How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired USB-C earphone with a metal-bodied build, a bundled carry case and a long 18-month warranty for running and everyday listening, choose BENEWY USB C Headphones; if you need a lightweight, tangle-resistant set with aluminum alloy connectors and a strong focus on sport-friendly comfort, choose HAIMLJLBK USB C Headphones.
• BENEWY — biggest strength: A 14.2 mm dynamic driver paired with a built-in DAC chip, plus a full inline remote (play/pause, track skip, volume, call answer/reject) and a magnetic neck-tether design.
• BENEWY — biggest trade-off: The cable is TPE with a stated bend life, but the overall package is bulkier — a hard protective case and heavier materials mean it's less of a featherweight pick.
• HAIMLJLBK — biggest strength: An ergonomic in-ear fit with twist-resistant TPE cable, anti-tangle design and aluminum alloy USB-C connectors that resist corrosion — a clear nod to sweat and movement.
• HAIMLJLBK — biggest trade-off: Less detail is published about the driver and acoustics — no stated driver size, impedance or frequency range — so you're trusting the "HiFi stereo with DAC" description rather than hard numbers.
• Who BENEWY is for: Buyers who want a durable, feature-rich wired set with a case and a longer warranty, and who value documented audio specs.
• Who HAIMLJLBK is for: Runners, gym-goers and cyclists who prioritize a light, tangle-free, corrosion-resistant build for sport.
The BENEWY set is the more "specified" of the two. It uses a 14.2 mm dynamic driver, and the data sheet lists a 32 ohm impedance, a 20 Hz – 20,000 Hz frequency range and 110 dB sensitivity. Those are the kinds of numbers that tell you this is a standard, efficient wired in-ear that a phone's USB-C port can drive without any fuss. A built-in DAC chip is there specifically to reduce loss during transmission, which matters when you're going straight from a phone with no headphone jack.
Where it earns its keep is control and durability. The inline remote handles play/pause, next/previous track, volume up/down and call answer/reject, so you rarely need to pull the phone out mid-run. The magnetic construction lets the buds snap together around your neck so they don't swing or get lost between uses. The cable is TPE with a stated 10,000-plus bend life, and the enclosure mixes aluminum, metal, plastic, rubber and TPE — in my opinion that's a build aimed at surviving daily pocket-and-bag life rather than being disposable.
Who should buy it: someone who wants one wired USB-C earphone to cover commuting, calls and running, and who likes having a protective case and an 18-month warranty backing the purchase. Who should skip it: if you want the absolute lightest possible sport bud and don't care about published audio specs, the extra material and hard case here work against you. It ships as a single blue unit with a spare pair of eartips, a case and a manual.
HAIMLJLBK takes a different angle. The pitch is comfort and movement: an ergonomic in-ear fit meant to stay put through running, yoga, cycling, travel, gym workouts and sports. The cable is twist-resistant TPE with an anti-tangle design, and the USB-C connectors are aluminum alloy, which the data sheet calls out for corrosion resistance — a sensible detail when sweat is part of the equation. Built-in magnets let the buds clip together when you're not using them.
On audio, it's described as HiFi stereo with DAC technology, driving a dynamic driver. Here's the honest caveat: unlike BENEWY, there's no published driver size, impedance or frequency range, so you can't compare acoustics on paper — you're going on the feature description alone. The enclosure is plastic in white, and it ships boxed with a case. Warranty is stated as one year manufacturer coverage.
Who should buy it: the runner or gym regular who wants a light, tangle-free set with corrosion-resistant connectors and doesn't need a spec sheet to feel confident. Who should skip it: if you like comparing impedance and frequency numbers before buying, or you want the longer warranty, the BENEWY sheet gives you more to work with.

If I were buying one for running, I'd take the BENEWY USB C Headphones. In my opinion, the combination of a published 14.2 mm driver, a DAC chip, a full inline remote, a magnetic neck tether, a protective case and an 18-month warranty gives me more to rely on for a set I'll sweat in several times a week. The HAIMLJLBK USB C Headphones is the better pick if corrosion resistance and a featherweight, anti-tangle build matter more to you than specs and warranty length. For most runners who want one durable wired set to cover workouts and calls, BENEWY is my recommendation.
Both are wired in-ear sets suited to running. HAIMLJLBK leans harder into sport with aluminum alloy corrosion-resistant connectors and a twist-resistant, anti-tangle cable. BENEWY counters with a magnetic neck tether, a protective case and a longer warranty.
Yes. BENEWY lists an HD microphone with an inline remote for volume, playback and calls. HAIMLJLBK lists a built-in mic with remote control for calls, playlists and volume. Both are wired USB-C, so they plug straight into modern phones and tablets.
BENEWY publishes concrete numbers: 14.2 mm dynamic driver, 32 ohm impedance, 20 Hz–20,000 Hz range and 110 dB sensitivity. HAIMLJLBK describes HiFi stereo with DAC technology and a dynamic driver but doesn't publish driver size, impedance or frequency range.
Both are affordable wired options, so check the current price on Amazon before deciding. If you want the most features and coverage for your money — case, magnetic tether, full remote and an 18-month warranty — I'd lean BENEWY. If you want the lightest sport-focused build, lean HAIMLJLBK.
