How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a compact, pocketable USB-C to 3.5mm adapter that converts digital audio to analog at up to 24bit/192kHz and carries a 1-year warranty, choose Samsung EE-UC10JUWEGUS; if you need a longer 3.3-foot braided USB-C to aux cable with a built-in 32bit/384kHz DAC for car stereos and headphones, choose Ugreen USB C.
• Samsung EE-UC10JUWEGUS — biggest strength: a tiny single-port USB-C to 3.5mm adapter with a 1-year warranty and 24bit/192kHz digital-to-analog conversion, in a white finish that matches Samsung phones.
• Samsung EE-UC10JUWEGUS — biggest trade-off: it's a short dongle with no cable, so a snagged plug can tug directly on your phone's port; it's also audio-only and single-port.
• Ugreen USB C — biggest strength: a 3.3-foot nylon-braided cable with a 32bit/384kHz Hi-Fi DAC and aluminum alloy shells, so your phone can sit in a mount while the cable reaches the car stereo.
• Ugreen USB C — biggest trade-off: it's male-to-male and not bidirectional, so it won't connect a phone with a 3.5mm jack to a USB-C headset, and it does no charging or video.
• Who Samsung EE-UC10JUWEGUS is for: someone who wants the smallest possible adapter for wired earbuds on a USB-C phone.
• Who Ugreen USB C is for: someone who wants a cable-length solution for a car aux input, a speaker, or a desktop setup.
The Samsung EE-UC10JUWEGUS is about as simple as a dongle gets. One USB-C male connector on one end, one 3.5mm aux jack on the other, and a small body in between. Samsung's spec sheet lists the core job plainly: it converts digital audio files to analog, at up to 24bit/192kHz. That's the whole pitch, and for a lot of people that's all they need.
The listing's "specific uses" field is unusually broad for a dongle this size — it names headphones, cell phones, laptops, tablets, PCs, TVs, projectors, monitors, speakers, cameras, MP3 players, amplifiers, TV boxes, GPS units, DVD players, power banks, microphones and video game consoles. I'd treat that as a compatibility claim rather than a promise that every one of those devices will behave identically, but it does tell you Samsung built this to slot into a standard 3.5mm audio plug anywhere you find one. It's white, it weighs essentially nothing at 0.01 kg, and it comes with a 1-year warranty — a detail worth noting, because dongles are exactly the kind of accessory that gets lost or bent.
Who should buy it? If you own a USB-C phone or tablet and you still prefer wired earbuds — or you want to plug into a car, an amp or a speaker with a 3.5mm input — this is the minimal, no-fuss answer. It disappears in a pocket, and there's nothing to configure.
Who should skip it? Anyone who needs reach. If your phone lives in a dashboard mount and your car's aux port is across the console, a rigid dongle plus your headphone cable is an awkward, tug-prone combination. And if you're chasing the highest possible sample-rate spec, the 24bit/192kHz ceiling here is lower than the Ugreen cable's. That's a paper difference most listeners won't hear, but it's a real difference on the sheet.
The Ugreen USB C to Aux cable is solving a different problem. Instead of a stubby adapter, you get a 3.3-foot cable with a male USB-C connector on one end and a male 3.5mm plug on the other. Ugreen builds in a DAC chipset rated at up to 384kHz/32bit, which is the number the brand leads with, and it uses copper for signal transmission to keep the audio path stable in daily use.
The physical build is the other half of the story. Ugreen describes a nylon braided jacket with reinforced stress points, aluminum alloy shells, and anti-corrosion connectors meant to resist wear and rust. Black, 3.3 feet, braided — this is a cable designed to be plugged in and left in place, not fished out of a pocket. Ugreen even calls out the "out of the box" car scenario directly: connect your Type-C phone, tablet or laptop to a car stereo, speaker or headphones with no apps or setup.
Compatibility is broad and explicitly listed: iPhone 15/16/17 family, Samsung Galaxy S22 through S24 and Note20 series, Pixel 6 through 10, iPad mini/Pro/Air, iMac, MacBook Pro/Air, PS5, Switch 2 and "most Type C phones." Read the notes carefully, though, because Ugreen flags three limits. It is not bidirectional — it will not connect a phone that has a 3.5mm port to a USB-C headset like AirPods Max, and Ugreen explicitly notes AirPods Max support is absent. It's audio only — no charging, no video. And the connector gender is male to male, not a female jack, so it is not a replacement for the Samsung-style adapter if what you actually want is a 3.5mm socket.
Who should buy it? Commuters, road-trippers and desk workers who want their phone in a mount, cupholder or stand while the cable does the reaching. The braided jacket and 3.3-foot length are the point. If you've ever had a rigid dongle pop out mid-drive, this is the fix.
Side-by-Side: Which Should You Choose?
• Best for smallest possible carry → Samsung EE-UC10JUWEGUS. It's a single-port dongle with no cable to manage.
• Best for car aux and mounted-phone setups → Ugreen USB C. The 3.3-foot braided run lets the phone stay where it is.
• Best for highest sample-rate spec → Ugreen USB C. 32bit/384kHz versus 24bit/192kHz on the Samsung.
• Best for a 3.5mm female jack → Samsung EE-UC10JUWEGUS. The Ugreen is male-to-male and is not a port adapter.
• Best for durability in daily plugging and unplugging → Ugreen USB C. Braided nylon, reinforced stress points and aluminum shells are built for repeated handling.
• Best for warranty coverage → Samsung EE-UC10JUWEGUS. It ships with a 1-year warranty.
• Best for wired earbuds on a USB-C phone → Samsung EE-UC10JUWEGUS. Simplest path from USB-C to a 3.5mm headphone plug.
• Best for speakers, amps and desktop audio → Ugreen USB C. Longer reach and the Hi-Fi DAC claim fit stationary gear.
Before either, check the current price on Amazon — the button on this page will show it, and it's the one number that changes often enough that I won't guess at it here.
If I were buying for myself, I'd take the Ugreen USB C to Aux cable. In my opinion, the 3.3-foot braided cable with a 32bit/384kHz DAC is the more useful object for the way most people actually listen — phone in a holder, cable running to a car stereo, a speaker or a laptop dock. The Samsung EE-UC10JUWEGUS is a fine, tidy dongle and the 1-year warranty is a genuine plus, but its rigid, cable-free design is exactly what makes it annoying in a car or at a desk. If you specifically need a 3.5mm socket rather than a plug, flip that recommendation.
FAQ
Only if your headphones end in a 3.5mm plug and your phone has USB-C. The Ugreen is male USB-C to male 3.5mm and is not bidirectional, so it won't drive a USB-C headset from a 3.5mm source, and Ugreen notes it does not support AirPods Max.
No. The Ugreen listing states audio transfer only — no charging and no video. The Samsung is a single-port 3.5mm adapter with no charging passthrough either. Plan on charging separately.
That depends on the current price, which you should check on Amazon rather than take from me. Judge it by use case: the Samsung is the cheaper-feeling buy for a pocket dongle, while the Ugreen gives you 3.3 feet of braided cable and a higher DAC spec for roughly the same kind of money.
