How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a single, lightweight on-ear headphone with a 40mm driver, a foldable frame and a long 1.5 m cord for one student, choose ELECDER i45; if you need a ready-to-deploy set of ten durable classroom headphones with swivel cups for a whole class, choose MUMSTHT Classroom Headphones Bulk.
• ELECDER i45 — biggest strength: A 40mm dynamic driver with a 20 Hz–20,000 Hz range, a foldable, adjustable on-ear frame and a long 1.5 m cable — a tidy single-user headphone for one kid, one Chromebook, one backpack.
• ELECDER i45 — biggest trade-off: It's one unit, not a set, so it doesn't solve the "thirty students, thirty headphones" problem, and there are no on-board volume buttons — you control volume from the device.
• MUMSTHT Classroom Headphones Bulk — biggest strength: A 10-pack, individually packaged and sealed, with swivel cups, reinforced materials, a thick cable and a bendable construction — built for shared, repeated, everyday classroom wear.
• MUMSTHT Classroom Headphones Bulk — biggest trade-off: The cord is 4 ft / 120 cm, shorter than the ELECDER's 1.5 m, so students who like to lean back or stand up while listening may feel tethered.
• Who each is for: ELECDER i45 → one student, one device, one headphone that folds away. MUMSTHT Classroom Headphones Bulk → a teacher, school, library or lab that needs a full class set at once.
The ELECDER i45 is a wired on-ear headphone built around a 40mm dynamic driver with a 20 Hz–20,000 Hz frequency range and 95 dB sensitivity. In plain terms, that's a design aimed at everyday listening — enough bass to make videos and music feel full, with a midrange that keeps speech intelligible. ELECDER describes it as Hi-Fi stereo with moderate bass and crisp midrange, plus sound isolation to take the edge off background noise. That's a sensible target for a school headphone: clear voices first, not a bass cannon.
The physical design is where it earns its place. It's an on-ear model with padded ear cushions and a padded headband, an adjustable size slider, and a foldable frame that collapses to roughly 6 × 4.53 × 2.87 inches. It weighs about 0.28 kg. The cable is 1.5 m and terminates in a standard 3.5mm plug, so it works with smartphones, Chromebooks, computers, PCs, tablets, Kindle and MP3 players. ELECDER notes that iPhone 7, iPad Pro 11 and newer need a separate Lightning-to-3.5mm adapter, which isn't included — worth knowing before you buy for an iPad-heavy household.
Who should buy it? In my opinion, this is the right pick for one student who needs a personal headphone for remote classes, homework, flights and car rides — someone who'll actually fold it up and toss it in a bag. The nylon-and-plastic build and the 12-month warranty back that up. Who should skip it? Anyone outfitting a classroom, a lab or a testing room. One headphone can't cover a room, and there are no volume controls on the ear cups — you adjust everything from the device. Also skip it if your kid is under about 8; ELECDER recommends it for kids over 8, though the adjustable band does fit a range of head sizes, adults included.
The MUMSTHT Classroom Headphones Bulk is a 10-pack of wired on-ear headphones, each individually packaged and sealed. That single detail tells you what it's for: handing out, collecting, storing, repeating — day after day, term after term. Each unit uses a dynamic driver with a 20 Hz–20,000 Hz frequency range, 32 ohm impedance and 92 dB sensitivity. The frequency response is listed as 20.4 KHz at the top end, effectively the same 20 kHz ceiling as the ELECDER. Low impedance plus modest sensitivity means these are easy to drive from a Chromebook, laptop, tablet or phone without a headphone amp.
The build is the real story. MUMSTHT emphasizes reinforced materials, a thick, long-lasting cable and a bendable construction — the kind of decisions that matter when twenty pairs of hands are involved. The ear cups swivel, which does two things: it makes them more comfortable for different head shapes, and it lets you stack and store them flat in a bin or cabinet. Ear cushions are soft, the headband is lightweight and adjustable, and the size range is listed for kids, teens and adults. The cable is 4 ft / 120 cm with an L-shaped 3.5mm plug — the right-angle plug is a small but genuinely useful classroom detail, since straight plugs get bent when a laptop sits on a desk edge.
The intended use list is broad and honest about it: schools, libraries, classroom labs, student exams, plus hospitals, hotels, museums and gyms. The 10-piece pack (and a 5-piece option) is the point — one purchase, one consistent set, no mismatched leftovers. A one-year replacement policy and 24-hour reply commitment round it out.
Who should buy it? Teachers, IT coordinators, librarians, testing administrators, and anyone who needs a standard-issue set of student headphones that can survive a room full of kids. Who should skip it? A single student who just needs one pair. Buying ten to use one is wasteful, and the shorter 120 cm cable is less convenient for individual travel or airplane use than a longer cord.
• Best for one student, one device → ELECDER i45. One headphone, one 1.5 m cable, one foldable frame for a backpack.
• Best for a whole class at once → MUMSTHT Classroom Headphones Bulk. Ten individually sealed units, ready to distribute and store.
• Best for long cable reach → ELECDER i45. 1.5 m beats the MUMSTHT's 4 ft / 120 cm when a student wants to move around at a desk.
• Best for shared, repeated handling → MUMSTHT Classroom Headphones Bulk. Reinforced materials, a thick cable, bendable construction and swivel cups made for frequent student use.
• Best for storage and stacking → MUMSTHT Classroom Headphones Bulk. Swivel cups stack flat; the ELECDER folds, but it's one unit, not a set.
• Best for travel and portability → ELECDER i45. Folds to roughly 6 × 4.53 × 2.87 inches and slips into a bag or carry-on.
• Best for plugging into a laptop on a desk edge → MUMSTHT Classroom Headphones Bulk. The L-shaped 3.5mm plug resists the bending that straight plugs suffer.
• Best for an iPad Pro 11 or newer → neither, without an adapter. Both are 3.5mm wired; those iPads need a separate Lightning-to-3.5mm adapter.
• Best for audio spec parity → a tie on range. Both list 20 Hz–20,000 Hz; the ELECDER pairs a 40mm driver with 95 dB sensitivity, the MUMSTHT uses 32 ohm impedance and 92 dB.
If I were buying for one child to use at home, on the bus and on flights, I'd pick the ELECDER i45 — the 40mm driver, the 1.5 m cord, the foldable frame and the padded on-ear fit make it the better personal headphone, and it's the one that won't get lost in a classroom bin.
If I were equipping a classroom, library or testing room, I'd buy the MUMSTHT Classroom Headphones Bulk without hesitating. Ten sealed units, swivel cups for stacking, reinforced construction and an L-shaped plug are exactly what shared student gear needs. In my opinion, buying ten individual headphones for a class is the wrong move — the bulk pack exists precisely for that job.
FAQ
Yes. Both use a standard 3.5mm wired jack and are listed as compatible with Chromebooks, laptops, PCs, tablets and phones. The one exception: iPhone 7, iPad Pro 11 and newer need a Lightning-to-3.5mm adapter, which is not included with either.
By design, the MUMSTHT bulk pack leans hardest into durability — reinforced materials, a thick cable, bendable construction and swivel cups aimed at frequent student use. The ELECDER i45 is a lightweight, foldable personal headphone with a 12-month warranty, better suited to one careful owner.
Neither is described as having on-board volume buttons. The ELECDER i45 lists media control with a wired controller, and volume is adjusted from the device. If you need a mic for online classes, check your device's own mic, since neither data sheet lists a built-in microphone.
