How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a classroom-ready set of twelve wired headphones in one go, choose Konohan 12; if you need a single pair of USB-C earbuds with a mic, inline controls and a travel case for a modern phone, choose AIAUXAI USB C.
These two products get compared a lot because they both sit in the cheap-wired-audio corner of the market, but they solve completely different problems. One is a bulk pack built for shared school use. The other is a personal USB-C earbud aimed at phones and tablets that no longer have a headphone jack. Let me break down exactly where each one wins.
• Konohan 12 – biggest strength: twelve individually wrapped on-ear headphones in four mixed colors, all with adjustable headbands and a 3.5 mm jack — a ready-made class set.
• Konohan 12 – biggest trade-off: it is 3.5 mm only, so it will not plug directly into USB-C-only phones or tablets without an adapter.
• AIAUXAI USB C – biggest strength: a USB-C plug plus a built-in DAC, inline mic and volume remote, and a PU storage case for travel.
• AIAUXAI USB C – biggest trade-off: it is one pair of in-ear buds, so it is not a shared or classroom solution and it fits USB-C ports only.
• Pick Konohan 12 if you are equipping a classroom, library, testing room or kids' group.
• Pick AIAUXAI USB C if you want personal earbuds with a mic for calls and music on a USB-C phone, tablet or laptop.
The Konohan 12 is, plainly, a quantity play. You get twelve wired on-ear headphones in four colors — red, purple, gray and black, three of each — and every pair is sealed individually in its own bag. That single detail matters more than it sounds. Individually bagged headphones are hygienic and easy to hand out, store and track, which is exactly what you want when a device is going to pass through many different hands. It also means you can hand out a full color set and keep them organized by table or group.
On build, the headband is adjustable and made from ABS plastic, which keeps each pair lightweight and portable. The ear pads are soft rubber and described as sturdy and not easy to slip — a sensible choice for something that will be put on and taken off dozens of times a day. The cable runs 4 ft / 120 cm, which is a practical length for a desk or tablet setup: long enough to move a little, short enough not to tangle into a mess. The drivers are dynamic, with a 20 Hz to 20,000 Hz frequency range, and the design uses passive noise cancellation through the ear pads to block out some surrounding sound. That is the honest version of "noise cancelling" here — it is physical isolation, not electronics.
Compatibility is straightforward: a 3.5 mm jack, which covers most phones, laptops, library reading equipment and similar devices. Konohan also lists a wide range of non-classroom uses — airplanes, hospitals, gyms, hotels, tourism — which tells you the intended audience is broad and undemanding rather than audiophile.
Who should buy it: teachers, school IT staff, librarians, testing coordinators, activity leaders and anyone who needs a dozen working headphones at once without hunting for twelve separate purchases. Who should skip it: anyone who needs a USB-C connection, a microphone, or a single high-quality personal pair. If you want one nice set of buds for yourself, this is the wrong shape of product entirely.
The AIAUXAI USB C is the opposite approach: one pair, built around the modern port. It plugs in with a USB Type-C jack and is aimed at iPhone 17/16/15, the Galaxy S25/S26/S24/S23/S22 line, Pixel devices and other USB-C hardware. If your phone dropped the 3.5 mm socket, this is the category you are shopping in — no adapter required.
The feature set is genuinely useful for daily life. There is a built-in high-resolution DAC chip paired with a dynamic driver, which is the part that matters most for USB-C audio: a decent DAC is what keeps a digital connection from sounding thin and lifeless. AIAUXAI describes the result as crisp and balanced. There is also a built-in microphone and a multifunction inline remote, so you get hands-free calls, play/pause/skip and volume adjustment right on the cable — no unlocking your phone to change a track.
Portability is clearly a priority. The package includes a PU storage case and a pair of soft anti-slip ear caps, and the case is sized to hold the earphones and accessories or a cable adapter. For a bag, a commute, a flight or a workout, that is a tidy little kit rather than loose buds rolling around a pocket. AIAUXAI also lists home, travel, office meetings and kids' school among the intended uses.
The honest trade-offs: this is in-ear, so it is personal listening only — you cannot share it the way you share a classroom headphone, and it will not fit a device with only a 3.5 mm jack. It is also a single pair, so it solves one person's problem, not a room's.
Who should buy it: anyone with a USB-C phone, tablet or laptop who wants a wired backup for calls and music, plus travelers who want a case and controls on the cable. Who should skip it: teachers buying for a group, or anyone still using a 3.5 mm-only device.
• Best for a classroom or shared use → Konohan 12. Twelve pairs, four colors, individually bagged, adjustable headbands.
• Best for USB-C phones and tablets → AIAUXAI USB C. Native Type-C plug with a built-in DAC, no adapter needed.
• Best for hands-free calls → AIAUXAI USB C. Built-in mic plus inline remote for calls, playback and volume.
• Best for old-style 3.5 mm devices → Konohan 12. A standard 3.5 mm jack covers laptops, phones and library equipment.
• Best for travel and commuting → AIAUXAI USB C. Compact in-ear buds with a PU storage case and spare ear caps.
• Best for buying in bulk → Konohan 12. One purchase covers a dozen listeners.
• Best for one person who wants a tidy personal setup → AIAUXAI USB C. Case, controls and mic in a single package.
• Best for long listening sessions on-ear → Konohan 12. Over-ear rubber pads and a lightweight ABS frame.
In my opinion, the right answer depends entirely on whether you are buying for a group or for yourself. If you are outfitting a classroom, library, testing room or kids' program, I would buy the Konohan 12 — twelve color-coded, individually wrapped, adjustable 3.5 mm headphones is exactly the shape of product that job needs, and the mixed colors make distribution and storage noticeably easier. If you are one person with a USB-C phone, tablet or laptop, I would buy the AIAUXAI USB C instead: the DAC, mic, inline controls and storage case make it a complete personal kit. Neither is a compromise pick — they simply serve different buyers.
If you need multiple pairs, yes — a 12-pack with four colors and individual wrapping removes a lot of repeat purchasing and storage hassle. For a single listener, a one-pair product makes more sense. Check the current price on Amazon to compare against buying singles.
AIAUXAI lists iPhone 17, 16 and 15 among the supported devices, along with Galaxy S25/S26/S24/S23/S22 and Pixel models. It connects through the USB-C jack, so any USB-C device with audio support is the target. If your device only has a 3.5 mm port, it is not the right fit.
The Konohan 12 uses passive noise cancellation — the soft rubber on-ear pads physically block some outside sound. The AIAUXAI USB C is in-ear, and its soft anti-slip ear caps seal inside the ear canal, which typically isolates more. Neither uses active electronic noise cancelling.
Yes — Konohan specifically lists listening and testing, online lessons, libraries and classroom use, and the 4 ft cable suits a desk or tablet. The 3.5 mm jack is the thing to verify against your devices before you buy.
