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 headphone with a built-in DAC, an inline remote for calls and music, ear-hook cable clamps and a two-year quality-assurance service, choose Sicodo Headphones USB C; if you need a plug-and-play USB-C earbud that also fits tablets, laptops and the latest iPhones, ships with a carrying case and spare eartips, and is aimed at smaller ears, choose AIAUXAI USB C Earbuds.
• Sicodo Headphones USB C — biggest strength: a built-in DAC chip for 24-bit digital audio over Type-C, plus an inline mic/volume remote, cable clamps and a longer quality-assurance window.
• Sicodo Headphones USB C — biggest trade-off: it's a plain black plastic in-ear with no carry case or spare eartips in the box, and the listing is written around Samsung and iPhone phones rather than tablets and computers.
• AIAUXAI USB C Earbuds — biggest strength: extremely broad device compatibility (iPhone, Samsung, Google Pixel, OnePlus, iPad, MacBook, Lenovo, Dell, HP, Chromebook) and a bundle that includes a carrying case and two extra pairs of eartips.
• AIAUXAI USB C Earbuds — biggest trade-off: sound isolation is passive rather than active, the enclosure is plastic in pink, and the spec sheet gives fewer audio figures to reason about.
• Who each pick is for: Sicodo is the pick if you want a phone-first wired earbud with an inline remote and a longer warranty; AIAUXAI is the pick if you want one USB-C earbud that moves between your phone, tablet and laptop and comes with a case.
Sicodo's pitch is straightforward: a plug-and-play in-ear wired headphone that plugs into a USB-C audio jack and just works. The headline spec is the built-in DAC chip, which the description frames as delivering 24-bit digital audio on Type-C devices. In plain terms, that means the earbud handles the digital-to-analog conversion itself instead of relying on whatever the phone provides — a sensible design choice for phones that dropped the headphone jack but still push audio out over USB-C. The driver is dynamic, with a stated frequency range of 20Hz–20,000Hz and 32 ohm impedance, which is the kind of load a phone's USB-C output can drive without trouble.
Who should buy it: someone whose primary device is a Samsung Galaxy or iPhone with USB-C and who wants a no-fuss wired earbud with call controls, cable management and a stated 24-month quality-assurance service with 24-hour online support. Who should skip it: anyone who needs earbuds for a MacBook, iPad or Windows laptop, anyone who wants a carry case or spare tips included, or anyone who wants color options — this one is black plastic only.
AIAUXAI USB C Earbuds: Who It's For
AIAUXAI takes the opposite approach: instead of narrowing to phones, it aims at almost everything with a USB-C audio jack. The compatibility list in the data sheet is genuinely long — iPhone 15 through 17 series including the 16e and 17e, Samsung Galaxy S8 through S26 plus the A-series and Z Fold/Flip lines, Google Pixel 2 through 10 Pro XL, OnePlus Nord and numbered models, iPad Pro, iPad Air, iPad Mini, MacBook Air and MacBook Pro, plus Lenovo Yoga/ThinkPad/IdeaPad, Dell XPS, HP and Samsung Chromebooks. If your drawer has three different USB-C devices in it, that breadth is the whole reason to pick these.
The bundle backs that up. You get the earbuds, a black carrying case and two spare pairs of eartips. That's the difference between an earbud you keep in a bag and one that lives loose in a pocket gathering lint. AIAUXAI also specifically positions these for smaller ears, describing them as more comfortable than traditional in-ear earbuds and able to stay snugly in place without falling out — the kind of claim worth weighing if you've had trouble getting earbuds to stay put.
On audio, AIAUXAI uses a DAC digital decoder chip for clear audio and effective noise isolation, with a dynamic driver, a 20Hz–20,000Hz range and 105 dB sensitivity. Note the wording: this is sound isolation, meaning passive blocking from the tip seal, not active noise cancellation. Controls are inline and cover volume, track skip, play/pause and answer/end/reject calls. The color is pink with a black case, which is a real consideration if you wanted something neutral.
Side-by-Side: Which Should You Choose?
• Best for phone-only use with active noise cancellation → Sicodo Headphones USB C. Its noise control is listed as active, and the design is clearly aimed at Galaxy and iPhone owners.
• Best for multi-device owners → AIAUXAI USB C Earbuds. The compatibility list spans phones, tablets, laptops and Chromebooks; Sicodo centers on phones.
• Best for a complete in-box kit → AIAUXAI USB C Earbuds. Carrying case plus two spare pairs of eartips versus the earbud alone.
• Best for cable management while moving → Sicodo Headphones USB C. The included cable clamps are a small but genuinely useful addition for running, working or sleeping.
• Best for smaller ears → AIAUXAI USB C Earbuds. It's the one that explicitly frames its shape around staying snug in smaller ears.
• Best for longer warranty coverage → Sicodo Headphones USB C. It states a 24-month quality-assurance service with 24-hour online support, against AIAUXAI's stated 1-year warranty.
• Best for a neutral look → Sicodo Headphones USB C. Black plastic, no surprises; AIAUXAI is pink with a black case.
• Best for call controls on either → a tie. Both offer an inline mic with answer, end and reject call functions and volume control.
In my opinion, the AIAUXAI USB C Earbuds are the safer buy for most people, purely because one pair covers your phone, your tablet and your laptop, and it arrives with a case and spare tips — the two things you'll miss first. I'd only steer toward Sicodo Headphones USB C if your listening happens almost entirely on a Galaxy or iPhone, if active noise cancellation matters more to you than passive isolation, or if you want the longer quality-assurance window and the cable clamps. Both are wired USB-C in-ears with a dynamic driver and an inline remote, so the real decision is scope: one device done thoroughly, or many devices done conveniently.

FAQ

AIAUXAI, yes — its list covers iPad Pro, Air and Mini, MacBook Air and Pro, Lenovo, Dell, HP and Chromebooks. Sicodo's description is written around phones, so I'd treat it as a phone-first earbud.
