How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C listening setup built for detail and long, focused sessions, choose AuiDi USB C Headphones; if you need a straightforward wired USB-C earbud for a Samsung Galaxy phone, choose VIFIGEN Samsung Earbuds. That's the honest split for anyone shopping for audiophiles-grade wired listening in 2026 — one leans into driver size and a full accessory kit, the other keeps it minimal and Samsung-first.
• AuiDi's biggest strength: a 14.2 mm dynamic driver with a stated 20 Hz–200,000 Hz frequency range, 32 ohm impedance and 110 dB sensitivity — on paper the more "audiophile-leaning" spec sheet of the two.
• AuiDi's biggest trade-off: no active noise control, and it's strictly wired — it will not work on phones that still have a 3.5 mm jack, and AuiDi explicitly warns about that.
• VIFIGEN's biggest strength: a DAC chip paired with copper wiring and a very broad Samsung Galaxy compatibility list spanning S, A, M, Z and Note lines.
• VIFIGEN's biggest trade-off: a narrower stated frequency range of 20 Hz–20,000 Hz, no noise control, and a remote-based control method rather than the button-and-volume approach AuiDi uses.
• Buy AuiDi if you're chasing the more detailed spec sheet and want the extras in the box — for audiophiles who want a wired in-ear that plays nicely with iPhone, iPad, Pixel and Samsung.
• Buy VIFIGEN if you mainly want a no-fuss wired USB-C earbud for a Galaxy phone and don't need the accessory bundle.
AuiDi is the pick I'd point an audiophile toward first, and the reason is in the numbers. The 14.2 mm dynamic driver is larger than you'd expect at this style, and the stated frequency range runs from 20 Hz up to 200,000 Hz — a figure that matters far more for high-resolution audio playback than for casual streaming. Add 32 ohm impedance and 110 dB sensitivity, and you've got a wired in-ear that a phone's USB-C port can drive without any external amp. That combination — big driver, low-ish impedance, high sensitivity — is exactly what you want in a wired headset for audiophiles who don't want to carry a dongle DAC around.
The build backs it up. The enclosure mixes aluminum, plastic, rubber and stainless steel, the earbuds are in-ear buds with a classic style, and the package includes silicone ear tips and a protective case. AuiDi also throws in a leather bag, anti-drop silicone earplugs, and a claimed 180-day free warranty with lifetime customer service. The 4-foot cable is a sensible length for desk or pocket use, and there's a built-in microphone plus touch/button volume control.
Who should skip it? Anyone whose phone still has a 3.5 mm jack — AuiDi is upfront that if your device has both a USB-C port and a headphone jack, you're better off with a 3.5 mm set, because this one may not work. And if you want wireless freedom, this isn't it; it's wired, full stop. There's also no noise control, so buyers who want to block out a commute should look elsewhere.
VIFIGEN positions itself as the Samsung-first wired USB-C earbud, and the compatibility list is genuinely enormous. Beyond the Galaxy S26, S25, S24 Ultra, S24 FE, S23, S22, S21 and S20 families, it also names the A-series, M-series, Z Fold and Z Flip lines, and the Note series going back to the Note 7 and Note FE. If your daily phone is a Galaxy — any Galaxy — VIFIGEN is the safer bet on fit and function.
The audio story is more modest: a dynamic driver with a stated 20 Hz–20,000 Hz range, and the marketing leans on a DAC chip plus copper wiring and "HiFi stereo sound." That's a reasonable recipe for clean wired playback from a phone, and the DAC chip is a legitimately useful inclusion for anyone plugging into a USB-C port. The earbuds are in-ear with rounded tips, housed in aluminum and plastic, finished in black, and controlled via a remote on the cable. There's a headphone clip in the box too.
What you don't get: no active noise control, and no volume-control button array described the way AuiDi describes its touch/button setup. The item weight of 0.04 kg and single-item package also suggest a leaner kit than AuiDi's. In my opinion, VIFIGEN is the pragmatist's choice — it's aimed at someone who wants a wired USB-C headset that just works with their Galaxy, not someone hunting the most detailed spec sheet on the shelf.
• Best for detailed audio specs → AuiDi USB C Headphones (14.2 mm driver, 20 Hz–200,000 Hz range, 32 ohm, 110 dB).
• Best for Samsung Galaxy owners → VIFIGEN Samsung Earbuds (S, A, M, Z and Note coverage is the widest of the two).
• Best for iPhone and iPad users → AuiDi USB C Headphones (explicitly lists iPhone 15/16/17 families, iPad Pro, iPad Air, iPad Mini).
• Best accessory bundle → AuiDi USB C Headphones (silicone ear tips, protective case, leather bag, anti-drop earplugs, mic).
• Best for a DAC-based wired setup → VIFIGEN Samsung Earbuds (DAC chip plus copper wiring is called out specifically).
• Best for control flexibility → AuiDi USB C Headphones (volume control plus touch and button control methods).
• Best if you still have a 3.5 mm jack → neither, honestly — AuiDi itself says to get a 3.5 mm headphone in that case.
• Best for a minimal, single-item kit → VIFIGEN Samsung Earbuds.
If I were buying for audiophiles — someone who cares about driver size, frequency range and impedance — I'd take AuiDi USB C Headphones. The 14.2 mm dynamic driver, 32 ohm impedance, 110 dB sensitivity, and a stated range that reaches far beyond the audible ceiling give it the more serious spec sheet, and the included ear tips, case and mic make it a complete wired setup for iPhone, iPad, Pixel or Galaxy. In my opinion, VIFIGEN is the better pick only if you're locked into Samsung and want the simplest possible wired USB-C earbud with a DAC chip on board.

Are AuiDi USB C Headphones better than VIFIGEN for audiophiles?
On paper, yes — AuiDi lists a larger 14.2 mm driver and a much wider stated frequency range (20 Hz–200,000 Hz) versus VIFIGEN's 20 Hz–20,000 Hz. For hi-res listening, that's the more interesting spec sheet.
Yes. VIFIGEN's listing names iPhone 17e, 17 Pro, 17 Air, Pro Max, 16 and 15, plus iPad, Pixel and OnePlus 9. So it's not Samsung-only, even though Samsung is the focus.
Yes — AuiDi lists the Galaxy S26, S25, S24, S23, S22, S21 and S20 families, plus the A-series, Z Fold/Flip and Tab S8/S7/S6/S5e. Just make sure your phone doesn't also have a 3.5 mm jack.
No. Both list noise control as "None." They're wired in-ear earbuds, so passive isolation comes from the ear tips, not active ANC.
