• Sony WHCH720N — biggest strength: The complete, current package — Sony's lightest-ever noise-canceling headband at 192 g, up to 35 hours of battery, Processor V1 noise canceling, DSEE sound enhancement, Precise Voice Pickup calling, multipoint pairing, voice control, and a 3.5mm auxiliary jack so you can keep listening wired when the battery runs out.
• Sony WHCH720N — biggest trade-off: It's the new, sealed retail version, so you're paying for that status rather than chasing the lowest possible entry point into this headphone design.
• Amazon Renewed Sony WH-CH720N/P — biggest strength: The same fundamental Sony headphone — 192 g build, Processor V1 noise canceling, up to 35-hour battery with quick charging, Adaptive Sound Control, Ambient Sound mode, Precise Voice Pickup calling — offered as a Renewed unit, which is where the value case lives.
• Amazon Renewed Sony WH-CH720N/P — biggest trade-off: It's Renewed, not new: Pink only, a 90-day limited warranty instead of a standard retail one, no 3.5mm jack, and Bluetooth 5 rather than 5.2.
• Who each pick is for: Sony WHCH720N suits buyers who want the sealed, fully-featured, wired-capable version and don't want to think about condition; Amazon Renewed Sony WH-CH720N/P suits budget-focused buyers who want the same core listening and noise-canceling experience and accept the trade-offs.
The WH-CH720N is Sony's lightest over-ear wireless noise-canceling headband, and that 192 g figure is the headline. In practice it means a headphone you can leave on through a long work-from-home afternoon, a full commute, or a back-to-back meeting day without the clamping pressure that heavier flagships build up. The nylon carrying case and plastic enclosure keep the whole thing travel-friendly rather than precious.
For connectivity you get Bluetooth 5.2, a 10-meter range, multipoint so you can stay paired to two devices at once, and voice control with Alexa support. There's also a 3.5mm auxiliary jack — that's the detail people forget until their battery dies on a flight and they still want to listen.
Buy it if you want the sealed retail version, you value the wired fallback, you want the newer Bluetooth spec, and you'd rather not spend mental energy on condition or warranty length. Skip it if your only goal is the lowest possible entry into this headphone design and you're comfortable with a Renewed unit.
Amazon Renewed Sony WH-CH720N/P: Who It's For
This is the same Sony headphone architecture, sold through Amazon Renewed. The spec sheet tells the story plainly: 192 g, "Sony's lightest wireless noise canceling headband ever," Dual Noise Sensor technology with the Integrated Processor V1, Adaptive Sound Control, Ambient Sound mode, up to 35-hour battery life, and quick charging that Sony quotes as 3 minutes for up to an hour of playback. Calling relies on Precise Voice Pickup Technology with beamforming mics. If what you want is the WH-CH720N experience — light on the head, competent ANC, long battery — this delivers it.
The differences are real, though, and you should weigh them honestly. This unit is Pink, and the enclosure is listed as metal and recycled plastic rather than the plastic build on the new version. Bluetooth is listed as version 5 rather than 5.2, the impedance figure is listed much higher (324.99 ohm versus 40 ohm), and the frequency range is stated as 20Hz–20,000Hz. There is no headphone jack at all — wireless only. Controls run through the app and voice rather than touch. It ships with a short USB-A to USB-C cable, and the warranty is a 90-day limited warranty rather than a standard retail term. The age range is broader too — adult, kid, and teen.
Buy it if you want the core WH-CH720N formula — light build, Processor V1 noise canceling, long battery, Adaptive Sound Control — and you're comfortable trading the wired jack, the newer Bluetooth version, color choice, and a longer warranty for a Renewed unit. Skip it if you need a 3.5mm jack, you specifically want Black, or a 90-day warranty window feels too short for how you use headphones.
• Best for a sealed, brand-new unit → Sony WHCH720N. It's the retail version with the standard packaging and warranty path.
• Best for lowest entry cost into this design → Amazon Renewed Sony WH-CH720N/P. Renewed is the whole point here; check the current price on Amazon before deciding, since that gap is what the decision hinges on.
• Best for wired listening → Sony WHCH720N. It has a 3.5mm auxiliary jack; the Renewed unit has no jack at all.
• Best for the newest Bluetooth spec → Sony WHCH720N. Bluetooth 5.2 versus 5 on the Renewed listing.
• Best for color choice → Sony WHCH720N. Black, versus Pink only on the Renewed unit.
• Best for warranty length → Sony WHCH720N. A standard retail warranty versus a 90-day limited warranty on the Renewed unit.
• Best for battery life → tie. Both are rated up to 35 hours, and both support quick charging.
• Best for noise canceling and sound tech → effectively a tie. Both list Dual Noise Sensor technology, the Integrated Processor V1, and DSEE-driven balanced tuning. The core listening and ANC experience is the same family of hardware.
In my opinion, if you can stretch to it, buy the Sony WHCH720N. The 3.5mm jack, Bluetooth 5.2, Black colorway, multipoint, and a normal warranty term make it the version I'd want to live with for years — those are exactly the small things you miss once they're gone. The Amazon Renewed Sony WH-CH720N/P is the smarter pick only if the goal is the lowest-cost way into this headphone's core experience and you're genuinely fine with Pink, no wired option, and a 90-day warranty. Decide which of those two buyers you are, and the choice makes itself.
FAQ
Largely, yes. Both list the same 192 g weight, Dual Noise Sensor technology with the Integrated Processor V1, up to 35-hour battery life, quick charging, Adaptive Sound Control, and Precise Voice Pickup calling. The differences are in the details: the Renewed unit is Pink, lists Bluetooth 5 instead of 5.2, has no 3.5mm jack, and carries a 90-day limited warranty.
Yes — it includes a 3.5mm auxiliary jack, so you can plug in and keep listening without Bluetooth. The Amazon Renewed Sony WH-CH720N/P lists no headphone jack, so it's wireless-only.
Both are rated up to 35 hours, and both support quick charging. The Renewed listing specifies 3 minutes of charging for up to an hour of playback; battery charge time is listed at about 3.5 hours. On paper there's no meaningful advantage either way.
That depends entirely on how much you value the trade-offs. If you want Black, a 3.5mm jack, Bluetooth 5.2, and a standard warranty, the new Sony WHCH720N is the better fit. If you only want the core Sony noise-canceling experience for as little as possible and Pink is fine, the Renewed unit makes sense — check the current price on Amazon to see how big the gap actually is.
