Sony WH-CH720N Wireless Noise Cancelling Headphones
The Sony WH-CH720N Wireless Noise Cancelling Headphones offer a refined listening experience with lightweight comfort, advanced noise-cancelling technology, and long-lasting battery life. Engineered with Dual Noise Sensor technology and Sony’s Integrated Processor V1—borrowed from their premium 1000X series—these headphones deliver effective active noise cancellation to reduce ambient sounds, making them ideal for commuting, work, or focused listening in noisy environments.
Equipped with 30mm dynamic drivers, the WH-CH720N provides balanced, detailed sound with support from Sony’s Digital Sound Enhancement Engine (DSEE), which enhances compressed music files for richer audio quality. Whether you're enjoying music, podcasts, or calls, the sound remains clear and immersive.
Comfort is another highlight of the CH720N. Weighing just 192 grams, they are among the lightest over-ear noise cancelling headphones in Sony’s lineup. The adjustable headband, soft ear cushions, and ergonomic design make them comfortable for all-day wear. Though not foldable, their slim profile makes them easy to pack in a bag or case.
With Bluetooth 5.2 connectivity, the headphones support multi-point pairing, allowing you to connect to two devices at once—making it easy to switch between listening to music on your tablet and taking a call on your phone. Physical buttons on the earcups provide intuitive control over volume, playback, and noise cancellation modes, while voice assistant support adds hands-free convenience.
Battery life is a major strength, offering up to 35 hours of playback with noise cancellation on, or up to 50 hours with it off. A quick 3-minute charge gives up to 1 hour of playback, keeping you powered up on the go. Audio settings and noise control features can be customized via the Sony Headphones Connect app.
