• Sony WH-CH720N — biggest strength: Dual Noise Sensor Technology with the Integrated Processor V1, a slim lightweight headband rebuilt for ear space, 20-level Ambient Sound control, up to 35 hours of battery, and a 3.5 mm jack so you can keep listening wired.
• Sony WH-CH720N — biggest trade-off: It's the heavier of the two on paper, it arrives in black only, and it relies on voice control rather than an app for its smart features.
• Amazon Renewed Sony WH-CH720N/P — biggest strength: The same noise cancelling core (Dual Noise Sensor + Integrated Processor V1) in Sony's lightest over-ear wireless noise cancelling headband, listed at just 192g, in a pink finish with app and voice control.
• Amazon Renewed Sony WH-CH720N/P — biggest trade-off: No headphone jack at all, so wired listening isn't an option, and its listed weight figure is dramatically lower than the other listing's.
• Who each pick is for: Pick the Sony WH-CH720N if you want flexibility (wired or wireless) and a neutral black finish; pick the Amazon Renewed Sony WH-CH720N/P if weight and app control matter most to you.
The Sony WH-CH720N is built around Sony's Dual Noise Sensor Technology paired with the Integrated Processor V1. In plain terms, that's the hardware that drives the active noise cancelling, and it's the same generation of processing Sony uses across this headphone family. The headband has been slimmed down and restructured to open up more space around the ears, which is the kind of change that matters more than it sounds like on a spec sheet — over-ear comfort usually comes down to how the band distributes weight and how much room your ears get inside the cups.
Battery is a genuine strength: up to 35 hours of playback, plus USB Type-C quick charging that gives you up to 60 minutes of playback from a 3-minute charge. If you're the sort of person who forgets to plug things in, that quick-charge figure is the one to remember. Ambient Sound mode gives you 20 level settings, so you can dial in how much of the outside world you let through — useful for hearing transport announcements or a café conversation without pulling the headphones off.
It's also the more flexible of the two for connectivity. You get Bluetooth 5 for wireless, a 10-metre range, and a 3.5 mm jack for wired listening. There's also DSEE to improve compressed audio files, Precise Voice Pickup Technology with beamforming microphones for calls, and voice assistant activation ("OK Google" or Alexa). Controls are voice-based for the assistant side.
Who should buy it: Anyone who wants noise cancelling, long battery and the safety net of a wired connection — flights, trains, desks, and long work-from-home sessions. Who should skip it: If you specifically want the lightest possible over-ear build or you prefer app-based control, the other listing fits better. It's listed in black only, and it's the heavier option here.
This listing is the same Sony WH-CH720N platform, sold as a renewed unit under the Amazon Renewed brand. The headline claim is weight: it's described as Sony's lightest wireless noise cancelling headband ever, at just 192g. That number is worth pausing on, because it's far below the weight stated on the other listing. Whether that reflects a different measurement method, a different configuration, or simply a difference in how each listing was written up, I can't say from the data — but if light weight is your priority, this is the listing that puts that number front and centre.
Feature-wise, it carries the same core: Dual Noise Sensor Technology with the Integrated Processor V1, up to 35-hour battery life, quick charging (3 minutes for up to 1 hour of playback) and a USB Type-C cable in the box. You also get Adaptive Sound Control alongside the adjustable Ambient Sound mode, which tailors sound to your surroundings. DSEE is on board for cleaner streaming audio, and Precise Voice Pickup Technology handles hands-free calls through beamforming microphones.
The control story is different, though. This one is controlled by app and voice rather than voice alone — the app route gives you a more visual way to manage settings like ambient sound levels and adaptive behaviour. The enclosure mixes metal and recycled plastic, and the finish here is pink rather than black. Note one clear omission: there's no headphone jack. This is a wireless-only headphone.
Who should buy it: Buyers who want minimal weight on their head for long stretches, who like managing settings in an app, and who don't care about wired listening. Who should skip it: If you ever plug into a laptop, in-flight entertainment system or audio interface, this one can't do it.
• Best for wired flexibility → Sony WH-CH720N. It has a 3.5 mm jack; the /P model does not.
• Best for lowest listed weight → Amazon Renewed Sony WH-CH720N/P. Its listing states 192g, the lightest over-ear noise cancelling figure between the two.
• Best for battery confidence → a tie. Both list up to 35 hours, with quick charging on both.
• Best for app-based control → Amazon Renewed Sony WH-CH720N/P. It lists app and voice control; the other lists voice control.
• Best for a neutral, understated finish → Sony WH-CH720N. It's listed in black; the /P is listed in pink.
• Best for hands-free calling → a tie. Both use Precise Voice Pickup Technology with beamforming microphones.
• Best for streaming audio quality → a tie. Both include DSEE and the Integrated Processor V1.
• Best for buyers who want the widest connection options → Sony WH-CH720N. Bluetooth plus a wired jack covers more situations.
One thing to keep in mind on both: they're renewed products, each carrying a 90-day limited hardware warranty, and each listing describes the unit as manufacturer refurbished with limited or no wear and all original accessories. That matters for how you think about risk — the coverage window is shorter than a new-unit warranty, so buy with that in mind.
I'd buy the Sony WH-CH720N. In my opinion, the 3.5 mm jack is the deciding feature: it turns a wireless headphone into something you can still use on a plane seatback screen, a desktop DAC or a dying-battery day, and no weight figure makes up for losing that. The black finish is also easier to live with as an everyday pair. The Amazon Renewed Sony WH-CH720N/P is the better pick only if you're certain you'll never want a cable and you want the lightest listed build with app control. If price is the thing you're weighing, check the current price on Amazon for both before you commit — that's the one variable I can't compare for you here.
how to on noise cancelling headphones
Turn on active noise cancelling, put the headphones on, and let the processor handle steady low-frequency noise like engine drone or air conditioning. Both headphones here use Dual Noise Sensor Technology with Sony's Integrated Processor V1. Use Ambient Sound mode — 20 levels on the WH-CH720N, adjustable on the /P — when you need to hear announcements or conversation.
what is the best over ear noise cancelling headphones
There's no single answer, because "best" depends on your priorities. If you want wired flexibility plus noise cancelling and up to 35 hours of battery, the Sony WH-CH720N is the stronger fit. If you want the lightest listed build and app-based control in a wireless-only design, the Amazon Renewed Sony WH-CH720N/P makes more sense for you.
which over ear noise cancelling headphones
Choose based on how you listen. Need a 3.5 mm jack and a black finish? Take the Sony WH-CH720N. Want app control, a pink finish and a wireless-only headphone listed at 192g? Take the Amazon Renewed Sony WH-CH720N/P. Both share the same noise cancelling processing, quick charging and 90-day limited warranty.
what are the most comfortable over ear noise cancelling headphones
Comfort is personal, but the specs point in two directions. The Sony WH-CH720N uses a slimmer, lightweight headband restructured to create more space around the ears. The Amazon Renewed Sony WH-CH720N/P leans on its 192g listed weight and a lightweight design. If ear room matters most, look at the headband design; if sheer lightness matters most, look at the weight figure.
