If you want the earbuds that cover the widest spread of USB-C phones, tablets and laptops while keeping physical volume buttons within thumb reach, choose ASKUBSKU USB C Headphones; if you need a lightweight, tangle-resistant pair aimed squarely at the iPhone 15/16/17 family and everyday workouts, choose FIYUM Earphones USB C.
• ASKUBSKU's biggest strength: an enormous compatibility list that spans iPhone 17/16/15, Samsung Galaxy S and Z series, Google Pixel, OnePlus, iPad, MacBook and more — plus a Hi-Res DAC chip and a 32-ohm dynamic driver rated 20Hz–20,000Hz.
• ASKUBSKU's biggest trade-off: the semi in-ear, 45° angled tip design sits loosely rather than sealing deep, so passive isolation is lighter than a full in-ear seal.
• FIYUM's biggest strength: a purpose-built iPhone 17/16/15 wired earphone with a DAC chip for lossless-style audio, an aluminum alloy USB-C connector, and TPE twist-resistant cabling.
• FIYUM's biggest trade-off: the published compatibility story is narrower — iPhone 15/16/17 series, Galaxy S24/S23, Pixel and iPad Pro — and it leans on a remote control rather than the broader feature set ASKUBSKU documents.
• Pick ASKUBSKU if you juggle several USB-C devices and want one pair for all of them.
• Pick FIYUM if you're an iPhone-first listener who wants a simple, cable-durable daily pair for running, yoga and the gym.
The ASKUBSKU USB C Headphones are, in my read of the spec sheet, the "one pair, many devices" option. The compatibility list is genuinely long: iPhone 17 Pro Max down through 15, the Galaxy S25/S24/S23/S22/S21 lines, the Z Flip and Z Fold families, Note 20 and Note 10, the Tab S8 through S10 Ultra, Google Pixel 10 through 6, OnePlus 13 down through 8, plus iPad Pro, iPad Air, iPad mini and MacBook. If you rotate between a phone, a tablet and a laptop all day, that breadth is the whole point — you stop thinking about which cable goes with which device.
On the audio side, ASKUBSKU documents a Hi-Res and DAC digital decoder chip feeding a 32-ohm dynamic driver with a 20Hz–20,000Hz frequency range. The pitch is straightforward: digital input, converted cleanly, so standard-resolution music comes through clear and lossless-feeling rather than thin. The in-line control block handles play/pause, track skipping, answering and rejecting calls, and volume — all without pulling the phone out of a pocket. The built-in mic means hands-free calling works too.
The physical design is where the trade-offs live. It's a 45° semi in-ear shape in a lightweight build with a LakeBlue plastic housing, and the 3.9-foot cable is oxygen-free copper with an anti-winding treatment. Semi in-ear means the tip rests at the opening of the ear canal instead of plugging it. That's comfortable for long listening sessions and keeps you a bit aware of traffic or a gym announcement, but it also means less passive noise blocking than a sealed design. It comes with a case, which matters if you're tossing it in a bag.
Buy it if you own several USB-C devices, want volume buttons and call controls on the wire, and prefer a relaxed fit over a deep seal. Skip it if you need maximum isolation on a noisy commute or you want a tip that locks in hard during sprint intervals.
FIYUM Earphones USB C are aimed at a narrower, very specific buyer: someone with an iPhone 15, 16 or 17 who wants a wired USB-C earphone and doesn't want to think about it much. The title calls out the iPhone 17/16/15 Pro Max family directly, and the description extends that to Samsung Galaxy S24/S23, Google Pixel and iPad Pro. For an iPhone-first household, that's the target.
The design choices read as durability-first. The earpiece uses rounded tips in a full in-ear shape, so you get a proper seal and the sound isolation that comes with it. The cable is TPE with a twist-resistant construction specifically to resist tangling, and the USB-C connector is aluminum alloy, which the sheet frames as corrosion-resistant and longer-lasting than a plain plastic plug. The white colorway is a neutral, everyday look. It also carries a 1-year manufacturer warranty, which is a real differentiator if you're hard on cables.
Audio is handled by a DAC chip paired with a dynamic driver, with the same "lossless, deep bass to crisp highs" positioning you'd expect in this category. Controls are remote-based with a built-in mic and volume control, and the fit is described for extended use across running, yoga, cycling, travel, gym sessions and sports. The age range spans adult, teen and youth, so it works as a family pair too.
Buy it if you're on an iPhone 15/16/17, you want a sealed in-ear fit for the gym, and you value a reinforced cable and a metal connector. Skip it if you need one pair that also covers a MacBook, a Galaxy Tab, an older Pixel or a OnePlus phone — ASKUBSKU documents far more ground there.

• Best for a sealed, isolating fit → FIYUM Earphones USB C. Full in-ear rounded tips versus ASKUBSKU's semi in-ear 45° design.

• Best for on-wire volume control → ASKUBSKU USB C Headphones. Push-button controls cover volume, playback, track skip and calls.
• Best for workouts and sports → FIYUM Earphones USB C. The sheet names running, yoga, cycling and gym use directly.
• Best for travel and commuting → ASKUBSKU USB C Headphones if you want one pair across devices, but FIYUM if you want more noise blocked out.
In my opinion, the right call depends on how many USB-C devices you actually carry. If you're an iPhone 15, 16 or 17 owner who just wants a dependable wired pair for the gym and the commute, I'd buy FIYUM Earphones USB C — the sealed in-ear fit, the reinforced TPE cable, the aluminum connector and the 1-year warranty are exactly what wears out first on cheap earbuds.
If, like a lot of people, your day involves a phone plus a tablet or a laptop, I'd buy ASKUBSKU USB C Headphones. The compatibility list is the deciding factor, and the DAC chip, 32-ohm driver and push-button controls make it the more versatile tool. Check the current price on Amazon before you commit, since that's the one spec I can't compare for you.
how to use wired headphones for iphone 15
The iPhone 15 moved to USB-C, so a USB-C wired earphone plugs straight into the charging port — no adapter needed. Both ASKUBSKU and FIYUM list iPhone 15 support, so you plug in, and playback routes through the earbuds automatically.

It works the same way as the iPhone 15: the USB-C port doubles as the audio output. FIYUM's sheet names the iPhone 16 series explicitly, and ASKUBSKU lists iPhone 16, 16 Plus, 16 Pro and 16 Pro Max in its compatibility range.

On a USB-C iPhone, just connect the earphone to the port and press play — the in-line remote handles volume, track skipping and calls. On an older Lightning iPhone, neither of these USB-C models is the right connector, so you'd need a different cable entirely.

Confirm your iPhone has a USB-C port first, then plug in and use the on-wire buttons. If you want volume control on the cable, ASKUBSKU's push-button controls cover it; FIYUM uses a remote control with a built-in mic for the same job.
