How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an old-school 3.5 mm wired earbud built for school kids, small ears and long-term peace of mind, choose UliX Rider; if you need a modern USB-C plug-and-play earphone for an iPhone 15 or newer, a recent Samsung Galaxy, a Pixel, an iPad or a USB-C laptop, choose AIAUXAI USB C Headphones.
• UliX Rider's biggest strength: a 48 Ω dynamic driver with passive noise isolation, magnet-backed metal housings, an anti-tangle TPE-reinforced cable and a 5-year warranty — plus a 3.5 mm jack that works with almost any older phone, tablet or laptop.
• UliX Rider's biggest trade-off: it uses a 3.5 mm plug, so it simply won't fit a USB-C-only device like an iPhone 15 or a modern Galaxy without an adapter.
• AIAUXAI's biggest strength: a native USB-C connector with plug-and-play audio, an inline multi-function button for play, pause and volume, plus a DAC chip and high-fidelity stereo drivers for fuller bass and crisper treble.
• AIAUXAI's biggest trade-off: it only works where a USB-C audio jack exists, and its warranty coverage is 1 year versus UliX's 5.
• Pick UliX Rider if you're buying for a student, a kid, a small-eared listener, or anyone with a headphone jack who wants a rugged, metal-shelled daily beater.
• Pick AIAUXAI if your phone, tablet or laptop has moved fully to USB-C and you want a single cable that carries both sound and mic.
The UliX Rider is a pink, in-ear wired headphone with a metal shell and rounded silicone tips. The heart of it is a 48 Ω dynamic driver rated from 20 Hz to 20,000 Hz. That impedance figure matters more than it sounds: 48 Ω is a fairly stiff load, which generally means the earbuds pull a bit more power from the source and can reward you with tight, controlled output on decent hardware rather than the thin, splashy sound you get from cheap low-impedance buds. UliX pairs that with passive noise isolation — no batteries, no ANC circuitry, just a sealed in-ear fit and internal sound-absorbing holes that cut down on outside rumble. The result is a warmer, bass-forward tuning aimed at pop, hip-hop and movie soundtracks rather than clinical studio monitoring.
The ergonomics are clearly aimed at smaller ears. UliX says the shape was developed around ear-canal measurements from thousands of people, and it shows in the rounded-tip, low-profile design. If you've ever had earbuds that constantly work their way loose or feel like they're prying your ear open, this is the category of fit you want. The TPE thermoplastic rubber cable is reinforced and treated to resist tangling, and the two magnets inside each metal housing let you clip the buds together around your neck or snap them shut in the included pouch — a genuinely useful detail for anyone who yanks earbuds out a dozen times a day.
On the call side, there's a built-in MEMS microphone with noise reduction, and the remote on the cable handles call control. That's a practical setup for a laptop, a desktop or a phone: you get a mic close to your mouth and a physical button you can find by touch.
So who should buy it? Students, kids, commuters with older phones, and anyone with small ears who wants a pair they can lose in a backpack and not worry about. UliX backs it with a 5-year warranty, which is unusually long for this category and a real signal about how the company views the build. Who should skip it? If your only devices are USB-C — an iPhone 15 or later, a recent Galaxy, a modern MacBook — the 3.5 mm plug is a dead end unless you're willing to carry a dongle. And if you want inline volume buttons, note that the Rider's control is a remote with call control rather than a dedicated volume rocker.
The AIAUXAI USB C Headphones are the answer to a very 2026 problem: phone makers deleted the headphone jack and left you with one port that has to do everything. This is a wired, in-ear earphone with a USB-C plug on the end, a dynamic driver rated 20 Hz to 20,000 Hz, 105 dB sensitivity, and a built-in DAC chip. That last part is the important one. A DAC converts the digital signal into analog inside the earbud, so you get clean, properly amplified audio straight from the port instead of relying on whatever the device's internal path does. Paired with high-fidelity stereo drivers, it's tuned for enhanced bass and clear treble — an energetic, consumer-friendly sound rather than a flat, neutral one.
Plug and play is the whole pitch, and it's a good one. AIAUXAI explicitly says no adapters and no software: you push the connector into a USB-C audio jack and you're listening. The compatibility list is long and specific, covering iPhone Air, iPhone 17 series, iPhone 16 series and iPhone 15 series; a wide spread of Samsung Galaxy S and A models plus Z Fold and Z Flip; Google Pixel from the early models up through the Pixel 10 family; OnePlus Nord and numbered flagships; iPad Pro, iPad Air, iPad Mini and iPad 10th/11th gen; and MacBook Air and MacBook Pro in their USB-C generations. If you've been burned by "works with USB-C" listings that actually mean "works with some USB-C," that breadth is worth noticing.
Controls are handled in-line: an HD microphone for calls and a multi-function button for play, pause and volume. That's a cleaner control story than the UliX remote, especially if you take a lot of calls while walking or working. AIAUXAI also uses the same magnetic trick — the two buds snap together so you can wear them around your neck without the cable turning into a knot — and throws in a storage bag plus two pairs of eartips and a carrying case.
The trade-offs are honest ones. It's USB-C only, so anything with a 3.5 mm jack is off the table. The enclosure is TPE rather than metal, and the warranty is 1 year rather than 5. And it's grey with a black case — a plain, functional look rather than the UliX's pink styling.
Buy it if your daily carry is a USB-C phone, tablet or laptop and you want one cable that does music, calls and volume without a dongle dangling off your pocket. Skip it if you're shopping for a young kid's first pair or you still live on a 3.5 mm device.
• Best for modern phones (iPhone 15+, Galaxy S24/S25, Pixel) → AIAUXAI. Native USB-C, no adapter needed.
• Best for older devices and laptops with a headphone jack → UliX Rider. The 3.5 mm plug is universal on legacy gear.
• Best for kids, students and small ears → UliX Rider. Rounded tips, low-profile metal shells and a reinforced anti-tangle cable.
• Best for call and volume control → AIAUXAI. It has a dedicated multi-function button plus an HD mic; the UliX remote focuses on call control.
• Best for long-term ownership confidence → UliX Rider. A 5-year warranty against AIAUXAI's 1 year is a big gap.
• Best for a clean digital signal → AIAUXAI. The built-in DAC chip and 105 dB sensitivity point to easy, dynamic output from a USB-C port.
• Best for bass-forward music on a budget-friendly metal build → UliX Rider. The 48 Ω driver and passive isolation are tuned for warmth and punch.
• Best for plug-and-play simplicity on a tablet or MacBook → AIAUXAI. No software, no dongle, just the port.
If I had to pick one, I'd buy the AIAUXAI USB C Headphones for myself — because in my opinion the connector you can actually use beats the better warranty you can't. The DAC chip, the inline volume button and the long compatibility list make it the more practical daily driver for anyone on a current phone, tablet or laptop.
That said, I'd recommend the UliX Rider without hesitation for a kid, a student, or a small-eared listener with a 3.5 mm device, where the metal build, the anti-tangle cable and the 5-year warranty do more real work than a USB-C plug ever could. Match the connector to your device first; everything else follows.
Not universally — they solve different problems. The UliX Rider wins on warranty length, metal housings and 3.5 mm compatibility. The AIAUXAI wins on USB-C plug-and-play, inline volume control and a built-in DAC. Pick based on the port your devices actually have.
Yes, according to the listed compatibility they support iPhone 15, 16 and 17 series plus iPhone Air. They will not work with older Lightning iPhones, since those don't have a USB-C audio jack.
No. The UliX Rider uses a 3.5 mm jack, so it needs a device with a headphone port or a separate adapter. If your phone is USB-C only, the AIAUXAI is the more direct fit.
Value depends on your device and how long you plan to keep the earbuds. The UliX Rider's 5-year warranty and metal build favor long-term use; the AIAUXAI's DAC, USB-C fit and inline controls favor convenience. Since prices change, check the current price on Amazon before deciding.
