If you want a feature-dense wired USB-C earbud with a smart DAC chip, in-line volume buttons and the widest device compatibility list here, choose Poihiom USB-C Headphones; if you need a lightweight white everyday headset with three sizes of silicone tips and a longer tangle-free cable for commuting and workouts, choose KENSUKA USB C.
• Poihiom USB-C Headphones — biggest strength: a built-in smart DAC chip paired with a full 3-button in-line controller (volume plus a multi-function button for calls, voice wake-up and track control), and a very broad USB-C compatibility list spanning iPhone, Samsung Galaxy, Pixel, iPad, MacBook and OnePlus.
• Poihiom USB-C Headphones — biggest trade-off: it is a green plastic-and-silicone in-ear bud with passive noise cancellation only, so it relies on fit and tip seal rather than active circuitry to block sound, and the documentation is thin on cable length and tip sizes.
• KENSUKA USB C — biggest strength: a comfortable, lightweight ergonomic in-ear design that ships with three sizes of soft silicone ear tips and a 4-foot (1.2 m) tangle-free cable, which is a genuinely practical combination for commuting, workouts and long calls.
• KENSUKA USB C — biggest trade-off: fewer documented specs overall — no stated frequency range or driver type, a 120-ohm impedance that is on the higher side for a phone-driven earbud, and only one color option (white).
• Who each pick is for: Poihiom for the buyer who wants maximum device compatibility and the most control buttons; KENSUKA for the buyer who prioritizes fit options, cable length and an all-day lightweight feel.
The Poihiom USB-C Headphones are built around two ideas: plug-and-play reliability and control. The headline spec is the built-in smart DAC chip, which the data sheet says is there to maintain high-resolution acoustics from your device and to avoid buzzing, popping or other digital-to-analog conversion artifacts. That matters because a lot of USB-C earbuds live or die on that little chip — it is the part that turns a digital USB-C signal into something an analog driver can actually play. A dynamic driver covering 20 Hz to 20,000 Hz sits behind it, which is the standard full-range window for in-ear audio.
The second idea is control. There is a 3-button in-line controller with a microphone. Volume buttons handle loudness, and the main button covers answer/end calls, play/pause, next/previous track, fast-forward/rewind and intelligent voice wake-up. In practice, that means you can run a whole commute without pulling your phone out — take a call, skip a podcast ad, nudge the volume down when the train gets loud. The mic plus passive noise cancellation and sound isolation round it out as a call-and-listen tool rather than a pure music bud.
As for who should buy it: this is the pick for someone who owns more than one USB-C device and does not want to think about whether the buds will work. The compatibility list is unusually long — iPhone 17/16/15, Galaxy S25 Ultra through S20 series plus Z Fold and Z Flip, Pixel 7 Pro down through the 6 series, iPad 10, iPad Air 4th/5th, iPad Pro 2018–2022, iPad Mini 6th, MacBook 12", MacBook Air 13" 2020, MacBook Pro 13"/14"/15"/16" 2023, and a long OnePlus run from the 11 back to the 7 Pro. It also comes in green with a 1-year warranty, which is a small but real reassurance.
Who should skip it? If you want a specific fit guarantee out of the box, this listing does not document how many ear tip sizes are included, and the color choice is limited to green. If you need a stated cable length before you buy, Poihiom does not give one here while KENSUKA does — that is a legitimate reason to lean the other way.
KENSUKA USB C takes the opposite approach. Instead of a long spec sheet, it leans on comfort and the daily-use details. The in-ear design is described as lightweight and ergonomic, and it ships with three sizes of soft silicone ear tips so you can actually dial in a seal. That seal is not cosmetic — with passive noise cancellation only, a good tip fit is the entire noise-blocking mechanism. Three sizes means a much better chance of getting there than a one-size-fits-most bud.
The cable is the other standout: 4 feet (1.2 m) and tangle-free. For anyone who has fought a knotted 3-foot cord on a train or in a gym bag, that extra length and the tangle-resistant jacket are meaningful, everyday quality-of-life features. The in-line remote covers play, pause, skip tracks, volume and answer/hang-up, so the control set is comparable in spirit to Poihiom's.
Audio is handled by an advanced digital DAC chip, with the brand describing powerful bass, clear mids and crisp highs, plus a mic tuned to keep calls free of static. One spec worth flagging honestly: the impedance is listed at 120 ohm. Higher impedance generally means a headphone wants more voltage to reach the same loudness, so on a phone or a slim laptop you may find yourself using more of the volume range than with a lower-impedance bud. It is not a dealbreaker on USB-C, which supplies a digital signal the internal chip handles, but it is a real number and worth knowing.
Side-by-Side: Which Should You Choose?
• Best device compatibility → Poihiom USB-C Headphones. The enumerated list covers iPhone, Galaxy, Pixel, iPad, MacBook and OnePlus models in unusual detail.
• Best for fit and comfort → KENSUKA USB C. Three sizes of soft silicone tips plus a lightweight ergonomic shape is the better bet for long wear.
• Best for cable length and cable management → KENSUKA USB C. 4 feet (1.2 m) and tangle-free beats an unspecified length.
• Best documented audio specs → Poihiom USB-C Headphones. Dynamic driver, 20 Hz–20,000 Hz, and a smart DAC chip for clean conversion.
• Best for button-heavy control → Poihiom USB-C Headphones. Volume plus a main button covering calls, voice wake-up, play/pause, track skip and fast-forward/rewind.
• Best for calls on the go → either, with a lean to KENSUKA USB C. Both have mics and in-line remotes; KENSUKA's static-free calling claim and fit options give it a slight edge for all-day wear.
• Best for a specific color → Poihiom USB-C Headphones (green) if you want something other than white.
• Best warranty clarity → tie. Poihiom states a 1-year warranty; KENSUKA carries the Amazon Standard Warranty.
In my opinion, I would buy the Poihiom USB-C Headphones. The smart DAC chip, the fully documented 20 Hz–20,000 Hz dynamic driver, the three-button controller with voice wake-up, and above all that long, specific compatibility list make it the safer purchase for someone juggling a phone, a tablet and a laptop. The green finish and 1-year warranty are a nice bonus. I would only switch to KENSUKA USB C if fit and cable length are my top two priorities — the three tip sizes and 4-foot tangle-free cord are genuinely strong, and the 120-ohm impedance is the one spec that gives me pause. Check the current price on Amazon for both before you commit, since that can shift the math.
Both are wired USB-C buds and both list iPhone 15/16/17 family support. Poihiom enumerates the models in more detail, including Pro Max variants. In my opinion Poihiom is the safer pick if you want the compatibility spelled out.
Yes. KENSUKA documents a 4-foot (1.2 m) tangle-free cable. Poihiom does not state a cable length in its product information, so if cable length matters to you, KENSUKA is the one with the concrete answer.
Neither has active noise cancellation. Both use passive noise cancellation and sound isolation, which depends on how well the tips seal. KENSUKA ships three sizes of silicone tips, which gives you more chances to get a proper seal, so I would give it the edge there.
Both are in-ear wired buds with in-line controls, which suits workouts as long as the cable does not snag. KENSUKA's lighter ergonomic build, tangle-free 4-foot cable and multiple tip sizes make it the more workout-friendly of the two in my opinion.
