Designed for everyday listening, work, travel and entertainment, these headphones combine Sony's noise-cancelling technology with a lightweight construction and convenient smart features.

Powerful Noise Cancellation for Everyday Listening
One of the biggest attractions of the Sony WH-CH720N headphones is their active noise cancellation system.
Sony uses Dual Noise Sensor technology together with the Integrated Processor V1 to capture surrounding sound and process it for noise cancellation. This can be particularly useful when travelling, working in a busy environment, studying or simply listening to music at home.
The headphones also provide an Ambient Sound mode, allowing you to remain more aware of your surroundings without completely removing the headphones.
For users who frequently move between quiet rooms, offices, streets and public transport, having both Noise Cancelling and Ambient Sound modes makes the WH-CH720N considerably more versatile than basic Bluetooth headphones.
Sony Integrated Processor V1 for Better Sound and Noise Control
The Sony WH-CH720N incorporates Sony's Integrated Processor V1, the same processor family Sony uses in its noise-cancelling headphone lineup.
The processor works alongside the Dual Noise Sensor system for noise cancellation while also supporting Sony's sound-processing technologies. Sony says the combination helps deliver natural vocals, clear sound and balanced tuning.
This makes the headphones suitable for a wide range of content, including:
Bollywood and international music
Podcasts
YouTube videos
Movies and web series
Online classes
Audiobooks
Video calls
General everyday listening
DSEE Technology for Enhanced Audio
Another useful feature is Sony's Digital Sound Enhancement Engine (DSEE).
Compressed digital music can lose some high-frequency information during compression. Sony's DSEE technology is designed to restore some of the high-frequency sound and fine fade-out details that can be lost during compression.
For everyday streaming, this can help provide a more enjoyable listening experience, particularly for users who want more detail without moving into a premium audiophile headphone category.
30 mm Dynamic Drivers
The WH-CH720N uses 30 mm dynamic driver units. Sony specifies a frequency response of 7 Hz–20,000 Hz for active operation and the same range for the wired passive specification under its stated measurement conditions.
The 30 mm drivers are designed to provide a balanced presentation suitable for everyday entertainment rather than focusing on one particular type of music.
Whether you enjoy vocals, pop, electronic music, movies or podcasts, the WH-CH720N is designed as an all-purpose wireless headphone.
Up to 35 Hours of Battery Life
Battery life is another major reason to consider the Sony WH-CH720N.
Sony rates the headphones for:
Up to 35 hours with Noise Cancelling ON
and
Up to 50 hours with Noise Cancelling OFF.
That gives the WH-CH720N enough endurance for extended listening sessions without requiring frequent charging.
Battery performance can vary depending on settings, codec, usage conditions and other factors, so the advertised maximum should be viewed as a manufacturer-rated figure rather than a guarantee for every usage scenario.
The headphones take approximately 3.5 hours to fully charge, while Sony also specifies quick-charging capability. Its support documentation states that around 60 minutes of music playback can be obtained from approximately three minutes of charging under specified conditions.
Multipoint Connectivity: Connect Two Devices
For people who use both a smartphone and a laptop, Bluetooth Multipoint is one of the most useful features of the Sony WH-CH720N.
The headphones can be paired with two Bluetooth devices simultaneously, making it easier to move between your computer and smartphone. For example, you can listen to audio from your laptop while remaining connected to your phone for calls.
This feature is particularly useful for:
Office workers
Remote workers
Students
People attending online meetings
Users who regularly switch between phone and laptop
Instead of repeatedly disconnecting and reconnecting your headphones, Multipoint provides a more convenient connected-device experience.
Clearer Calls with Precise Voice Pickup
The Sony WH-CH720N is not just designed for music. It also includes technology intended to improve voice-call quality.
Sony incorporates Precise Voice Pickup technology, a beamforming microphone and a Wind Noise Reduction Structure to help provide clearer and more natural conversations.
This makes the headphones suitable for:
Zoom meetings
Google Meet
Microsoft Teams
Phone calls
Online classes
Work-from-home communication
As with any Bluetooth headset, actual call quality can depend on the connected device, software and surrounding environment.
Lightweight 192 g Design
Comfort can make a significant difference when wearing headphones for several hours.
The Sony WH-CH720N weighs approximately 192 grams, making it notably lightweight for an over-ear noise-cancelling headphone. Sony specifically positions the model around extended comfort and all-day listening.
The lightweight construction makes the WH-CH720N a particularly interesting choice for commuters, students, office users and frequent travellers who don't want a heavy headphone pressing down on their head during long sessions.
Bluetooth 5.2 Connectivity
The WH-CH720N uses Bluetooth 5.2 and supports the SBC and AAC audio codecs. Sony specifies a maximum communication range of approximately 10 metres under suitable conditions.
Bluetooth performance can vary depending on walls, interference, connected devices and the surrounding environment.
The headphones also support standard Bluetooth profiles including A2DP, AVRCP, HFP and HSP.
Sony | Sound Connect App
The WH-CH720N can be used with Sony's companion Sony | Sound Connect app, providing additional control over supported headphone functions.
Sony's current product information indicates that the app can be used to adjust ambient sound settings, including multiple levels of ambient sound control.
The app can therefore make the headphones more adaptable to different listening environments.
Wired Listening Option
Although the Sony WH-CH720N is primarily a wireless Bluetooth headphone, it also includes a stereo mini jack and detachable connection cable.
Sony lists a cable length of approximately 1.2 metres, giving users the option of wired listening when required.
This can be useful when Bluetooth isn't available or when you simply prefer a wired connection.

Sony WH-CH720N vs Regular Bluetooth Headphones
A basic Bluetooth headphone may provide wireless music playback, but the WH-CH720N offers a much broader feature set.
With Sony's model, you get active noise cancellation, Ambient Sound mode, DSEE, Multipoint connectivity, advanced microphone technology and long battery life in addition to Bluetooth audio.
That makes the WH-CH720N particularly attractive for people who want one headphone for music, travel, work, calls and entertainment instead of purchasing separate devices for different situations.

The Noise Cancelling system can help reduce surrounding distractions, while the approximately 192 g weight makes it comfortable to carry and wear for extended periods. The battery can provide up to 35 hours of music playback with Noise Cancelling enabled under Sony's specified conditions.
For long flights, train journeys, bus rides or daily commuting, these features can make a noticeable difference in convenience.

The answer is also yes.
Multipoint connectivity is particularly useful for people who work across a laptop and smartphone. Sony's Precise Voice Pickup technology, beamforming microphone and Wind Noise Reduction Structure are designed to improve call clarity.
For remote workers, the ability to remain connected to two devices can reduce the inconvenience of constantly changing Bluetooth connections.
Is Sony WH-CH720N Worth Buying?
The Sony WH-CH720N makes a strong case for itself if your priorities are active noise cancellation, lightweight comfort, long battery life, clear calls and Multipoint Bluetooth connectivity.
