If you want a simple, rugged 3.5mm-to-3.5mm cable that just works with the headphone jack you already have, choose QianLink 2; if you need to plug wired headphones into a phone or tablet that only has USB-C, choose YGKSAA 4PCS. These two products solve opposite halves of the same problem, which is why the "versus" question here is really about your ports, not about audio quality.
• QianLink 2 — biggest strength: a 3.3ft/1m male-to-male 3.5mm TRS aux cable with gold-plated connectors, a pure copper shell and a double-braided nylon jacket rated for 20000+ bends. It's the classic "connect two things that both have a headphone jack" cable.
• QianLink 2 — biggest trade-off: it only works where a 3.5mm port already exists on both ends. It cannot add a jack to a phone that doesn't have one, and it carries audio only — no inline mic or volume controls are listed.
• YGKSAA 4PCS — biggest strength: four USB-C-to-3.5mm-female adapters in one pack, each with a built-in DAC chip, plug-and-play with no drivers, so you can leave one on your desk, one in your bag and one in the car.
• YGKSAA 4PCS — biggest trade-off: it's an adapter, not a cable. Phones that already have a 3.5mm jack aren't supported, and the button/mic functions don't work with Apple headphones. It also needs a four-pole (level 4) interface for anything with a microphone.
• Who each is for: QianLink 2 for anyone wiring up a car stereo, speaker, iPod or pair of wired headphones that already has a 3.5mm jack. YGKSAA 4PCS for anyone whose phone, tablet or laptop dropped the headphone jack and left them with USB-C only.
The QianLink 2 is a two-pack of 3.3ft braided aux cables. Each one is male-to-male with a 3-pin 3.5mm TRS connector, so it's built for the plainest job in audio: taking the headphone output of one device and feeding it into the input of another. Car stereo, home stereo, portable speaker, wireless audio receiver, radio — anything with a 3.5mm aux port. The specs also list headphones, iPod, iPad, laptops, tablets and MP3 players, which tells you the cable is meant to be a universal jumper rather than a niche part.
The build is the interesting part. Gold-plated connectors resist corrosion, the copper shell is there to reduce signal loss, and the enameled wire core is what carries the stereo signal. The nylon double braid is rated for 20000+ bends, and the listing explicitly calls it tangle-free. I'd read that combination as a cable designed to live in a glovebox or a backpack pocket and survive it. The round, grey nylon jacket is also less likely to snag than a rubberized cable, which matters more than people expect when you're fishing a cord out of a bag one-handed.
In my opinion, this is the right buy if you already have the ports you need and you're tired of cheap aux cables dying at the connector. The two-pack is genuinely useful: one permanently in the car, one at home. Skip it if your phone has no headphone jack — this cable can't fix that. Skip it too if you need inline volume or call controls, because none are listed here. This is a straight audio-transmission part: plug and play, nothing more.
The YGKSAA 4PCS is a four-pack of USB-C-to-3.5mm-female adapters. Each dongle has one USB-C male plug on one end and a 3.5mm jack on the other, with a built-in DAC chip handling the digital-to-analog conversion. That chip is the whole point: a USB-C port outputs a digital signal, and your wired headphones need an analog one. The listing claims the DAC shields against current interference and eliminates music noise, which is the failure mode you'd otherwise hear as hiss or buzzing.
Compatibility is where you need to read carefully. The supported list includes Samsung S20/S20+/S20 Ultra, Pixel 4/4XL, iPhone, iPad, MacBook, notebooks and other USB-C devices. Two limitations stand out. First, phones that still have a 3.5mm jack are not supported — this is purely for devices that lost theirs. Second, button functions and the microphone don't work with Apple headphones, and the listing notes that devices with recording functions like microphones and sound cards need a level 4 interface, while a three-level plug is playback only.
Where this product earns its place is convenience and redundancy. Four adapters means you stop carrying one dongle between rooms. The finish is a white crystal look, it's small and light, and there's no software or driver install — you plug the 3.5mm end in first, then the USB-C end, and adjust volume the first time you use it. The manufacturer lists a 12-month warranty and says support replies within 24 hours. If you want one adapter per bag, desk and car, this is the more practical shape of the same idea.
• Best for devices that already have a 3.5mm jack → QianLink 2. It's a straight male-to-male aux cable built for car stereos, speakers, receivers and wired headphones.
• Best for phones and tablets with only USB-C → YGKSAA 4PCS. It adds the headphone jack your device doesn't have.
• Best for durability in rough use → QianLink 2. Double-braided nylon, copper shell and a 20000+ bend rating are the headline specs here.
• Best for having spares everywhere → YGKSAA 4PCS. You get four adapters, so one can live in each bag, room or vehicle.
• Best for call and volume-button control → neither, on the data given. QianLink 2 lists no inline controls, and YGKSAA's button functions don't work with Apple headphones.
• Best for recording or mic input → YGKSAA 4PCS, with a caveat. It needs a level 4 interface for mics and sound cards; a three-level plug is playback only.
• Best for cable length flexibility → QianLink 2. Its 3.3ft/1m run gives you slack between a phone and a car stereo; the YGKSAA is a short dongle.
If I had to pick one, I'd buy the YGKSAA 4PCS, because the modern problem is usually a missing jack rather than a missing cable — and four adapters covers your phone, tablet and laptop at once. But that's only if your devices are USB-C. If your gear already has 3.5mm ports and you just want a cable that won't fray in a month, I'd take the QianLink 2 without hesitation; its braided build and two-pack value fit that job better than any dongle. Buy for your ports, not for the brand name.
FAQ
how to make aux cable with headphones
how to use wired headphones without headphone jack
You need an adapter that converts your device's port to a 3.5mm jack. The YGKSAA 4PCS does this over USB-C with a built-in DAC chip, so you plug the 3.5mm end into your headphones, then the USB-C end into your phone or tablet and adjust the volume.
how do i connect my wired headphones to my phone
It depends on your phone's port. If it has a 3.5mm jack, a cable like the QianLink 2 works directly. If it's USB-C only, use the YGKSAA adapter instead — note that phones with a 3.5mm jack aren't supported by that adapter, and Apple headphone mic and button controls won't work through it.
