• Sony WH-CH720NL — biggest strength: The Integrated Processor V1, DSEE upscaling, 360 Reality Audio support, and 20-level ambient sound adjustment via the Sony app make this the more sophisticated listening tool of the two.
• Sony WH-CH720NL — biggest trade-off: Battery life is rated up to 35 hours with noise cancelling on, and there's no wired fallback listed — so it's a Bluetooth-first product.
• TECKNET Noise Cancelling Headphones — biggest strength: Up to 70 hours in standard mode (45 with ANC), plus a 3.5 mm jack for wired listening when you want it.
• TECKNET Noise Cancelling Headphones — biggest trade-off: The audio story is simpler — a 40 mm driver and ANC rated at 95% noise reduction, with no app EQ or codec/processor features listed.
• Who each is for: Sony for listeners who care about sound tuning and smart app features; TECKNET for commuters, travelers, and office users who want endurance and flexibility.
The Sony WH-CH720NL is the more "engineered" of these two headphones. The spec sheet leans heavily on processing: an Integrated Processor V1, Digital Sound Enhancement Engine (DSEE) to pull compressed files closer to the original recording, and 360 Reality Audio certification that you can optimize by analyzing your ear shape in the Sony | Headphones Connect app. In practice, that means this is a headphone for someone who wants to shape how music sounds rather than just accept a default tuning.
Noise cancelling here is digital and adjustable. Dual Noise Sensor technology paired with the Processor V1 lets you move ambient sound across 20 different levels in the app — so you can dial in how much of the outside world you let through while you're on the move. Add Multipoint Connection for two Bluetooth devices at once, Swift Pair and Fast Pair for quick setup, voice control, and Precise Voice Pickup Technology with beamforming mics and a wind noise reduction structure, and you get a headphone built for calls as much as for music.
Buy it if you want app-based EQ, ambient sound control, multipoint pairing, and a lighter build for all-day wear. Skip it if you need wired listening, the longest possible battery number, or a foldable travel shape.
TECKNET Noise Cancelling Headphones: Who It's For
The TECKNET Noise Cancelling Headphones are built around endurance and versatility. The headline number is 70 hours of playtime in standard mode, dropping to 45 hours with ANC active — and a 10-minute charge over USB-C gets you roughly 4 hours of listening. For someone who resents charging a headphone every couple of days, that's the whole pitch right there.
The noise cancelling is Active Noise Cancelling with a claimed 95% noise reduction, and TECKNET notes that ANC must be actively switched on via the button — a detail worth knowing if you ever think the feature isn't working. Audio comes from 40 mm dynamic drivers, tuned for deep bass and crisp highs. There's no app or EQ layer mentioned, so this is a set-and-go sound signature rather than a tunable one.
Where TECKNET pulls ahead for some buyers is connectivity. You get Bluetooth 5.3 with simultaneous dual-device connection and a claimed range of about 20 meters, plus a 3.5 mm jack so the headphones work wired as well as wireless — handy for a plane seatback screen, a desktop, or a dead battery. Build-wise, the enclosure is metal and plastic, the earcups swivel, the headband adjusts across multiple levels, and the memory foam earmuffs are aimed at long wear. The whole thing folds for storage.
Buy it if you want maximum battery, wired-or-wireless flexibility, and a foldable travel form. Skip it if you want app-based sound tuning, ambient sound transparency levels, or a specifically lightweight build.
• Best for battery life → TECKNET Noise Cancelling Headphones. Up to 70 hours standard, 45 with ANC, versus Sony's 35 hours with noise cancelling on.
• Best for sound customization → Sony WH-CH720NL. App EQ, DSEE processing, and 360 Reality Audio give you far more control over the final sound.
• Best for adjustable noise cancelling → Sony WH-CH720NL. Twenty ambient sound levels beat a simple on/off ANC button.
• Best for wired listening → TECKNET Noise Cancelling Headphones. The 3.5 mm jack is the deciding feature if you ever want to plug in.
• Best for lighter wear → Sony WH-CH720NL. At 192 g it's explicitly designed around long-session comfort.
• Best for travel storage → TECKNET Noise Cancelling Headphones. The foldable, swivel-cup design packs down; Sony's doesn't list a folding mechanism.
• Best for calls and multipoint → Sony WH-CH720NL. Precise Voice Pickup, beamforming mics, and wind noise reduction are built for conversations.
• Best value pick → TECKNET Noise Cancelling Headphones. In my opinion, the playtime, dual connectivity, and 36-month registered warranty make it the stronger practical package for the money-conscious buyer.
In my opinion, I'd buy the Sony WH-CH720NL if sound quality and smart features are what I care about most — the processor, app tuning, ambient control, and lighter build make it the more refined everyday headphone. I'd buy the TECKNET Noise Cancelling Headphones if I wanted to charge less often, plug in when needed, and fold them into a bag without a second thought. Neither is "better" in the abstract; the deciding question is whether you value tuning and refinement or endurance and flexibility. If you're still weighing it, check the current price on Amazon using the button on this page — that's often what tips the decision.
They're over-ear or in-ear headphones that connect over Bluetooth and use active noise cancelling — microphones that pick up outside sound and cancel it — to reduce what you hear around you. Both products here are over-ear wireless models with ANC.
Built-in mics sample ambient noise and the headphones generate opposing sound to reduce it. Sony does this with Dual Noise Sensor technology and the Integrated Processor V1 across 20 adjustable levels; TECKNET uses ANC rated at 95% noise reduction, switched on with a button.
For pure endurance, TECKNET's up to 70 hours standard (45 with ANC) and 10-minute quick charge for about 4 hours is hard to argue with, and the 3.5 mm cable covers seatback audio. For comfort on a long haul, Sony's 192 g build is the lighter option.
Based on the specs, Sony WH-CH720NL has the deeper audio toolkit: DSEE upscaling, app EQ, and 360 Reality Audio support. TECKNET leans on 40 mm drivers for bass and clarity without app tuning — solid, but less customizable.
