If you want the widest confirmed device compatibility and a straightforward wired USB-C earbud that just plugs in and works across a huge list of Samsung and Pixel phones, choose MAS CARNEY USB C Headphones; if you need a shorter tangle-free cable, a clothing clip, three sizes of silicone tips and a built-in DAC chip for cleaner sound, choose Bordsek USB C.
• MAS CARNEY USB C Headphones — biggest strength: an extremely long, explicitly listed compatibility roster covering Galaxy A, S, Note-era and Pixel models, plus a 120 ohm dynamic driver rated 20–20,000 Hz.
• MAS CARNEY USB C Headphones — biggest trade-off: the sheet lists no DAC chip, no cable length, no clothing clip and no spare ear tips, so you get exactly one pair of tips and whatever cable length the model ships with.
• Bordsek USB C — biggest strength: a built-in DAC chip paired with 14.2mm dynamic drivers, plus practical extras — a 4ft tangle-free cable, a clothing clip and three sizes of silicone tips.
• Bordsek USB C — biggest trade-off: its compatibility list is described in much broader, vaguer terms (iPhone 17e/17/16, Galaxy S26/S25, Moto, Apple), and the data sheet lists no impedance or frequency range figures.
• Who each pick is for: MAS CARNEY for buyers who want a documented match with a specific Galaxy or Pixel model; Bordsek for buyers who care more about cable management, fit options and onboard audio processing.
The MAS CARNEY USB C Headphones are, at their core, a compatibility play. The data sheet spells out an unusually detailed list of supported Samsung Galaxy A-series handsets — everything from the A01, A10, A11 and A12 up through the A53 5G, A54 5G, A55 5G, A35 5G, A25 5G, A15 5G and the newer A57 and A37 — and then continues through the Galaxy S line from the S10 era all the way to the S26, S26+ and S26 Ultra, including the FE and Edge variants. Pixel 9 is named too. If you own one of those phones and you want a wired USB-C earbud that the listing explicitly says is built for it, that specificity is genuinely useful.
What you're getting technically is a single dynamic driver with a 120 ohm impedance and a 20–20,000 Hz frequency range, in an in-ear, rounded-tip, plastic-bodied design in black. The 120 ohm figure is the interesting one: it's a relatively high impedance for a phone earbud, which usually means the driver is designed to be driven a little harder rather than being hyper-sensitive. In practice that's a design choice, not a defect — but it's worth knowing that very low-output sources may need more volume travel than you'd expect from a typical cheap earbud.
The remote handles control, and the noise control approach is passive sound isolation rather than anything active. That means the fit does the work: if the tip seals well in your ear, outside noise drops; if it doesn't, it won't.
Who should skip it: anyone with a 3.5mm-only phone (the sheet is blunt that these produce no sound there), anyone whose case blocks the USB-C port, and anyone who wants spare tips, a cable clip or a known cable length. Also skip if you're on an iPhone model not listed — the sheet names iPhone 17, 16 and 15, but the detail is built around Samsung and Pixel.
One practical note the sheet raises and that I'd take seriously: the USB-C plug has to seat fully, with no visible gap. A thick case lip can stop that from happening, and a half-seated plug is the single most common reason people conclude a wired USB-C earbud is "dead on arrival."
Bordsek USB C: Who It's For
The Bordsek USB C is the more feature-loaded of the two on paper. The headline item is the built-in DAC chip sitting alongside 14.2mm dynamic drivers — a DAC converts the digital signal inside a USB-C connection into analog audio, and having one onboard is the difference between a clean, properly decoded signal and one that depends entirely on whatever the phone does by default. Bordsek pairs that with a claimed tuning emphasis on bass plus clear mids and highs. That's a marketing description, not a measurement, but the hardware behind it — a dedicated DAC plus a larger-than-typical 14.2mm driver — is a legitimate reason to expect a fuller low end.
The controls are more granular than MAS CARNEY's too. A middle button handles play, pause and call answering; triple and double clicks skip tracks; there's volume up and down; and the sheet mentions voice assistant support across Siri, Gemini and Bixby. So if you use a voice assistant on the go, this one is set up for it by design.
Then there's the physical package, and this is where Bordsek pulls ahead for daily use. A 4ft tangle-free cable with a clothing clip is a genuinely thoughtful combination — 4ft is short enough that it doesn't snag on door handles or bag straps, and the clip keeps the cable from swinging when you walk. Three sizes of silicone tips (S/M/L) mean you can actually chase a proper seal instead of accepting whatever fit you get. Lightweight, ergonomic, in-ear, black.
Who should buy it: commuters, walkers and anyone who wears earbuds for long stretches and wants fit options, cable management and onboard audio processing. Also a good fit if you bounce between an iPhone and an Android phone, since the sheet names iPhone 17e/17/16 alongside Galaxy S26/S25, Moto and Apple devices.
Who should skip it: anyone who needs a documented match with an older or mid-range Galaxy A-series model, because the Bordsek sheet doesn't enumerate one. And if you specifically want passive noise isolation called out as a feature, note that Bordsek's noise control field lists none — the isolation here comes purely from how well the silicone tips seal. The sheet also notes an adult age range, so it isn't positioned as a kids' accessory.
• Best for confirmed phone compatibility → MAS CARNEY USB C Headphones. The A-series and S-series list is exhaustive; Bordsek's is broad but shallow.
• Best for sound-hardware design → Bordsek USB C. A dedicated DAC chip plus 14.2mm dynamic drivers is a more complete audio chain than a bare dynamic driver.
• Best for fit and comfort over long sessions → Bordsek USB C. Three tip sizes (S/M/L) versus a single set.
• Best for cable management → Bordsek USB C. 4ft tangle-free cable plus a clothing clip.
• Best for voice assistant users → Bordsek USB C. Siri, Gemini and Bixby support are explicitly named.
• Best for a plain, low-feature wired earbud → MAS CARNEY USB C Headphones. One driver, one remote, sound isolation, done.
• Best for higher-impedance design and a published frequency range → MAS CARNEY USB C Headphones. 120 ohm, 20–20,000 Hz.
• Best for a Pixel 9 owner → MAS CARNEY USB C Headphones. Pixel 9 is named on that sheet; Bordsek's doesn't call it out.
In my opinion, the Bordsek USB C is the better buy for most people. The combination of a built-in DAC chip, 14.2mm drivers, three sizes of silicone tips, a 4ft tangle-free cable and a clothing clip is simply a more complete everyday package, and those extras are the things you actually notice after a week of use.
I'd only steer you to the MAS CARNEY USB C Headphones if your specific phone model is on its list and isn't clearly covered by Bordsek — an older Galaxy A-series handset, for instance, or a Pixel 9. In that case, documented compatibility beats nicer accessories, because an earbud that's confirmed to work with your phone is worth more than one that merely might.
Either way, check the current price on Amazon before deciding, since that's the one variable that can flip this call.
FAQ
Only if your phone has an active USB-C port and no reliance on a 3.5mm jack. Both sheets warn that 3.5mm-only devices produce no sound, and both stress that the plug must be fully inserted with no gap. MAS CARNEY lists far more specific models, so check its list first if your phone is a Samsung mid-ranger.
It helps. Bordsek's built-in DAC handles the digital-to-analog conversion inside the earbud itself, which is why its sheet emphasizes stereo sound and bass response. MAS CARNEY's sheet doesn't mention a DAC, so its audio depends on the driver and the phone's own output. Neither approach is wrong — it's a difference in how much of the audio chain lives in the earbud.
Bordsek, in my opinion. The three sizes of silicone tips let you find a real seal, and the 4ft cable with a clothing clip keeps things from tugging. MAS CARNEY relies on passive sound isolation with the tips it ships, so the fit you get is the fit you get.
