How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a black over-ear noise-canceling headphone for laptop work with a straightforward wired fallback, choose Sony WH-CH720NB; if you need the same core Sony noise-canceling platform in a pink finish with smarter ambient features and modern Bluetooth 5.2, choose Sony WH-CH720N.
• Sony WH-CH720NB — biggest strength: Matte black finish with a connection cable in the box, so you can fall back to wired listening for laptop use. Biggest trade-off: Bluetooth 5 (not 5.2), and the bundled accessories push it toward a basic setup rather than a smart one.
• Sony WH-CH720N — biggest strength: Bluetooth 5.2, Adaptive Sound Control, adjustable Ambient Sound mode (20 levels), and Precise Voice Pickup Technology for calls. Biggest trade-off: Ships in Pink only, and its included cable is a short USB-C charging cable rather than a wired audio cable.
• The core is nearly identical. Both weigh 192g, both use the Integrated Processor V1, Dual Noise Sensor technology, DSEE, 325 ohm impedance, 108 dB sensitivity, a dynamic driver with a 20Hz–20,000Hz range, and up to 35 hours of battery.
• Pick Sony WH-CH720NB if you want a neutral matte black look and a wired connection option for laptop audio.
• Pick Sony WH-CH720N if you want smarter sound adaptation, better call pickup, and you don't mind pink.
The WH-CH720NB is the matte black variant of Sony's lightweight noise-canceling over-ear platform. Its biggest practical differentiator in the data sheet is what's in the box: a connection cable alongside the USB cable. That matters for laptop users. Bluetooth is great, but a wired fallback is genuinely useful for video calls, latency-sensitive work, or when you simply don't want to manage a Bluetooth pairing on a machine that's already juggling peripherals.
The spec sheet lists compatibility with cellphones, tablets, and laptops, which is exactly the use case this headphone is built around. At 192g it's light enough to wear through a long work session, and the ergonomic over-ear design with rounded earpads is meant for exactly that. The Integrated Processor V1 and Dual Noise Sensor technology handle active noise cancellation, and DSEE works on compressed audio to push it closer to the original recording. Frequency response runs 20Hz to 20,000Hz with 325 ohm impedance and 108 dB sensitivity.
Battery is listed at up to 35 hours with quick charge, so a full workweek of on-and-off listening is realistic. Control is via touch and voice, which sounds modern but does mean you're relying on taps and voice commands rather than physical buttons.
Sony WH-CH720N: Who It's For
The WH-CH720N is the pink version of the same headphone family, and it's marketed as Sony's lightest wireless noise-canceling headband design at 192g — the same weight as the NB. Where it pulls ahead is in the software and connectivity story: Bluetooth 5.2, Adaptive Sound Control, an adjustable Ambient Sound mode with 20 levels, and Precise Voice Pickup Technology using beamforming microphones for hands-free calls.
That's a meaningful set of additions for anyone doing a lot of calling from a laptop. Beamforming mics focus on your voice rather than the room, and the ambient modes let you dial in how much of your surroundings you want to hear — useful in an office, a café, or a shared workspace. Multipoint connection lets the headphones sit on two Bluetooth devices at once, so you can switch between a laptop and a phone without re-pairing. There's also voice assistant support for "OK Google" or Alexa.
The headband was restructured to give the ears more space, and the enclosure uses metal and recycled plastic. Battery is up to 35 hours, with a quick charge that gives roughly an hour of playback from about three minutes of charging. Charging time is listed at about 3.5 hours, and the included cable is a short USB-C to USB-A charging cable. Note the control method here is push button rather than touch, which some people strongly prefer for calls.
Buy it if: you take a lot of calls, want adaptive ambient sound, and like the pink colorway. Skip it if: you want a black finish or a wired audio cable in the box.
Side-by-Side: Which Should You Choose?
• Best for laptop work with a wired fallback → Sony WH-CH720NB (connection cable included).
• Best for smart ambient control → Sony WH-CH720N (20-level Ambient Sound mode plus Adaptive Sound Control).
• Best for switching between laptop and phone → Sony WH-CH720N (Multipoint Connection, Bluetooth 5.2).
• Best for a low-key, neutral look → Sony WH-CH720NB (Matte Black).
• Best for physical button control → Sony WH-CH720N (push button rather than touch).
• Best for identical comfort and battery → a tie (both 192g, both up to 35 hours).
• Best for identical sound hardware → a tie (both use the V1 processor, Dual Noise Sensor, DSEE, 325 ohm, 108 dB).
If you're a gamer hunting for the best gaming headphones for laptop use, neither of these is a purpose-built gaming headset — they're Bluetooth noise-cancelers. They'll handle casual game audio and voice chat fine over Bluetooth, but if low latency matters to you, the NB's wired connection is the more practical option of the two. Similarly, if you're comparing against earphones for laptop use, the over-ear form factor here is a different experience entirely: more isolation and comfort for long sessions, less portability.
There's also a niche of shoppers looking at volume limiting neckband headphones for laptop listening. That's a different category — this pair is over-ear with active noise cancellation, not a neckband, and neither is advertised as volume-limiting. Worth knowing so you don't buy the wrong shape.
In my opinion, the Sony WH-CH720N is the better buy for most people, and it's the one I'd pick. The smarter ambient modes, beamforming call mics, Bluetooth 5.2, multipoint pairing, and push-button controls are all things you'll actually use during laptop work — especially calls. The pink finish is the only real catch, and if that's a dealbreaker, the WH-CH720NB gives you the same core sound and comfort in matte black with a wired cable in the box. For a laptop-first buyer who takes calls, I recommend the WH-CH720N.
They share the same core platform — 192g, Integrated Processor V1, Dual Noise Sensor, DSEE, 325 ohm, 108 dB, 20Hz–20,000Hz, and up to 35 hours of battery. The differences are the colorway, Bluetooth version (5 vs 5.2), control type (touch vs push button), bundled cable, and the smart ambient and call features on the N.
The Sony WH-CH720N. It adds Precise Voice Pickup Technology with beamforming microphones and a "Focus on Voice" chat mode, which are designed specifically for clear hands-free calling.
The data sheet for this listing shows Pink only. If you want matte black, the WH-CH720NB is the version to look at.
