How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight in-ear wired earbud with a microphone and full in-line button control for calls, classes and travel, choose ASKUBSKU Earbuds; if you need a two-pack of rugged over-ear headphones built to survive students and shared devices, choose Generic STM1BK.
• ASKUBSKU Earbuds — biggest strength: a true in-ear design with three sizes of silicone eartips, a built-in microphone and in-line buttons that handle play/pause, volume, calls and even the camera shutter.
• ASKUBSKU Earbuds — biggest trade-off: because it's an in-ear bud, it leans on sound isolation and fit rather than big over-ear drivers, and the purple finish is a look you either want or don't.
• Generic STM1BK — biggest strength: a two-pack of mid-sized over-ear headphones with 40 mm drivers, an adjustable padded headband and a braided Dura-Cord that resists chewing, kinking and knotting.
• Generic STM1BK — biggest trade-off: it's a headphone, not a headset — there's an in-line volume wheel but no microphone and no call controls in the specs.
• Who each pick is for: ASKUBSKU Earbuds for one person who wants a pocketable wired bud for calls and music; Generic STM1BK for classrooms, families or shared desks where two rugged pairs beat one delicate pair.
The ASKUBSKU Earbuds are a wired 3.5 mm in-ear pair with a semi in-ear shape that sits about 45 degrees into the ear. That angle matters more than it sounds — it's the difference between a bud that stays put when you turn your head and one that pops out on the walk to class. You get three sizes of soft silicone eartips (L, M and S) in the box, plus a replacement eartip and a protective case, so you can dial in the seal instead of accepting whatever fit the factory gave you. The enclosure mixes silicone and TPE, and ASKUBSKU describes the fit as pressure-free for long wear. I'd read that as: this is a bud you can leave in for a two-hour lecture without your ears aching.
The control story is where this pair earns its place. There's an in-line module that handles play/pause, volume up and down, answer and hang up, waking the voice assistant, and pressing the camera shutter. That last one is genuinely useful — you can shoot photos on your phone without touching the screen. The microphone is described as high-sensitivity and multi-directional, tuned for clearer voice pickup on calls. So if you take meetings from a laptop, chat on Discord, or just want to answer a call without digging your phone out of a bag, the button pod is doing real work.
Impedance is 32 ohm and the driver is a dynamic type — easy numbers for a phone, tablet, Chromebook or laptop to drive without a dongle or amp. The compatibility list is unusually broad: Samsung Galaxy phones going back several generations, Google Pixel, OnePlus, Motorola, older iPhone SE and 6-series models, iPads and iPad minis, Switch, PS4, PS5, MP3 and MP4 players, plus any Android phone, tablet, PC, laptop or Chromebook with a 3.5 mm jack. If your device still has a headphone port, this bud almost certainly plugs into it.
Buy it if you want one compact wired earbud for calls, music and travel, you like a snug in-ear seal, and you want physical buttons instead of touch controls. Skip it if you can't stand anything inside your ear canal, you need over-ear drivers for a bigger soundstage, or you need two pairs at once — this is a single set.
The Generic STM1BK is an over-ear headphone — specifically, a pack of two Smart-Trek Mini headphones. The "mini" is about sizing, not sound: the headband is adjustable and mid-sized, so it's meant to fit students and adults on the same pair. If you've ever handed a kid a pair of full-size studio cans and watched them slide off, that adjustable mid-size fit is the whole point. Over-ear placement means the cups sit around your ears rather than inside them, which is a completely different feel from an earbud.
The build is the headline. The cable is a 5-foot Dura-Cord braided cord that the spec sheet says resists chewing, kinking and knotting. Chewing is not a typo — that's a classroom reality, and it's the single most common way cheap headphones die in a school setting. The plug is a 3.5 mm angled TRS connector, and the angled shape takes stress off the joint when the cable gets yanked. The ear pads are leatherette, easy to wipe down, and provide passive noise isolation — again, a shared-use design decision.
Sound comes from 40 mm stereo drivers with a 50 Hz to 20 kHz frequency response and 32 ohm impedance. That impedance figure matches the ASKUBSKU pair, so it drives just as easily from a phone, tablet or computer. The 40 mm driver size is the meaningful difference here: bigger drivers generally move more air, which tends to give over-ear headphones more low-end presence and a wider sense of space than a small in-ear bud. At 4.48 ounces, it's light enough for extended listening sessions, and there's an in-line volume wheel so you can adjust loudness at the cable instead of reaching for the device.
One thing the specs make clear: there's no microphone listed. This is a listening headphone, not a headset. Video calls, voice chat and phone calls aren't its job. It's also noted as Prop 65 compliant and designed for educational environments, which tells you exactly who the manufacturer had in mind.
Side-by-Side: Which Should You Choose?
• Best for calls and voice chat → ASKUBSKU Earbuds. It's the only one of the two with a built-in microphone and call-answering controls in the specs.
• Best for durability against rough handling → Generic STM1BK. The chew-, kink- and knot-resistant braided Dura-Cord and angled plug are built for abuse.
• Best for classroom or multi-user setups → Generic STM1BK. It comes as a two-pack, the headband adjusts between students and adults, and the leatherette pads wipe clean.
• Best for portability → ASKUBSKU Earbuds. A small in-ear bud with a protective case disappears into a pocket; a 5-foot-cord over-ear headphone does not.
• Best for long-wear comfort if you dislike things in your ears → Generic STM1BK. Over-ear leatherette cushions and a padded headband avoid the in-canal fit entirely.
• Best for a snug, stay-put fit during movement → ASKUBSKU Earbuds. The 45-degree angled semi in-ear shape and three eartip sizes are designed to resist falling out.
• Best for bigger drivers and a wider soundstage → Generic STM1BK. 40 mm stereo drivers against a compact dynamic in-ear driver; physics favors the over-ear here.
• Best for one person who wants buttons, not touch controls → ASKUBSKU Earbuds. In-line buttons cover play, volume, calls, voice assistant and the camera shutter.
• Best if you need both a headset and a listening pair → buy both. They solve different problems, and the STM1BK already arrives as two.
For most people reading this, I'd pick the ASKUBSKU Earbuds. It does more jobs: it's a headset with a mic and full in-line controls, it's small enough to carry every day, and the three eartip sizes plus the angled fit mean you can actually get a seal instead of fighting one. The Generic STM1BK is the better answer in one specific situation — you're buying for students or a shared space and you need two rugged over-ear pairs that survive chewing, kinking and being handed around. In my opinion, if you only buy one thing and you ever take calls, the ASKUBSKU is the one that stays useful. If you need volume on a class set, go STM1BK. Either way, check the current price on Amazon before you commit — value is the last variable, and it changes.
Yes. The ASKUBSKU pair has a built-in high-sensitivity microphone and in-line controls for answering and hanging up, plus play/pause and volume. The Generic STM1BK's specs list an in-line volume wheel only — no microphone — so it isn't a call headset.
Yes, it's sold as a pack of two Smart-Trek Mini headphones. The ASKUBSKU Earbuds are a single set, though they include three sizes of silicone eartips and a protective case.
The Generic STM1BK, based on its design. The braided Dura-Cord is described as chew-, kink- and knot-resistant, the 3.5 mm plug is angled to relieve strain, and the leatherette pads are easy to clean. Those are choices aimed squarely at classroom wear and tear.
The Generic STM1BK uses 40 mm stereo drivers with a 50 Hz–20 kHz frequency response, which generally gives over-ear headphones more low-end and a wider soundstage. The ASKUBSKU Earbuds use a compact dynamic driver and rely on an in-ear seal for isolation. Both are rated at 32 ohm, so neither needs extra amplification from a phone or laptop.
