Sony Wh CH720N

The Sony WH-CH720N is Sony's lightest over-ear (circumaural) wireless noise-canceling headphone at just 192 grams, bringing the flagship-derived Integrated Processor V1, Dual Noise Sensor technology, 30 mm drivers with DSEE, 2-device Bluetooth 5.2 Multipoint, and up to 35 hours of ANC battery life to an everyday travel and home-office package.

Integrated Processor V1 and Dual Noise Sensor ANC in a 192 g frame

Upgrading substantially over the previous WH-CH710N, each earcup of the WH-CH720N contains both feedforward and feedback microphones processed in real time by Sony's Integrated Processor V1 to cancel low-frequency bus, train, aircraft, and office air-conditioning noise with minimal processing delay. A newly designed Wind Noise Reduction structure around the exterior microphones minimizes wind turbulence outdoors, while the Sony Sound Connect (Headphones Connect) app offers 20 adjustable steps of Ambient Sound Mode transparency with an optional Voice Focus pass-through and location-aware Adaptive Sound Control.

30 mm dynamic drivers, DSEE upscaling, and 5-band custom EQ

Acoustic output is handled by 30 mm dynamic drivers spanning 7 Hz – 20,000 Hz in wired operation (20 Hz – 20,000 Hz over Bluetooth) and tuned alongside the V1 chip for natural vocal reproduction and clean low-end extension. Sony's Digital Sound Enhancement Engine (DSEE) restores high-frequency detail compressed out of streaming tracks, and users can tailor sound with a 5-band equalizer, Clear Bass slider, and 360 Reality Audio personalization inside the mobile app.

Beamforming calls, Multipoint Bluetooth 5.2, 35h battery, and 3.5 mm jack

For voice calls and video conferencing, beamforming microphones with Precise Voice Pickup Technology isolate speech from ambient background noise. Physical tactile buttons on the earcups control power, ANC/Ambient toggling, playback, and volume. The WH-CH720N runs for up to 35 hours with ANC on (up to 50 hours with ANC off), supports a 3-minute USB-C quick charge for up to 60 minutes of listening, pairs with two devices simultaneously via Bluetooth 5.2 Multipoint (plus Google Fast Pair and Microsoft Swift Pair), and includes a detachable 1.2 m 3.5 mm stereo cable for wired listening both powered on (325 Ω) and powered off (31 Ω).

Bangladesh buyer checklist

Before purchasing the Sony WH-CH720N from any seller in the BiponiBD catalog, confirm the color variant (Black, White, Blue, or Pink), verify that both the 1.2 m 3.5 mm audio cable and USB-C charging cable are inside the box, and check seller warranty terms.
