If you want a single wired headset with a flexible noise-reducing boom mic, in-line volume control and a one-year warranty for everyday school, office or gaming use, choose KLOJIM L02; if you need a six-pack of cheap classroom headphones to hand out to a whole group of students, choose Gaosen Classroom Headphones Bulk.
• KLOJIM L02 — biggest strength: a rotatable noise-reducing microphone that swings up to 120°, plus in-line volume control, so it actually works as a talk-and-listen headset rather than just a listener.
• KLOJIM L02 — biggest trade-off: it's one headset, not a set, and it's wired 3.5mm only — dual-port PCs need a splitter you supply yourself.
• Gaosen Classroom Headphones Bulk — biggest strength: six pairs in one box in mixed colors, with thicker cords and a 4 ft cable that reaches across a desk to a Chromebook or tablet.
• Gaosen Classroom Headphones Bulk — biggest trade-off: no microphone, so it's for listening and studying, not for talking back on a call.
• Pick KLOJIM L02 if you're one person who needs a mic and volume control; pick Gaosen if you're equipping a room.
The L02 is built around one idea: be a workhorse headset for a single user. The standout spec is the microphone. It rotates up to 120° so you can park it where your mouth actually is, and it's a noise-reducing boom, which matters if you're on calls in a room that isn't quiet. That alone separates it from a plain pair of listening headphones — many cheap sets in this category don't have a mic at all, and the ones that do often have a fixed stub you can't position.
Comfort is handled with an adjustable headband and memory foam ear cushions wrapped in protein leather, and the on-ear design keeps it light enough to wear through a long class or a shift. The in-line volume control is a small thing that turns out to be a big thing in practice: you adjust loudness at the cord instead of alt-tabbing into your device's audio settings every time a video is too loud. It's wired 3.5mm, so there's no pairing, no charging and no battery to die mid-lesson.
Who should buy it: a student, remote worker, call-center person or gamer who needs one headset that does voice and audio, and who wants a mic they can aim. Who should skip it: anyone buying for a whole classroom, or anyone on a dual-port desktop PC who doesn't want to buy a splitter — the mic needs one there, and it isn't included.
Gaosen Classroom Headphones Bulk: Who It's For
The Gaosen set is a different product with a different job. You get six on-ear headphones in mixed colors, individually bagged, with a model number of GS857. The whole point is volume: one purchase outfits a group, and the colors make it easy to hand them out and get them back without arguments.
The build is aimed at exactly that abuse. The cord is upgraded and thicker for durability, the frames are described as lightweight and bendable, and the ear cups swivel — all things that matter when thirty kids are pulling headphones on and off. The cable is 4 ft with a stereo 3.5mm plug, which reaches comfortably from a child's seat to an iPad, Chromebook, laptop, tablet or PC. Impedance is 32 ohm, which is an easy load for the headphone outputs on those devices.
Audio is handled by 40mm drivers with a 20Hz–20,000Hz range, tuned for balanced, clear sound. Soft foam ear pads and an adjustable headband cover both kids and adults. There's a media control and no noise cancelling. Critically, there's no microphone — this is a listen-only headphone, so it's for lessons, videos, audiobooks and quiet study, not for speaking.
The brand also positions these as disposable-style headphones for hospitals, hotels, museums, gyms and libraries — anywhere you need to hand someone a pair and not worry about it. It carries a one-year manufacturer warranty.
Who should buy it: teachers, schools, librarians, trainers and anyone setting up a shared listening station. Who should skip it: a single user who needs to talk on calls, and anyone who wants a mic — you won't find one here.
• Best for voice calls and online classes → KLOJIM L02, because it's the only one of the two with a microphone.
• Best for equipping a group → Gaosen Classroom Headphones Bulk, since six pairs ship in one box.
• Best for adjustable mic positioning → KLOJIM L02, with its 120° rotatable boom.
• Best for cable reach at a desk → Gaosen, with a 4 ft cord versus a shorter, tangle-resistant one on the L02.
• Best for controlling loudness without touching your device → KLOJIM L02, thanks to in-line volume control.
• Best for shared or high-turnover environments → Gaosen, with thicker cords, bendable frames and swivel cups.
• Best for a single all-rounder → KLOJIM L02, because it covers listening and talking in one unit.
• Best if you don't want to buy a splitter → Gaosen, since it's pure output and has no mic to route.
For one person who needs to be heard, I'd buy the KLOJIM L02. The rotatable noise-reducing mic and in-line volume control are the two features that make a cheap wired headset genuinely usable for classes, calls and gaming, and the one-year warranty and reinforced cable signal it's meant to last. I'd only steer you to the Gaosen set if the number of listeners, not the features, is the whole problem — six pairs in mixed colors is the practical answer for a classroom, and no single headset solves that. If you're price-sensitive either way, check the current price on Amazon before deciding, since that's the one thing that can tip a close call.
how to make cheap headphones sound better
Start with fit and source. The KLOJIM L02's memory foam on-ear cushions and adjustable headband let you seat the drivers properly, which tightens bass and clarity more than any setting. On the Gaosen set, make sure the 3.5mm plug is fully seated and the device volume is up — beyond that, both are wired 20Hz–20kHz designs with no EQ built in, so adjust from your device.
how to get cheap headphones
The cheapest route is usually buying in bulk rather than one at a time. The Gaosen Classroom Headphones Bulk ships as a six-pack of GS857 on-ear headphones, which spreads the cost across six listeners. If you only need one, the KLOJIM L02 is a single-unit wired headset with a mic, so you're paying for features rather than quantity. Check the current price on Amazon for both.
how to pair cheap headphones
You don't pair either of these. Both are wired 3.5mm headphones — the KLOJIM L02 and the Gaosen GS857 plug straight into a phone, tablet, laptop, Chromebook or PC. "Pairing" only applies to Bluetooth, and neither product uses it. Just plug in and set your volume.
what is the cheapest headphones
There's no fixed answer, because it changes constantly with sellers and pack sizes. What I can tell you is the shape of the choice: a multi-pack like the Gaosen six-pack lowers the cost per pair, while a single headset like the KLOJIM L02 costs more per unit but adds a microphone, in-line volume control and a one-year warranty. Compare the current prices on Amazon for the real numbers.
