Sony WH-CH720N lightweight noise-cancelling

Sony WH-CH720N are wireless over-ear headphones with active noise cancellation and 35-hour battery life. The 30 mm drivers deliver a 20 Hz to 20 KHz frequency response and 108 dB sensitivity. Weighing 0.42 kg they use Bluetooth and include a 1.2 m 3.5 mm cable for wired listening.

Comfort-focused listeners wanting all-day wireless

The adjustable ambient sound mode lets you hear surroundings when needed and Precise Voice Pickup technology with beamforming mics handles calls clearly. Multipoint Bluetooth pairs two devices simultaneously. Buyers needing audiophile-grade codecs or fold-flat portability should consider other models.

35-hour battery covers long sessions with ANC on

A full charge provides 35 hours of playback with noise cancelling active. The 325 ohm impedance and 108 dB signal-to-noise ratio support clean output at moderate volumes. Heavy bass enthusiasts or users requiring ultra-low latency gaming modes will find the headroom limited.

Questions about this item

Does the 3.5 mm cable let me use the headphones with a non-Bluetooth device?

Yes, the included 1.2 m cable with a 3.5 mm connector works with any device that has a standard headphone jack.

Will the Bluetooth multipoint feature stay connected to my laptop and phone at the same time?

The headphones can pair with two Bluetooth devices simultaneously so you can switch between them without re-pairing.

How do I confirm the noise cancelling is actually reducing sound after I turn it on?

You should notice an immediate drop in ambient noise such as fans or traffic when the noise cancelling is activated.
