Sony WH-CH720N Blue Wireless Noise-Cancelling Headphone

Lightest Wireless Noise-Cancelling Headband

Sony's WH-CH720N in blue is the brand's lightest wireless noise-cancelling headband to date, weighing 0.42 units. The Integrated Processor V1 drives the active noise cancellation while Adaptive Sound Control adjusts the level to match surroundings. It suits listeners who want all-day comfort with effective isolation for commuting or office work. Buyers who need higher clamping force for vigorous exercise will find the lightweight build less secure.

Thermals Noise and Power Draw

Passive operation produces no fan noise or measurable heat during listening sessions. The rechargeable battery delivers up to 35 hours with noise cancelling active and 40 hours with it off. A three-minute quick charge adds roughly one hour of playback, keeping downtime minimal for daily use. The 325-ohm impedance and 108 dB sensitivity allow efficient drive from portable sources without extra amplification.

Build Quality Connectors and Daily Use

The closed, over-ear design uses a 30 mm dynamic driver and a gold-plated L-shaped 3.5 mm stereo mini plug on a 1.2 m single-sided cord for wired backup. Multipoint Bluetooth pairing lets the headphones stay connected to two devices simultaneously, while Google Fast Pair and the Headphones Connect app streamline initial setup. Precise voice pickup and hands-free calling support voice assistants without removing the headset. Users who require a balanced or proprietary connector must look elsewhere.
