How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a spare pair always within reach and inline volume control you can adjust without touching your phone, choose TECHAIRLINE 2; if you need the lightest possible single pair of USB C earbuds with a simple button remote and nothing extra to carry, choose SoFunMoky USB C.
• TECHAIRLINE 2 biggest strength: it ships as a 2-pack, so you get a second identical set for a bag, desk or backup without buying again.
• TECHAIRLINE 2 biggest trade-off: the plastic build and 32 g weight per listed item make it the bulkier, less pocket-friendly option.
• SoFunMoky USB C biggest strength: at 5 g it is the lighter, more minimal pick, and the single-pair packaging keeps things simple.
• SoFunMoky USB C biggest trade-off: one pair only, and the control scheme is a basic button remote with no volume control listed.
• Who each pick is for: TECHAIRLINE 2 suits people who lose earbuds, share them, or want a backup pair; SoFunMoky USB C suits one-person, one-pair minimalists.
TECHAIRLINE 2 is a wired USB C in-ear headphone built around a 10 mm dynamic driver, with a 16 ohm impedance, 50 dB sensitivity and a 20 Hz – 20,000 Hz frequency range. In plain terms, that's a standard, easy-to-drive spec sheet: a USB C connection supplies the signal and the power, so the earbuds don't need to fight for volume the way high-impedance gear does. The oval earpiece shape and in-ear placement are aimed at a snug, isolating fit, and the listed noise control is sound isolation rather than active noise cancellation — so expect the physical seal of the tips to do the work, not electronics.
The clearest reason to pick this one is in the box. It's sold as a 2-pack, and the package includes both eartips and a headband-style accessory. If you're the kind of person who leaves earbuds in a jacket pocket, keeps a pair at the office and another at home, or has a household where more than one person needs a USB C set, buying two at once is genuinely practical. The inline remote also gives you button control plus volume control, which matters more than people admit: on a lot of USB C phones and tablets, on-screen volume steps are coarse, and a hardware rocker is faster for podcasts, calls and quick mutes.
Who should skip it? If you want the absolute smallest, lightest thing in your pocket, the 32 g listed weight and the two-pair packaging work against you. And if you already own one good USB C set and don't need a spare, you're paying attention to the wrong product — the second pair is the whole point.
SoFunMoky USB C is the same core recipe on paper: a 10 mm dynamic driver, 16 ohm impedance, 50 dB sensitivity, 20 Hz – 20,000 Hz range, in-ear placement, plastic enclosure, white finish, USB C wired connection. Where it diverges is philosophy. It's listed at 5 g, which tells you the design intent is light and unobtrusive rather than armored. The earpiece shape is described simply as in-ear, the style is "Classic," and it ships as a single pair with eartips in a retail box.
The control setup is the other difference worth understanding. SoFunMoky lists button control with a touch method, while TECHAIRLINE 2 lists an inline remote with volume control. Neither is objectively better — it depends on whether you want a hardware volume rocker on the cable or a simpler single-button interaction. If you mainly take calls and skip tracks and rarely touch volume because your phone is in your hand anyway, the simpler scheme is fine.
Who should buy it? Someone who wants one clean, light pair, plugs it into a USB C phone, tablet or laptop, and doesn't want a drawer full of spares. It's also the more natural fit for a single user who keeps their earbuds in one place. Who should skip it? Anyone who wants a backup pair, wants volume control on the wire, or wants the slightly more substantial build feel that comes with a heavier, two-pair product. Age range is listed as adult, so it's positioned as a straightforward personal-use product rather than a family multipack.
Side-by-Side: Which Should You Choose?
• Best for having a spare → TECHAIRLINE 2. Two identical pairs in one retail box, eartips included.
• Best for the lightest carry → SoFunMoky USB C. 5 g listed versus 32 g, and a single pair instead of two.
• Best for a shared household or multi-device setup → TECHAIRLINE 2. One pair for the phone, one for the laptop bag.
• Best for a first USB C wired set with no extras → SoFunMoky USB C. Simple, single, retail-boxed.
• Best for driver specs → a tie. Both list a 10 mm dynamic driver, 16 ohm, 50 dB, 20 Hz – 20,000 Hz.
• Best for noise handling → a tie. Both rely on sound isolation, not active cancellation.
• Best warranty confidence → a tie. Both list 1 year.
In my opinion, TECHAIRLINE 2 is the smarter buy for most people, and it comes down to one thing: two pairs and inline volume control for a purchase that otherwise looks spec-identical to its rival. The 10 mm driver, 16 ohm impedance and 20 Hz – 20,000 Hz range are the same on both, so the tiebreakers are packaging and controls — and TECHAIRLINE 2 wins both. I'd only steer you to SoFunMoky USB C if you specifically want the lightest single pair and don't care about a spare or a volume rocker. Either way, check the current price on Amazon before deciding, since that's the one number that can flip this call.
how to use usb c headphones on android phone
Plug the USB C connector into the phone's charging port. Both TECHAIRLINE 2 and SoFunMoky USB C are wired USB C headphones, so there's no pairing step and no battery to charge. If audio stays on the speaker, check your phone's USB audio or "USB accessory" setting.
how to use usb c headphones on android
Same idea across Android devices: connect to the USB C port, then confirm the phone has switched audio output. Both of these sets use a wired USB C connection with a 16 ohm, 10 mm dynamic driver, so they run directly off the port. Use the inline or button control for calls and playback.

Plug into a USB C port on the Mac — most current Macs have them. Both products are wired USB C, so the Mac should recognize them as an output device; pick them in Sound settings if it doesn't switch automatically. TECHAIRLINE 2's inline remote adds volume control on the cable.

Connect to the PS5's USB C port and set the output to USB headset in the audio settings. Both are wired USB C in-ear sets with microphones, so they can handle game audio and chat. Note that both rely on sound isolation rather than active noise cancellation.
