Design & Comfort

• Ultra-lightweight over-ear design (~192g)
• Plastic build for reduced weight

One of the lightest Sony over-ear headphones ever made.

Battery Life

• Up to ~35 hours (ANC ON)
• Up to ~50 hours (ANC OFF)

• USB-C charging

Battery life is excellent and slightly better than XM4 on paper.

Smart Features
