If you want a single, MFi-certified USB-C earphone with a DAC chip, aluminum alloy connectors and a tangle-resistant cable for one device at a time, choose FIYUM Earphones USB C; if you need two pairs in the box, a longer 4 ft cable and a 36-month warranty for a household juggling several phones, choose wamaxlink 2.
• FIYUM Earphones USB C — biggest strength: MFi certification plus a built-in DAC chip, aluminum alloy USB-C connectors and a TPE twist-resistant cable, so it's built for clean plug-and-play audio on USB-C iPhones and other Type-C gear.
• FIYUM Earphones USB C — biggest trade-off: You get one pair, the cable length isn't specified, and the enclosure is thermoplastic elastomer rather than a harder plastic shell.
• wamaxlink 2 — biggest strength: Two pairs in one box, a stated 4 ft length, magnet-backed earbuds that roll up without tangling, and a 36-month warranty.
• wamaxlink 2 — biggest trade-off: The spec sheet lists a 3.5 mm jack alongside USB-C connectivity, which is confusing, and the ABS build is lighter-duty than metal connectors.
• Who each pick is for: FIYUM for the buyer who wants one carefully specified pair of USB-C in-ears for an iPhone 15/16/17 or Pixel; wamaxlink 2 for the buyer who wants a spare pair, a longer cable and longer warranty coverage.
The FIYUM Earphones USB C is the more focused product of the two. The headline detail is the MFi certification paired with a USB-C connector — that matters if you're plugging into an iPhone 15, 16 or 17 series phone and you don't want to gamble on whether the remote and mic will behave. Around that sits a DAC chip, which is the piece of hardware that converts your phone's digital output into something the drivers can actually play. FIYUM's description frames it as a route to lossless, detailed sound with deep bass and crisp highs; treat that as manufacturer language, but the DAC is a real, named component, not marketing filler.
Physically it reads like a workout-and-commute set. The in-ear fit uses rounded tips, the cable is TPE and described as twist-resistant, and the connectors are aluminum alloy, which resists corrosion better than plated plastic. FIYUM explicitly lists running, yoga, cycling, gym work, travel and sports as the intended use cases, and the sound isolation is passive rather than active noise cancellation. There's a one-year manufacturer warranty, and the age range covers adults, teens and youth, so it's fine as a family set too.
Who should skip it? Anyone who needs two pairs, anyone who wants a stated cable length before buying, and anyone who wants active noise cancellation rather than isolation. If you lose earbuds constantly, one pair in the box is a real risk. I'd also skip it if you're mainly plugging into a 3.5 mm device — this is a USB-C product, full stop. In my opinion, FIYUM is the pick for the buyer who cares most about a properly certified, well-built single pair for a modern iPhone.
wamaxlink 2 wins on sheer practicality of the package. You get two complete pairs of USB-C in-ears, which changes the math for anyone with a partner, a kid, or a habit of leaving earbuds in a jacket pocket. The cable is stated at 4 ft — a genuinely useful detail FIYUM doesn't give — and the earbuds have magnets on the back so they snap together and roll up without knotting. For commuting, the bus, running or climbing, that's the difference between a pair you actually carry and one that lives in a drawer.
The compatibility list is aggressively broad: iPhone 17, 17 Pro, 17 Pro Max, Air, 16 and 15 families, iPad Pro 12.9 and 11 inch, iPad Air 4th/5th, iPad Mini 6, MacBook and MacBook Pro, a long list of Galaxy S models, and a deep stack of Pixel models. The connectors are described as metal-plated to reduce poor contact, and there's a DAC chip in there too, with the brand claiming no buzzing or popping. It also advertises noise reduction and 360° surround sound from main and secondary sound holes — again, manufacturer claims, so weigh them as such.
The controls are simple and clearly spelled out: one press for play/pause, two for next track, three for previous track. You also get a 36-month warranty and 24/7 support with a 12-hour reply window, which is unusually long coverage for a wired earbud. Two things to flag honestly. First, the spec sheet lists the jack as 3.5 mm while the title and features say USB-C — that inconsistency is worth verifying before you buy. Second, the shell is ABS plastic, which is fine but not premium. I recommend wamaxlink 2 for households, commuters and anyone who wants a backup pair without buying twice.
Side-by-Side: Which Should You Choose?
• Best for two pairs in one purchase → wamaxlink 2. It ships as a 2-pack, so a couple, a family or a two-bag commuter is covered in one go.
• Best for cable length certainty → wamaxlink 2. It states 4 ft; FIYUM doesn't state a length at all.
• Best for tangle resistance → wamaxlink 2. The magnet-backed earbuds and anti-knot design are explicitly built for rolling up without tangling, whereas FIYUM relies on a TPE twist-resistant cable alone.
• Best for connector durability → FIYUM Earphones USB C. Aluminum alloy connectors with corrosion resistance beat a plain ABS build on paper.
• Best for warranty length → wamaxlink 2. 36 months plus 24/7 support versus FIYUM's 1-year manufacturer warranty.
• Best for working out and passive isolation → FIYUM Earphones USB C. FIYUM names running, yoga, cycling, gym and sports as its target use, with sound isolation via the in-ear seal.
• Best for the widest device list → wamaxlink 2. Its compatibility list spans iPhone, iPad, MacBook, Galaxy and Pixel families in detail.
• Best for audio hardware clarity → FIYUM Earphones USB C. Both mention a DAC chip, but FIYUM's spec sheet is the cleaner, more consistent one of the two.
I'd buy the FIYUM Earphones USB C for myself. The reason is simple: when I'm plugging wired earbuds into an iPhone 15, 16 or 17, I want the two things that actually cause headaches — certification and the connector — to be right, and MFi certification plus aluminum alloy USB-C connectors is the stronger combination. The DAC chip and TPE cable round it out, and the 1-year warranty is normal for this category. wamaxlink 2 is genuinely the better buy if you want two pairs, a 4 ft cable or the longer 36-month warranty, and the magnet roll-up is a nice touch. But that spec sheet listing a 3.5 mm jack next to USB-C is the kind of inconsistency I'd want resolved first. Check the current price on Amazon before you commit to either.
FAQ
how to use headphones for iphone
how to use wired headphones for iphone 15
The iPhone 15 family moved to USB-C, so a USB-C wired earphone plugs directly into the port. Press once to play or pause, twice for the next track, three times to go back — that's the control scheme wamaxlink 2 spells out. If your earbuds end in a 3.5 mm plug instead, they won't fit without a separate adapter.
how to use wired headphones for iphone 16
Same as the iPhone 15: the iPhone 16 series uses USB-C, so a USB-C earphone connects straight in, and the DAC chip inside handles the digital-to-analog conversion. Just plug and play — the remote and mic work through the connector. Both products here list the iPhone 16 family in their compatibility.
how to use wired headphones for iphone 16
There's nothing to configure. Insert the USB-C plug, make sure it's fully seated so the metal-plated contacts engage properly, and audio routes to the earbuds automatically. If you hear buzzing or popping, reseat the connector — wamaxlink 2 specifically claims its metal-plated connectors reduce poor contact.
