• HAIMLJLBK USB C Headphones — biggest strength: DAC-based HiFi stereo tuning plus a genuinely detailed physical build (aluminum alloy C-connector, TPE twist-resistant cable, magnetic anti-tangle design, rounded tips, bundled case).
• HAIMLJLBK USB C Headphones — biggest trade-off: it's a focused in-ear wired set with sound isolation only, so there's no active noise cancellation and no wireless fallback.
• FIYUM USB C Headphones — biggest strength: broad, clearly stated fit with the newest iPhone 17 / 17 Air / 17 Pro / 17 Pro Max lineup alongside iPad Pro and Samsung S25/S24/S23, plus a very simple plug-and-play pitch.
• FIYUM USB C Headphones — biggest trade-off: the spec sheet is thin — no listed cable material, connector metal, case or magnet system, so build details are harder to judge before you buy.
• Pick HAIMLJLBK USB C Headphones if you split time between iPhone 16/15, iPad Pro and Galaxy phones and want the more rugged, travel-friendly package.
• Pick FIYUM USB C Headphones if you're on an iPhone 17-series device and want the most straightforward match with the least second-guessing.
The HAIMLJLBK USB C Headphones are a wired, in-ear set built around a DAC chip that the brand says lifts standard audio into lossless-sounding playback. The driver is a dynamic type, the earpieces use rounded tips, and the enclosure is plastic in a clean white finish. In practice, that combination is aimed at people who want a dependable wired signal path rather than a wireless connection that needs charging.
What stands out to me is the physical design. The cable is TPE and described as twist-resistant, which matters a lot if you coil your earbuds into a pocket or bag every day. The USB-C connectors are aluminum alloy, chosen for durability and corrosion resistance. There's also a magnetic system that keeps the two earpieces together when they're not in your ears, and the set ships boxed with a case. For running, gym sessions, cycling, commuting or study sessions, that's a genuinely practical bundle — the kind of thing that survives being thrown in a backpack.
Controls are handled on a remote: media control for calls, playlists and volume, so you're not digging your phone out mid-workout. Noise control is sound isolation, which means the rounded tips physically block some surrounding noise rather than cancelling it electronically. It's rated for adults and carries a one-year manufacturer warranty.
Who should skip it: if you specifically need active noise cancellation for flights or loud trains, or you want to be free of a cable entirely, this isn't the tool for that job.
FIYUM USB C Headphones: Who It's For
The FIYUM USB C Headphones take a similar core idea — wired USB-C in-ears with a built-in mic, remote volume control and a DAC chip for HiFi stereo sound — and aim it at the very newest iPhones. The product is positioned around the iPhone 17, 17 Air, 17 Pro and 17 Pro Max, with iPad Pro and Samsung S25/S24/S23 also named. If you've just upgraded to a 17-series phone and want a cable that simply works, that naming removes a lot of the guesswork.
The design details are simpler: white plastic in-ear housings with rounded tips, a dynamic driver, and sound isolation as the noise-control approach. The pitch leans hard on plug-and-play — no battery to charge, no pairing, no power anxiety. That's the real argument for wired earbuds in 2026, and FIYUM states it plainly. The brand also mentions ergonomic, noise-isolating tips that keep surrounding sound down for work, study and sport, and describes a clear 3D-style soundstage.
The audience is broader here: adults, teens and youths are all listed, which tells you this is pitched as a household-friendly, everyday pair rather than a specialist product. There's a one-year manufacturer warranty, and the brand explicitly invites buyers to reach out with questions — a service-forward stance that some shoppers value.
Who should buy it: iPhone 17-family owners, teens and students who want a low-fuss wired set, and anyone who'd rather not think about charging another device.
Who should skip it: if you want the extra physical details — a specific cable material, metal connectors, a carry case, a magnet system — the FIYUM listing doesn't spell those out, so you're buying on the core promise rather than the fine print.
• Best for the newest iPhone → FIYUM USB C Headphones. The 17 / 17 Air / 17 Pro / 17 Pro Max fit is stated directly.
• Best for mixed-device households → HAIMLJLBK USB C Headphones. iPhone 16/15, iPad Pro and the Galaxy S20-through-S23 range are all covered.
• Best build detail on paper → HAIMLJLBK USB C Headphones. Aluminum alloy connectors, TPE twist-resistant cable, magnets and a bundled case.
• Best for teens and students → FIYUM USB C Headphones. The age range spans adult, teen and youth.
• Best for workouts and travel → HAIMLJLBK USB C Headphones. The anti-tangle cable, secure in-ear fit and case suit a gym bag or carry-on.
• Best for zero-battery simplicity → either. Both are wired and plug-and-play; neither needs charging.
• Best for active noise cancellation → neither. Both rely on passive sound isolation from the ear tips, not electronic ANC.
• Best for people who want fewer unknowns → HAIMLJLBK USB C Headphones. More of the build is documented in the spec sheet.
In my opinion, the HAIMLJLBK USB C Headphones are the stronger buy for most people. The DAC-based HiFi tuning, aluminum alloy connectors, twist-resistant TPE cable, magnets and included case add up to a set that looks built to survive daily abuse — and the device list covers iPhone 16/15, iPad Pro and a wide Galaxy range, which is where most USB-C shoppers actually live.
That said, if you're on an iPhone 17-series phone, I'd point you to the FIYUM USB C Headphones instead. It names your device family outright, keeps things simple, and works for the whole household. Either way, check the current price on Amazon before you commit — the numbers move, and the spec differences above are what should drive your decision.
For latency, charging and reliability, wired wins — neither of these sets has a battery to run down or a Bluetooth connection to drop. Wireless wins on freedom of movement. If you mostly listen at a desk, on a commute or while studying, wired is the calmer choice.
Both use passive sound isolation from the ear tips, not active noise cancellation. The rounded tips physically block some ambient sound, which helps on a bus or in a shared office, but neither will silence a plane cabin the way ANC over-ears do.
Based on the published specs, HAIMLJLBK gives you more to go on: aluminum alloy connectors, a TPE twist-resistant cable, magnets and a carry case. FIYUM publishes fewer build details, so you're trusting the brand's general quality claims rather than specific materials.
Check that your device has a USB-C port first — both are wired USB-C sets and won't work with Lightning-only iPhones. If you're on iPhone 16/15, iPad Pro or a Galaxy S20–S25, either fits. If you're on an iPhone 17-series model, FIYUM lists that lineup explicitly.
