If you want a complete wired over-ear headset you can wear straight out of the box, choose Coby Over-Ear Headphones; if you need a way to plug your existing 3.5mm wired headphones into a USB-C phone or tablet that has no headphone jack, choose YGKSAA 4PCS.
• Coby's biggest strength: it's a finished product — over-ear cups, a built-in mic with a one-touch button, an adjustable headband, and a 3.5mm jack that works with anything that has an aux port.
• Coby's biggest trade-off: it only works where a 3.5mm socket exists, so a modern phone with no headphone jack can't drive it on its own.
• YGKSAA's biggest strength: four identical USB-C-to-3.5mm adapters with a built-in DAC chip, so your existing wired headphones keep working on USB-C devices with no drivers to install.
• YGKSAA's biggest trade-off: it is not a headset — no earcups, no cable-free listening, and it won't help at all on a device that already has a 3.5mm jack.
• Buy Coby if you want one pair of headphones for a laptop, Chromebook, tablet or classroom device with an aux port.
• Buy YGKSAA 4PCS if you already own good wired headphones and just need to bridge them to USB-C hardware.
Coby's pitch here is simple: an old-school wired over-ear headset that just works. The 3.5mm jack plugs into universal AUX ports, which is why Coby frames it around laptops, Chromebooks, tablets, MP3 players and other classroom or office gear. There's no pairing, no charging, no app. You plug in and you're listening. For anyone who has ever watched a kid fight a Bluetooth pairing screen five minutes before a virtual class, that alone is the selling point.
The spec sheet backs up the "just plug it in" idea. Dynamic drivers, a 20Hz–20,000Hz frequency range and 32-ohm impedance — that's a standard, easy-to-drive load, the kind of thing a laptop headphone output handles without fuss. Coby also leans into bass, describing the tuning as amplifying lower frequencies, so if you mostly listen to hip-hop, EDM, podcasts with a lot of low-end, or game audio, that's the flavor you're getting. The over-ear cushioned pads are listed as passive noise isolation, which means they physically block some outside sound — no battery, no active circuitry, no hiss when the music stops.
The mic is the part that makes this a work-and-school tool rather than a pure music pair. There's an integrated microphone with a one-touch button for calls, virtual classes and online meetings, and Coby positions it for kids, teens and adults alike. The headband adjusts for most head sizes, the enclosure is plastic, and it ships in white. Coby rates it for a 90-day manufacturer warranty.
YGKSAA 4PCS: Who It's For
YGKSAA's product is a different category entirely, and I want to be clear about that up front — it is not headphones. It's a four-pack of USB-C-to-3.5mm female adapters, the little dongle you plug into a USB-C port so a standard 3.5mm headphone plug has somewhere to go. If your phone, tablet or notebook dropped the headphone jack, this is the bridge back to the wired headphones you already own.
The headline feature is the built-in DAC chip. Digital-to-analog conversion is exactly what a USB-C port needs before it can feed analog headphones, and YGKSAA describes the chip as high-resolution and shielded against current interference, which is the brand's way of saying it's aiming for clean, noise-free audio rather than a muffled pass-through. Plug-and-play is the second pillar: no software, no drivers, no setup menu. You connect the 3.5mm plug first, then the USB-C end, adjust volume the first time, and put your headphones on.
Compatibility is broad on paper: Samsung S20/S20+/S20 Ultra, Pixel 4/4+/4XL, iPhone, iPad, MacBook, Google Pixel and more USB-C devices. But read the fine print, because it matters. Phones that already have a 3.5mm jack are not supported — this is only for USB-C-only audio. Devices with recording functions, like microphones and sound cards, need a level-4 interface, and a three-level plug is playback only. YGKSAA also states plainly that Apple's microphone and in-line wire controls are not supported, and that button functions and the mic don't work with Apple headphones. On supported Android-style headsets, the function keys can handle calls, volume and pause, but don't assume that carries over everywhere.
Physically it's small, light and white with a crystal finish, with a single USB-C port and a compact 3.5mm socket designed to resist looseness. The 4-pack is the practical bit: one for your bag, one for the car, one at the desk, one as a spare. YGKSAA backs it with a 12-month warranty and email support.
Who should buy it: anyone with a USB-C phone or tablet and a favorite pair of wired headphones or earbuds they refuse to give up. Who should skip it: anyone who needs actual headphones, anyone with a device that still has a headphone jack, and anyone expecting full mic and remote-button support on Apple headsets.
• Best for a complete, ready-to-wear solution → Coby Over-Ear Headphones. Earcups, cable, mic and headband all included.
• Best for reviving headphones you already own → YGKSAA 4PCS. It converts USB-C audio to a 3.5mm socket, nothing more.
• Best for calls on a laptop or Chromebook → Coby Over-Ear Headphones. The integrated mic and one-touch button are built for meetings and virtual classes.
• Best for USB-C-only phones → YGKSAA 4PCS. A 3.5mm headset has no path into a jack-less phone without an adapter like this.
• Best for passive noise reduction → Coby Over-Ear Headphones. The cushioned over-ear pads physically block some outside sound; the adapter does nothing for isolation.
• Best for travel and commuter bags → YGKSAA 4PCS. Four tiny dongles take up less space than one pair of headphones, and you can leave one wherever you listen.
• Best for kids, teens and shared school devices → Coby Over-Ear Headphones. Adjustable headband, wired simplicity, no pairing or charging to manage.
• Best for bass-forward casual listening → Coby Over-Ear Headphones. Coby tunes this pair toward amplified low frequencies with a 20Hz–20,000Hz range.
In my opinion, these two aren't really rivals — they solve opposite halves of the aux-wired problem. If you want to listen and talk on a laptop, Chromebook or tablet that has a 3.5mm port, I'd buy Coby Over-Ear Headphones: it's the whole package, and the built-in mic plus adjustable headband make it a genuinely useful school-and-work tool. If you already love a pair of wired headphones and your phone is USB-C-only, I'd buy YGKSAA 4PCS instead — four plug-and-play adapters with a DAC chip is the more sensible fix than replacing headphones you like. Only buy both if you're covering a household with mixed devices. Check the current price on Amazon before you commit, since that's the one variable I can't weigh for you.
FAQ
how to make aux cable with headphones
how to use wired headphones without headphone jack
You need an adapter that turns your device's port into a 3.5mm socket. The YGKSAA 4PCS does exactly that for USB-C devices: plug the 3.5mm end in first, then the USB-C end, adjust volume the first time, and press play. It's plug-and-play, with no drivers required.
how do i connect my wired headphones to my phone
First check what your phone has. If it has a 3.5mm jack, plug straight in — a pair like the Coby Over-Ear Headphones works immediately. If it only has USB-C, use a USB-C-to-3.5mm adapter such as the YGKSAA 4PCS. Note that phones with a 3.5mm jack are not supported by that adapter, and Apple headset mics and in-line controls won't work through it.
are these two products compatible with each other
Yes, in one direction. The Coby headphones end in a standard 3.5mm plug, so on a USB-C device you can pair them with the YGKSAA adapter to get sound. Just remember the adapter is playback-focused for many headsets, and mic or button support varies by device and headset brand.
