If you want a cost-effective way to equip a whole classroom, testing lab or library with wired on-ear headphones, choose TJZXGUI Bulk Headphones; if you need a single headset with a boom microphone and in-line call controls for calls, online classes or a home office, choose JIAMQISHI USB Headset. These two are built for completely different jobs, so the right pick comes down to one question: are you outfitting a group, or arming one person to talk and listen?
• TJZXGUI Bulk Headphones — biggest strength: a 30-pack of identical wired on-ear headphones with a reinforced L-shaped 3.5mm jack, so an entire class or testing room gets matched gear in one go.
• TJZXGUI Bulk Headphones — biggest trade-off: no microphone and no in-line controls, so it's for listening only.
• JIAMQISHI USB Headset — biggest strength: a unidirectional boom mic that rotates 270° for left- or right-ear wear, plus in-line volume, mic mute and speaker mute with indicator lights.
• JIAMQISHI USB Headset — biggest trade-off: it's a single headset, not a set, and it carries a higher per-unit build (foam, fabric, plastic/metal) that you're paying for one at a time.
• Who each pick is for: TJZXGUI for schools, libraries, airports and shared device carts; JIAMQISHI for one person on Zoom, Skype, a call center desk or online coursework.
The TJZXGUI Bulk Headphones are a volume play. One purchase gets you 30 wired on-ear headphones, all black, all identical. That matters more than it sounds. When a school, library or testing center needs to hand out headphones to a room of students, mismatched gear creates chaos: different fit, different feel, different failure points. A matched set keeps things simple, and it means a spare is always within arm's reach when one gets yanked off a desk.
The design is aimed squarely at shared, repeated use. Each headphone weighs just 1.69 ounces, so long sessions in a computer lab or during standardized testing won't wear on a student's ears. The earcups rotate 90 degrees, which helps them fold flat for storage and adjust to fit different head shapes. The 3.5mm jack uses an L-shaped design, a small but sensible choice: a right-angle plug takes far less leverage when someone trips over a cord or shoves a tablet into a bin, so the connector is less likely to bend or break.
On the specs side, you get 35-ohm impedance, a dynamic driver and a 20 Hz–20,000 Hz frequency range — a standard full-range listening profile. These are for audio playback, not conversation. There is no microphone, no volume buttons and no mute. They plug into tablets, phones, computers and anything else with a standard 3.5mm jack, and that's the whole story. A 1-year warranty covers the set.
Buy the TJZXGUI pack if you're a teacher, librarian, IT coordinator or testing administrator who needs to equip many seats at once with simple, durable listening headphones. Skip it if you need to be heard on a call, join a video meeting or control volume without touching your device.
The JIAMQISHI USB Headset is the opposite approach: one headset, built around talking. The centerpiece is the unidirectional boom microphone. Because it's unidirectional, it focuses on the voice directly in front of it and rejects background noise from the sides and behind — the reason this style shows up in call centers and busy open offices. The boom swings 270°, so you can wear the headset on whichever ear you prefer and still position the mic where it picks you up clearly.
Comfort gets real attention here. The headband adjusts to fit both adults and kids, and the earpads use soft protein memory foam with breathable materials. That matters for anyone wearing a headset for a full shift, a long webinar or back-to-back online classes — heat and sweat build up fast on cheap pads. The enclosure mixes foam, fabric and plastic/metal, and the color is apricot, so it's a friendlier look than plain black office gear.
The audio side uses a 40mm dynamic driver with a built-in sound card and a 20 Hz–20,000 Hz range. A bigger driver with a dedicated sound card generally means fuller bass and clearer speech than a bare 3.5mm connection, which is exactly what you want for voice calls, music and video. The 3-ohm impedance reflects that active, powered design.
Connectivity is the flexible part: it ships with both USB and 3.5mm options. The 3.5mm cable runs about 5 feet, the USB section adds roughly 4 more, and the in-line control gives you volume, microphone mute and speaker mute with indicator lights so you can see at a glance whether you're live. It's listed as compatible with PC, Mac, iOS, Android, Chromebook, tablets, MP3 players and consoles with an aux port. A lightweight drawstring bag is included for carrying it between home and office, and the warranty runs 24 months.
Buy the JIAMQISHI headset if you spend your day on calls, teach or attend online classes, or work in a call center or shared office where your voice needs to come through cleanly. Skip it if you need to equip a whole room — this is one headset, and buying thirty of them is a different budget conversation.
• Best for equipping a whole room → TJZXGUI Bulk Headphones. 30 matched units in one purchase, with a reinforced jack built for shared, careless handling.
• Best for clear voice pickup → JIAMQISHI USB Headset. The unidirectional 270° boom mic prioritizes your voice and pushes background noise down.
• Best for listening-only tasks like testing and study → TJZXGUI Bulk Headphones. No mic, no controls, nothing for a student to fiddle with.
• Best for calls and meetings → JIAMQISHI USB Headset. In-line volume, mic mute and speaker mute with indicator lights keep you in control mid-call.
• Best for long-wear comfort on the ears → JIAMQISHI USB Headset. Memory foam earpads and an adjustable headband are designed for all-day use; TJZXGUI's 1.69-ounce build is built for light, repeated sessions instead.
• Best for connection flexibility → JIAMQISHI USB Headset. USB plus 3.5mm covers desktops, laptops and phones; TJZXGUI is 3.5mm only.
• Best for durability against rough handling → TJZXGUI Bulk Headphones. The L-shaped jack is a deliberate anti-breakage design for shared classroom gear.
• Best for a single home-office setup → JIAMQISHI USB Headset. One headset, one bag, one clean desk.
If I were outfitting a classroom, library or testing center, I'd buy the TJZXGUI Bulk Headphones — 30 units, a reinforced jack and a lightweight fit solve the exact problems shared gear creates. If I were the person sitting at the desk making calls, teaching or taking online classes, I'd buy the JIAMQISHI USB Headset — the boom mic, in-line mute and memory foam pads are what you actually need when your voice is the point. These aren't competitors so much as two answers to two different questions. Pick the one that matches your room, not your mood. And before either, check the current price on Amazon, since both change with the season.
No. They have no microphone and no in-line controls, so they're for listening only. If Zoom, Skype or online classes are the goal, the JIAMQISHI USB Headset is the right tool.
Yes. It includes both USB and 3.5mm connections and is listed as compatible with PC, Mac, iOS, Android, Chromebook, tablets and consoles with an aux port.
The listing is a 30-pack of identical black wired on-ear headphones, each weighing 1.69 ounces with a 3.5mm L-shaped jack and a 1-year warranty.
The JIAMQISHI headset's unidirectional boom mic is designed to reject background noise on your end of the call, which is a different job from passive isolation. Neither listing makes isolation claims, so treat noise blocking as a microphone-side benefit on JIAMQISHI, not a listening one.
