How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a white, iPhone-and-Samsung-friendly wired USB-C earbud with a magnetic neck-wear design and a proper carrying kit, choose AIAUXAI USB C Headphones; if you need a black braided-cord earbud with multiple ear-tip sizes and a cord clip for workouts, gaming and sleep, choose Bordsek USB C.
• AIAUXAI USB C Headphones — biggest strength: In-line volume and multi-function control, a magnetic design that lets you wear the buds around your neck, plus a storage bag and two pairs of eartips in the box.
• AIAUXAI USB C Headphones — biggest trade-off: It's a white TPE-bodied earbud with sound isolation only; there's no braided cable, no cord clip and only one cable-length/colour option.
• Bordsek USB C — biggest strength: A 4ft braided cord with an included clip, three sizes of silicone tips (S/M/L) and an ergonomic in-ear shape pitched at long wear, commuting, sports and sleep.
• Bordsek USB C — biggest trade-off: The controls are push-button only (no dedicated volume control listed) and the cable is a fixed 4ft, which is short for desk or laptop use.
• Who each is for: Pick AIAUXAI if you want neck-wear convenience and easy volume control on calls and commutes; pick Bordsek if fit, tip sizing and a tangle-resistant braided cable matter more to you.
The AIAUXAI USB C Headphones are a white, in-ear wired earbud built around a USB-C plug. The headline feature is the in-line control: a multi-function button handles play, pause and volume, and there's a built-in HD microphone for calls. That combination is aimed squarely at people who take a lot of voice calls or jump between music and meetings without touching their phone. There's no adapter and no software in the setup — you plug the USB-C connector into the device and that's it.
The second thing that stands out from the spec sheet is the magnetic design. When you pull the earbuds out, the two buds snap together and hang around your neck instead of swinging loose, which reduces the tangle problem that plagues most wired pairs. AIAUXAI also includes a storage bag for the earbuds, an adapter and small accessories, plus two pairs of eartips so you can swap for a better seal. The in-ear silicone caps are there for sound isolation, and the driver setup is a dynamic driver paired with a DAC chip, rated 20 Hz to 20,000 Hz with enhanced bass and clear treble. The enclosure material is thermoplastic elastomer, which is a rubbery, flexible-feeling plastic rather than hard shell.
Compatibility is broad and clearly documented: iPhone 15 through iPhone 17 Pro Max, the Samsung Galaxy S and A lines up to S25/S26-era models, Z Fold and Z Flip, Google Pixel 2 through Pixel 10 Pro XL, OnePlus, iPad Pro, iPad Air, iPad Mini, iPad 10th/11th, MacBook Air and MacBook Pro. If your device has a USB-C audio jack, this is very likely on the list.
Bordsek USB C: Who It's For
The Bordsek USB C is a black wired in-ear earbud with a USB-C plug, and its design story is about wearability. The cable is a 4ft upgraded braided cord with an included clip, which is the practical answer to two common complaints about wired earbuds: tangling and the cable snagging on clothing. Braided sleeving generally resists the kinks that smooth rubber cables develop, and the clip lets you pin the cable to a shirt or collar so it stays put while you move.
Fit is the other pillar. Bordsek bundles three sizes of silicone tips — small, medium and large — around an ergonomic in-ear shape, and the product materials describe the fit as intended for extended wear, including sleeping, commuting and workouts. That matters more than it sounds: with in-ear buds, the tip seal is what actually delivers bass and blocks outside noise, so having three sizes to test is a genuine advantage over a one-size approach. The enclosure is silicone, and like the AIAUXAI it uses a dynamic driver rated 20 Hz to 20,000 Hz with sound isolation.
Bordsek also advertises a Hi-Res DAC chip for "zero sound loss," balanced bass/mids/highs and concert-like clarity — marketing language, but the underlying claim (a DAC in the plug) is the same category of component AIAUXAI lists. One honest note from the spec sheet itself: Bordsek flags a troubleshooting tip about enabling "USB audio routing" in Developer Options if audio cuts out on some Android devices. That's a real-world gotcha worth knowing before you buy, and it's more transparency than most listings offer.
Compatibility covers iPhone 17e/17 Pro Max/17 Pro/17 Air/17/16e/16/16 Pro Max/16 Plus, iPhone 15 series, iPad Pro, MacBook Air M4, MacBook Pro, Samsung Galaxy S26/S25/S24 lines, Z Fold 7/6, Z Flip 7 FE/6, the A-series, Google Pixel 10/9/8/7, OnePlus and general Android USB-C phones. Controls are push-button, and there's no volume control listed in the spec sheet.
Who should buy it: gym-goers, runners, side sleepers, gamers and anyone who has struggled to get a good seal from stock tips. Who should skip it: laptop and desk users who want a longer cable run, or anyone who wants dedicated in-line volume control rather than push-button commands.
• Best for call and volume control → AIAUXAI USB C Headphones. It lists an in-line multi-function button with volume control and a built-in HD microphone; Bordsek's spec sheet lists push-button control only.
• Best for fit and seal → Bordsek USB C. Three silicone tip sizes (S/M/L) versus AIAUXAI's two pairs.
• Best for cable durability and tangle resistance → Bordsek USB C. Braided 4ft cord with an included clip.
• Best for neck-wear convenience → AIAUXAI USB C Headphones. The magnetic design lets the buds clasp together when you take them out.
• Best for workouts, gaming and sleep → Bordsek USB C. The ergonomic in-ear shape is explicitly framed around extended wear, sports and gaming.
• Best for desk and laptop sessions → AIAUXAI USB C Headphones. The 4ft Bordsek cable is short for reaching a laptop port from a seated position, and AIAUXAI's kit includes a storage bag for carrying it around.
• Best for colour choice → Bordsek USB C if you want black; AIAUXAI USB C Headphones if you want white. Each brand lists only one colour, so there's no real choice within either product.
• Best for plug-and-play simplicity on Android → AIAUXAI USB C Headphones. Bordsek's own listing notes a potential USB audio routing setting to adjust if audio cuts out.
In my opinion, I'd buy the AIAUXAI USB C Headphones for daily life. The reason is simple: the features that annoy people most about wired earbuds are the cable getting tangled and not being able to control volume without pulling out the phone, and AIAUXAI solves both with the magnetic clasp and the in-line volume button, while also throwing in a storage bag and an extra pair of tips. If your priority is a secure fit during hard workouts or you sleep in your earbuds, I'd switch to Bordsek USB C instead — the three tip sizes, braided cord and clip are built for exactly that. Both are USB-C wired in-ears with a 20 Hz–20,000 Hz dynamic driver and sound isolation, so the real decision comes down to control and convenience versus fit and cable build. Check the current price on Amazon for both before you commit, since that's the one variable that can tip an even matchup like this.
FAQ
Neither is objectively "better" — they're tuned for different buyers. AIAUXAI wins on in-line volume control and the magnetic neck-wear design; Bordsek wins on tip sizing, braided cable and cord clip. Match it to how you actually use earbuds.
Yes. Both list iPhone 15, 16 and 17 series models as compatible, along with USB-C iPads and MacBooks. If your iPhone still uses Lightning, neither will work without an adapter — and neither listing includes one.
Bordsek USB C is the safer bet here, because it ships three tip sizes and a clip, and its design language targets sports and extended wear. AIAUXAI includes two pairs of tips and a magnetic clasp, which helps when the buds are off your ears, not during high-movement activity.
AIAUXAI explicitly lists a built-in HD microphone and an in-line multi-function button for play, pause and volume. Bordsek's spec sheet lists push-button controls but does not spell out microphone details, so if calls are your main use, AIAUXAI is the clearer choice on paper.
