How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a no-fuss way to bring wired headphones back to a single USB-C phone — with spares so you're never caught without one — choose YGKSAA 4PCS; if you need two people to listen from one USB-C device at the same time, choose ZOOAUX PRO USB C. These two adapters look similar in a search results page, but they solve genuinely different problems. One is a single-output dongle sold in a four-pack; the other is a single splitter that feeds two pairs of headphones from one port. Knowing which problem you actually have is the entire decision.
• YGKSAA 4PCS — biggest strength: A built-in DAC chip for clean audio plus four identical adapters in one box, so you can leave one in a bag, one at a desk, one in the car, and still have a spare. One output, 3.5mm female.
• YGKSAA 4PCS — biggest trade-off: It's a single-listener adapter. It won't split audio to two headphones, its button/mic support doesn't extend to Apple headsets, and it won't work with phones that already have a 3.5mm jack.
• ZOOAUX PRO USB C — biggest strength: A true 1-in-2-out splitter with its own DAC chip, so two people get stereo sound from one USB-C port — plus a nylon-braided, aluminum-housed build rated for heavy repeated plugging.
• ZOOAUX PRO USB C — biggest trade-off: It's audio-only in the strictest sense: no microphone, no inline volume control, no charging, and no Nintendo Switch. And you get exactly one unit, not a set.
• Who each pick is for: YGKSAA is for the person who just wants their wired headphones to work on a USB-C phone — everywhere, with backups. ZOOAUX PRO is for couples, seatmates, siblings and study partners who want to share one screen's audio at the same time.
The YGKSAA 4PCS is the practical, everyday answer to a very common annoyance: your phone dropped the headphone jack and your favorite wired cans didn't get the memo. It's a USB-C-to-3.5mm-female adapter with a built-in DAC chip, which is the part that actually matters here — the DAC handles the digital-to-analog conversion and, per the spec sheet, is paired with shielding intended to cut current interference and keep the audio path clean. In plain terms, it's designed so music comes through clearly rather than with the hiss or crackle you get from cheap pass-through dongles. It's plug-and-play: no drivers, no software, no setup ritual.
Compatibility is broad and clearly stated: Samsung S20/S20+/S20 Ultra, Pixel 4/4 XL, iPhone, iPad, MacBook, Google Pixel and other USB-C devices. Two caveats are worth reading before you buy, because they're the kind of thing that causes returns. First, this is for devices that don't already have a 3.5mm jack — plugging it into a phone that has its own headphone port won't help you. Second, while the adapter does support the function keys on many headsets for calls, volume and pause, the sheet is explicit that button controls and the microphone are not compatible with Apple headphones. If you're an iPhone owner planning to use an Apple headset's inline mic, that's a real limitation, not a footnote.
So who should buy it? Someone with a USB-C phone or tablet and a beloved pair of wired headphones, who wants a simple, clean-sounding connection and values having spares on hand. Who should skip it? Anyone who needs to plug in two headphones at once — that's not what this does — and anyone expecting full mic and remote support from Apple-branded headsets. It carries a 12-month warranty and a stated 24-hour email support response.
ZOOAUX PRO USB C: Who It's For
The ZOOAUX PRO USB C is a different animal entirely: a 1-in-2-out headphone splitter. One USB-C plug goes into your phone, tablet or laptop, and two 3.5mm jacks come out the other end, so two people can listen to the same thing simultaneously. If you've ever tried to watch a movie on a tablet with a partner using one pair of earbuds split between you, you already understand why this exists. It's built for flights, road trips, shared playlists, kids watching a lesson together, or two people on a couch with one screen.
It also carries a built-in DAC chip, and the design intent is spelled out: rich, clear stereo sound to both outputs without the noise or volume drop that cheap passive splitters are known for. That's the key difference between a real splitter and a Y-cable — each listener gets proper stereo rather than a weakened, shared signal.
The physical build is where ZOOAUX PRO makes its strongest argument. The cable uses a flexible nylon-braided jacket to resist tangling and abrasion, with reinforced strain relief and an aluminum alloy housing at the connector ends. The sheet cites a 25,000+ plug/unplug durability test — that's a claim about repeated daily use, and it points at the failure mode that kills most adapters: the cable fraying right where it meets the plug. A light gray metallic finish rounds it out, and it comes with an 18-month warranty and 24/7 support.
Buy it if your goal is shared listening from a single USB-C port, and if you want that connection to survive being yanked in and out of a bag for years. Skip it if you need mic input for calls or gaming chat, if you want to charge while listening, or if you're buying for a Switch.
Side-by-Side: Which Should You Choose?
• Best for sharing audio with a second person → ZOOAUX PRO USB C. It's the only one of the two with two outputs.
• Best for keeping spares everywhere → YGKSAA 4PCS. Four adapters versus one changes how you live with the thing.
• Best for microphone and inline button use → YGKSAA 4PCS, with the caveat that Apple headset mics and buttons aren't supported. ZOOAUX PRO supports no mic at all.
• Best for long-term durability under heavy plugging → ZOOAUX PRO USB C, thanks to the braided jacket, reinforced strain relief, aluminum housing and the cited 25,000+ cycle durability claim.
• Best for a household with several USB-C devices → YGKSAA 4PCS. One purchase covers multiple bags, desks and cars.
• Best for movie nights, flights and road trips → ZOOAUX PRO USB C. Shared screens with two listeners is exactly its purpose.
• Best if you want the simplest possible single-listener setup → YGKSAA 4PCS. Plug in, listen, done — no second jack to think about.
• Best if you need to charge while listening → neither. Both are audio-only; ZOOAUX PRO states no charging, and YGKSAA's sheet lists no power pass-through either.
If I had to pick one for myself, I'd buy the ZOOAUX PRO USB C — but only because my actual need is shared listening, and no number of spare single adapters can do what a real splitter does. The braided build and reinforced ends also read as the more durable long-term object in my opinion. That said, if you're a solo listener who just wants wired headphones working on a USB-C phone with backups in every bag, the YGKSAA 4PCS is the smarter, more practical buy. Match the tool to the job, not the other way around. Since neither sheet lists a price, check the current price on Amazon for each before you commit.
ZOOAUX PRO USB C. It's a 1-in-2-out splitter with two 3.5mm jacks, so two people hear the same source simultaneously. YGKSAA 4PCS is a single-output adapter — even with four of them, one adapter serves one listener.
No. The spec sheet states it does not support microphone function, volume control or charging, and it's designed for TRS headphones rather than TRRS ports. If you need mic support, that's a reason to look at the YGKSAA instead.
Partially. YGKSAA supports function keys on many headsets for calls, volume and pause, but the sheet notes that button functions and the microphone are not compatible with Apple headphones. Plan on audio playback working; don't count on the inline mic.
By design, ZOOAUX PRO USB C makes the stronger durability case: nylon-braided cable, reinforced strain relief, aluminum alloy housing and a cited 25,000+ plug/unplug test. YGKSAA's advantages are simplicity and having four units as backups rather than one reinforced unit.
No. Both are plug-and-play with no drivers or software required, and each relies on its own built-in DAC chip to handle the audio conversion.
