How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a proven noise-cancelling platform with Sony's Dual Noise Sensor Technology and an Integrated Processor V1, choose Sony WH-CH720N; if you need marathon battery life and the flexibility of wired or wireless listening, choose MLF W7. Both are over ear noise cancelling headphones aimed at very different buyers, and after comparing the specs line by line, the gap between them comes down to tuning versus endurance.
• Sony WH-CH720N – biggest strength: Dual Noise Sensor Technology paired with an Integrated Processor V1, plus a lightweight redesigned headband built to create more ear space.
• Sony WH-CH720N – biggest trade-off: It's a manufacturer-refurbished unit covered by a 90-day limited hardware warranty, so you're trading a longer warranty for the refurbished route.
• MLF W7 – biggest strength: A massive built-in battery rated at up to 40 hours of playback, plus dual-mode wired/wireless listening through a 3.5 mm jack.
• MLF W7 – biggest trade-off: Less detail in the spec sheet overall — a single dynamic driver, touch controls, and app-based noise control with no published processor or ambient-mode detail.
• Who should pick Sony WH-CH720N: Buyers who prioritize noise-cancelling engineering, voice-assistant control, and a light, comfortable fit for work-from-home or movie sessions.
• Who should pick MLF W7: Buyers who want maximum playtime per charge, a beige colorway, and the safety net of a wired connection when the battery runs down.
The WH-CH720N is the more technically ambitious of the two. Sony's Dual Noise Sensor Technology works alongside an Integrated Processor V1, which is the clearest signal in the data sheet that noise cancelling is the headline feature here rather than an afterthought. On top of that, the adjustable Ambient Sound mode offers 20 level settings, so you can dial in exactly how much of the outside world you let through — traffic noise, café chatter, transport announcements — without pulling the headphones off.
The feature set goes beyond audio: beamforming microphones with Precise Voice Pickup Technology for hands-free calls, voice-assistant activation with "OK Google" or Alexa, DSEE upscaling for compressed music files, and automatic volume optimization that learns your behavior and recognizes places you visit often. Connectivity is Bluetooth with a 10-meter range, and there's a 3.5 mm jack for wired listening. Who should skip it? Anyone uncomfortable with a refurbished product and its 90-day limited hardware warranty, or buyers who want the longest possible battery number on paper.
MLF W7: Who It's For
The MLF W7 takes the opposite approach: fewer moving parts, more endurance. The spec sheet lists intelligent active noise cancelling that reduces ambient noise for focused listening, positioned for travel, work, flights, and noisy environments. It's a straightforward ANC implementation — there's no named processor or sensor array in the data, so I'd treat it as capable rather than class-leading.
Where it clearly pulls ahead is battery. The built-in battery is rated at up to 40 hours of average life and recharges in about 2 hours. That's the kind of number that suits long-haul flights, multi-day trips, or anyone who simply resents charging cables. It also runs dual-mode: wireless Bluetooth when you want freedom, or a 3.5 mm wired connection when you don't want to think about charge at all. That wired fallback is a real practical advantage that the Sony also offers, but it pairs especially well here given the endurance focus.
Comfort is addressed with soft padded cushions, an adjustable headband, and a lightweight build meant to minimize fatigue over long sessions. The earcups are over ear in a circular shape, the color is beige, and controls are touch-based with app-based noise control. Audio comes from a dynamic driver. The data sheet also notes CE, RoHS, and FCC certifications for safety. Who should skip it? Buyers who want granular ambient-sound control, a named noise-cancelling processor, or voice-assistant wake words — none of those appear in the MLF W7's specs.
• Best for noise-cancelling engineering → Sony WH-CH720N. Dual Noise Sensor Technology plus the Integrated Processor V1 is the more developed ANC story on paper.
• Best for battery life → MLF W7. Up to 40 hours versus up to 35 hours, with a faster 2-hour recharge.
• Best for fine-tuned ambient awareness → Sony WH-CH720N. The 20-level Ambient Sound mode is the only adjustable ambient system between the two.
• Best for quick top-ups → Sony WH-CH720N. USB Type-C quick charging delivers up to 60 minutes of playback from a 3-minute charge.
• Best for hands-free calls and voice assistants → Sony WH-CH720N. Beamforming mics with Precise Voice Pickup Technology and "OK Google"/Alexa activation.
• Best for a lighter, roomier fit → Sony WH-CH720N. A slimmer headband restructured for more ear space at 6.72 ounces.
• Best for travel simplicity → MLF W7. Dual wired/wireless mode plus long endurance means fewer charging worries on the road.
• Best for warranty peace of mind → MLF W7. The Sony is refurbished with a 90-day limited hardware warranty, while the MLF W7 carries no such refurbished caveat in its listing.
I'd buy the Sony WH-CH720N. In my opinion, the Dual Noise Sensor Technology, Integrated Processor V1, 20-level Ambient Sound mode, quick charging, and voice-pickup microphones make it the more complete over ear noise cancelling headphone for daily commuting, working from home, and movie watching. The MLF W7 wins on raw battery life and the beige finish, and if you fly long haul or hate charging, it's the smarter pick. Just go in knowing the Sony is a refurbished unit with a 90-day limited hardware warranty, and check the current price on Amazon before deciding.
what is the best over ear noise cancelling headphones
There's no single answer, but if noise cancelling quality is your priority, the Sony WH-CH720N has the stronger spec story with its Dual Noise Sensor Technology and Integrated Processor V1. If battery life matters more, the MLF W7's up-to-40-hour rating makes it the better fit. Match the pick to your main use case.
which over ear noise cancelling headphones
Choose Sony WH-CH720N if you want adjustable ambient sound with 20 levels, voice-assistant control, and a lightweight 6.72-ounce build. Choose MLF W7 if you want dual wired/wireless listening, soft padded cushions, and longer playtime per charge. Both are over ear models with active noise cancelling and a 3.5 mm jack.
what are the most comfortable over ear noise cancelling headphones
Comfort is personal, but the data points to the Sony WH-CH720N's slimmer, restructured headband creating more ear space, while the MLF W7 emphasizes an ergonomic design with soft padded cushions and an adjustable headband for pressure-free wear. Neither sheet lists weight for the MLF W7, so the Sony's 6.72 ounces is the only figure to go on.
how to on noise cancelling headphones
Turn ANC on, then adjust it to your environment. The Sony WH-CH720N lets you pick from 20 Ambient Sound levels and optimizes volume automatically based on where you are. The MLF W7 handles noise control through its app with touch controls on the earcup, so you tune it there instead.
