• JYCHEYI White USB C — biggest strength: A dedicated inline remote with push-button control for volume, playback and calls, plus a long list of supported iPhone, iPad, MacBook, Galaxy and Pixel models. 1.2 m cord, 15 g, 20 Hz–20 kHz dynamic driver.
• JYCHEYI White USB C — biggest trade-off: One pair per pack, and there's no active noise cancellation — the design relies on a sound-insulating build to block outside noise passively.
• MAS CARNEY USB C Earbuds — biggest strength: You get two pairs in a single pack, a 120-ohm dynamic driver, and compatibility that stretches across iPhone 15/16/17, iPad, MacBook, Galaxy S25 and even Xiaomi, Huawei, Honor, Oppo and Vivo.
• MAS CARNEY USB C Earbuds — biggest trade-off: Control is voice-based rather than a physical remote with volume buttons, and it's a plastic-and-silicone build in black or white only.
• Who each pick is for: Choose JYCHEYI White USB C if you want one pair with tactile volume and call controls for an iPhone 15/16/17, iPad or MacBook. Choose MAS CARNEY USB C Earbuds if you want a spare pair for a second device and the broadest possible compatibility across Android brands.
The JYCHEYI White USB C is a single pair of wired in-ear buds with a USB-C jack, a 1.2 m (3.93 ft) cord and an inline remote. That remote is the headline feature here: push-button control for volume, music playback and answering or ending calls. If you've ever fumbled for your phone mid-walk just to skip a track, that's exactly the problem this design solves. It's a small thing on paper and a big thing in daily use.
Sound-wise, JYCHEYI leans on a sound-insulating material to cut external noise passively and produce clear stereo output, with a 20 Hz–20,000 Hz dynamic driver — the standard full-range figure, so expect normal, well-rounded audio rather than anything exotic. The rounded-tip, in-ear fit is described as ergonomic, and the polycarbonate enclosure keeps each bud light at 15 g total. The USB-C connection covers a genuinely wide spread: iPhone 17, 16 and 15 series, iPad Pro, Air, mini and 10th-gen iPad, MacBook Air and Pro from 2018 through the M4 era, plus Galaxy S20–S23 families, Google Pixel 2 through 8, and a long OnePlus list.
Buy it if: you want one dependable pair with physical volume and call buttons, you're on an iPhone 15/16/17 or an iPad/MacBook, and you like a clean white finish that matches Apple hardware.
MAS CARNEY USB C Earbuds: Who It's For
The MAS CARNEY USB C Earbuds (model TH9) take a different angle: value through volume. You get a pack of two pairs, which is the single most practical thing about this product. Keep one at your desk and one in your bag. Hand one to a family member. Leave one plugged into a laptop so it's always there. For households with more than one USB-C device owner, that math is hard to argue with.
The spec sheet also shows something the JYCHEYI doesn't list: 120-ohm impedance. Higher impedance generally means the driver needs more power to reach the same loudness, but it can also mean tighter control and less hiss on a decent source. In practice, expect these to sound a little quieter at the same volume step than a low-impedance bud — you'll just nudge the slider up. The driver is dynamic, 20 Hz–20,000 Hz, with a plastic-and-silicone build in black or white.
Compatibility is where MAS CARNEY genuinely pulls ahead. Beyond iPhone 15/16/17 and iPad, it explicitly lists Samsung Galaxy S25 FE/Edge/S25/S24/S23 series, the A-series budget phones (A16, A17, A26, A33, A53, A55 and more), Z Flip and Fold generations, Xiaomi Redmi, Huawei Honor, Oppo and Vivo. If you're on a mid-range Android phone from a brand the JYCHEYI list ignores, this is your safer bet. The trade-off: control is listed as voice-based rather than a physical remote, so there's no button cluster for volume — you'll be using your phone or your voice.
Buy it if: you want two pairs, you own a non-Samsung Android phone like a Xiaomi, Honor, Oppo or Vivo, or you simply want a spare set without buying twice.
Skip it if: you rely on inline buttons to change volume or take calls without touching your phone.
• Best for physical controls → JYCHEYI White USB C. Push-button volume, playback and call control on the cord. MAS CARNEY lists voice control instead.
• Best for two people or two devices → MAS CARNEY USB C Earbuds. A pack of two pairs, full stop.
• Best for iPhone 15/16/17, iPad and MacBook owners → either. Both cover Apple's USB-C lineup; JYCHEYI names M1–M4 MacBooks and 2018–2025 models explicitly.
• Best for mid-range Android brands → MAS CARNEY USB C Earbuds. Xiaomi Redmi, Huawei Honor, Oppo and Vivo appear on its list; JYCHEYI's Android coverage centers on Samsung, Pixel and OnePlus.
• Best for lighter weight → JYCHEYI White USB C. 15 g total for the headphone, with a polycarbonate enclosure.
• Best for louder output from a weak source → JYCHEYI White USB C (in my opinion). No impedance figure is listed for it, while MAS CARNEY's 120 ohm will typically need a higher volume setting.
• Best for a color you can match to a black phone or case → MAS CARNEY USB C Earbuds. It comes in black or white; JYCHEYI is white only.
• Best for hands-free driving and shopping → JYCHEYI White USB C. The inline remote is built for answering and ending calls without reaching for your phone.
In my opinion, most people torn between these two should take the MAS CARNEY USB C Earbuds. Two pairs plus the widest compatibility list on the page is the more flexible buy, especially if anyone in your household uses a Xiaomi, Honor, Oppo or Vivo phone. The 120-ohm driver is a real consideration — you'll turn the volume up a little — but it's not a dealbreaker.
That said, I'd pick the JYCHEYI White USB C without hesitation if buttons matter to you. Volume, playback and calls on the wire is the kind of convenience you notice every single day, and the white polycarbonate shell pairs naturally with Apple hardware. One pair, done properly.
MAS CARNEY ships two pairs in one pack, so on a per-pair basis it's the more economical route if you need a spare. JYCHEYI gives you one pair with a physical remote. Check the current price on Amazon before deciding, since that's what tips the math.
Yes. Both list the iPhone 15, 16 and 17 series along with iPad models. MAS CARNEY also names iPhone 16e and iPhone Air; JYCHEYI names iPad Pro, Air, mini and 10th-gen iPad plus MacBook Air and Pro.
No. Both data sheets list noise control as "None." JYCHEYI relies on sound-insulating materials for passive isolation, and MAS CARNEY doesn't claim noise cancellation either. Expect the seal from the rounded tips to do the work.
Both use a dynamic driver with a 20 Hz–20,000 Hz range, so the frequency coverage is identical on paper. The clearest difference is MAS CARNEY's listed 120-ohm impedance, which usually means you'll push the volume higher, and JYCHEYI's stated lossless stereo tuning with noise-reducing materials.
Only with JYCHEYI. Its inline remote has push-button volume, playback and call controls. MAS CARNEY lists voice as the control method, so volume changes happen on your device.
