If you want flagship-grade active noise cancellation, a wireless over-ear experience and long battery life, choose Amazon Renewed Sony ULT WEAR; if you need a wired USB-C connection that just works with laptops, phones and tablets, with zero charging involved, choose Cowyawn USB C Headphones.
• Amazon Renewed Sony ULT WEAR — biggest strength: Active Noise Cancellation with dual noise sensor technology, Bluetooth 5.2 wireless freedom, and up to 30 hours of battery (up to 50 hours with ANC off).
• Amazon Renewed Sony ULT WEAR — biggest trade-off: It's a refurbished unit with a 90-day limited warranty rather than a new-in-box product, and there's no headphone jack at all — everything runs over Bluetooth.
• Cowyawn USB C Headphones — biggest strength: True plug-and-play USB-C wired audio with an inline microphone, volume control and no battery to manage, ever.
• Cowyawn USB C Headphones — biggest trade-off: No active noise cancellation and no wireless mode — you're physically tethered to your device, and you need a USB-C port to use them.
• Who each pick is for: Pick the Sony ULT WEAR if you want to disappear into your music on a plane, train or open office. Pick the Cowyawn if you want dependable wired sound for calls, classes, gaming or desk work without ever thinking about charging.
The ULT WEAR is Sony's bass-forward over-ear model, and the headline feature here is the ULT button. Press it and you get two flavors of low-end emphasis: a punchy "powerful bass" mode for when you want the beat to hit, and a "deep bass boost" that leans into low frequencies for a more relaxed, rumbling listen. Around that sits Sony's premium noise cancellation with dual noise sensor technology, which actively works to block out whatever is going on around you rather than just muffling it.
Comfort is clearly a design priority. The earcups use moldable cushions built with a thermo-foaming process, which Sony says keeps them wrinkle-free and gives a snug, balanced over-ear fit. That matters, because over-ear headphones live or die on whether you can wear them for three hours straight. The 40 mm dynamic drivers cover a 20 Hz – 20,000 Hz range, and the enclosure and carry case are both made from recycled plastic — a nice detail if sustainability factors into your buying.
Battery is the other big argument: up to 30 hours with noise canceling on, and up to 50 hours with it switched off. There's also a quick-charge trick — a 3-minute top-up gives you roughly 90 minutes of playback, which is genuinely useful when you're walking out the door and realize you forgot to charge. Bluetooth 5.2 gives you a 10-meter range, controls are touch-based media controls, and the box includes the headphones, a connection cable, a USB cable and a reference guide.
Who should buy it: commuters, travelers, open-office workers and anyone who wants wireless freedom plus real ANC. Who should skip it: anyone who needs a wired connection (there is no headphone jack), anyone who wants a brand-new sealed product, and anyone uncomfortable with a 90-day limited warranty on a refurbished unit.
The Cowyawn pair solves a completely different problem. This is a wired, USB-C-only over-ear headphone — no Bluetooth, no pairing, no battery. You plug the USB-C connector into your device and you're listening. That makes it a natural fit for newer iPhones (15/16/17 series), MacBooks, laptops, tablets, iPads, Google Pixel phones and basically anything with a USB-C audio jack.
Sound is handled by 40 mm DLC dynamic drivers, tuned for balanced bass and treble with a clear stereo midrange — a sensible, all-round voicing rather than a bass monster. The microphone is the other core feature: Cowyawn describes HD voice pick-up with automatic wind-noise suppression, which is exactly what you want for work calls, online classes or gaming chat. There's inline volume control too, so you're not diving back into your device every time someone gets loud.
Isolation here is passive, not active. The 360-degree over-ear construction is designed to block out over 90% of ambient sound, which is a real benefit in a noisy room, but it's a seal-and-cushion approach rather than the electronic cancellation the Sony offers. The earcups are on-ear with an oval shape and faux leather/plastic build, they fold for transport, and the set comes in a violet colorway. Cowyawn backs it with a one-year replacement policy and lifetime support.
Who should buy it: students, remote workers, gamers and anyone who wants a cable they never have to charge. Who should skip it: iPhone users on Lightning, anyone who wants wireless movement, and anyone who needs active noise cancellation rather than passive isolation.

My Verdict
Yes. The Sony ULT WEAR has no headphone jack — it connects via Bluetooth 5.2 with a 10-meter range. If you need a wired connection, the Cowyawn USB-C model is the one to look at.
They support USB-C devices including the iPhone 15/16/17 series, plus laptops, tablets, MacBooks, iPads and Google Pixel phones. Older iPhones with a Lightning port are not compatible.
No. The Cowyawn uses passive noise isolation — its over-ear construction is designed to block out over 90% of ambient sound — while the Sony ULT WEAR uses active noise cancellation with dual noise sensor technology.
Check the current price on Amazon using the button on this page, and confirm your device's port. The Sony is Bluetooth-only, the Cowyawn is USB-C only, and the Sony is a refurbished unit with a 90-day limited warranty versus Cowyawn's one-year replacement coverage.
