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 wired headset you can actually talk into — with a rotatable noise-reducing mic and in-line volume control for one user — choose KLOJIM L02; if you need a ready-to-hand-out class set of ten basic 3.5mm headphones for a classroom, testing room or school cart, choose MENGLALA Kids Headphones Bulk.
• KLOJIM L02 — biggest strength: A rotatable noise-reducing boom mic plus in-line volume controls make it a real two-way headset for online classes, calls and gaming, not just a listening device.
• KLOJIM L02 — biggest trade-off: It's a single headset (one per box), so it can't equip a whole classroom, and dual-port PCs need a splitter that isn't included to use the mic.
• MENGLALA Kids Headphones Bulk — biggest strength: It arrives as a 10-pack of on-ear headphones with a ruggedized 3.5mm plug, which is exactly what you want when you're outfitting a group at once.
• MENGLALA Kids Headphones Bulk — biggest trade-off: There's no microphone and no volume control on the cable, so it's for listening, not speaking — no calls, no voice recording, no test responses spoken aloud.
• Who each pick is for: KLOJIM L02 for one student, remote worker or gamer who needs to talk and listen; MENGLALA Kids Headphones Bulk for a teacher, school or program buying for many kids at the same time.
KLOJIM L02 is built around communication. The stereo drivers cover a 20Hz–20kHz range with what the spec sheet describes as balanced bass and clear highs, and the microphone rotates up to 120° so you can park it near your mouth for a call and swing it out of the way when you're just listening. The mic is designed to reduce background noise, which matters in a house with other people in it. In-line volume controls sit on the cable, so you adjust loudness without reaching for the laptop or phone.
The fit is deliberately broad. An extra-padded adjustable headband and memory foam ear cushions wrapped in protein leather are meant to suit kids ages 4 and up, teens and adults — so it's a headset a family can share across ages, or one person can wear through a long school day or work shift. The 3.5mm jack plugs into smartphones, computers, laptops and MP3/MP4 players. The one caveat worth flagging: on desktop PCs with separate headphone and mic ports, you'll need a splitter (not included) to get the microphone working. The reinforced, tangle-resistant cable and flexible mic boom are aimed at daily wear, and it's covered by a 1-year warranty.
Buy KLOJIM L02 if you want one headset that does both jobs — listening and speaking — for online classes, remote work, call-center-style use or gaming. Skip it if your goal is outfitting a group, or if you mainly need headphones for a child who only watches and listens and never talks into a mic.
MENGLALA Kids Headphones Bulk is a classroom logistics product first and a listening product second. It ships as a 10-pack, in mixed colors, which is the whole point: you buy once and hand them out. The on-ear design uses leather ear covers that the spec sheet describes as soft and comfy, and the adjustable headband is meant to fit a range of head shapes — so the same box works across a mixed-age group of kids, teens and adults.
The plug is the detail I'd pay attention to. MENGLALA says it upgraded to a ruggedized 3.5mm plug, and that's the part that actually fails on cheap classroom headphones — kids yank cables, drop them on the floor and shove them into bags. A reinforced plug is the right place to spend the money. Compatibility is broad: tablets, iPads, Chromebooks, Switches, laptops and anything else with a 3.5mm jack. The 32-ohm impedance and 20Hz–20,000Hz range are standard, easy-to-drive numbers, which means they'll play at normal volume off a Chromebook or tablet without a headphone amp. There's no microphone and no in-line volume control, and it's a wired-only design covered by a 1-year warranty.
Buy MENGLALA Kids Headphones Bulk if you're a teacher, tutor, tester or program coordinator who needs ten pairs ready to go for a class set, a testing session, a computer lab or a school lending cart. Skip it if you need to speak into a mic, if you need per-user volume control on the cable, or if you only need one pair for one person — a 10-pack is simply more headphones than that job requires.
• Best for two-way communication (calls, online classes with talking, gaming chat) → KLOJIM L02. It's the only one of the two with a microphone, and the boom rotates up to 120°.
• Best for equipping a group at once → MENGLALA Kids Headphones Bulk. Ten pairs in one box, mixed colors, ready to distribute.
• Best for a single user who wants on-cable volume control → KLOJIM L02. In-line volume adjustment is part of the design; the MENGLALA set has no cable controls.
• Best for classroom, testing and computer-lab logistics → MENGLALA Kids Headphones Bulk. The ruggedized 3.5mm plug and broad device compatibility are aimed squarely at that environment.
• Best for mixed-age comfort in one product → a tie, with a caveat. KLOJIM L02 uses memory foam and protein leather with an adjustable headband; MENGLALA uses soft leather ear covers with an adjustable headband. Both claim to fit kids through adults, but KLOJIM's padding description is more detailed.
• Best for plug-and-play on phones, laptops and tablets → both. Both are wired 3.5mm designs with the same 20Hz–20kHz frequency range.
• Best for use with a dual-port desktop PC → KLOJIM L02, with one extra part. You'll need a splitter (not included) to get its mic working on a PC with separate mic and headphone jacks.
• Best for durability against kids' handling → MENGLALA Kids Headphones Bulk. The reinforced plug is the specific weak point it was designed to survive, which is what bulk classroom sets live or die on.
My Verdict
For one user who needs a microphone, yes — KLOJIM L02 has a rotatable noise-reducing mic and in-line volume control, and MENGLALA's set has neither. For outfitting a group of ten, MENGLALA is the better fit because KLOJIM L02 is sold as a single headset. It's a use-case difference, not a quality ranking.
No. The MENGLALA Kids Headphones Bulk spec sheet lists no microphone and no noise control — it's a listening headset with a 3.5mm plug. If you need students to speak into a mic, the KLOJIM L02 is the one to pick.
It works with any device that has a 3.5mm audio jack, including laptops, phones and tablets. On a desktop PC with separate headphone and microphone ports, you'll need a splitter (not included) for the mic to work.
Count the users. One student who talks in class → KLOJIM L02. A whole class, a testing session or a lending cart → MENGLALA Kids Headphones Bulk, since you get ten pairs in mixed colors with a ruggedized plug. If budget is the deciding factor, check the current price on Amazon for each before you commit.
