Sony WH-CH720N Wireless Headphones

All-Day Noise Cancelling Without the Weight

The Sony WH-CH720N brings active noise cancellation to a lightweight, over-ear design built for long days rather than studio sessions. At approximately 192 grams, it stays comfortable through full work shifts, commutes and travel, while a dynamic 30mm driver delivers clear, balanced sound across a 7Hz–20,000Hz frequency range. Adaptive Sound Control reads your activity and surroundings and adjusts noise cancelling and ambient sound automatically, so there's no manual switching between environments.

Bluetooth 5.2 keeps the connection stable up to 10 meters, and Ambient Sound Mode lets outside noise through when situational awareness matters more than isolation. Battery life stretches to 35 hours with noise cancelling on and up to 50 hours with it off, with a full charge taking about 3.5 hours over USB — enough runtime to make daily charging optional rather than routine.
