If you want a large batch of simple wired earbuds you can hand out to a group — especially for computer use in classrooms, labs or libraries — choose TFD Supplies Wholesale Bulk Earbuds; if you need one durable, sporty USB-C pair for a single Android phone or laptop, choose iMangoo USB C Headphones. That's the whole decision in one line. Everything below is me working through the specifics so you can match the pick to your actual situation.
• TFD Supplies biggest strength: You get 100 individually bagged earbuds in one go, each with a standard 3.5mm jack that fits iPhone, Android, MP3 players, Chromebooks and laptops — ideal when many people need to plug in and listen.
• TFD Supplies biggest trade-off: It's a bulk supply, not a personal audio product. Random mixed colors, a basic wired in-ear design, no USB-C option and no microphone or remote.
• iMangoo biggest strength: A single USB-C pair built for movement — over-ear ear hooks, three sizes of silicone tips, a built-in DAC chip, an in-line remote with microphone, and a tangle-free reinforced cord.
• iMangoo biggest trade-off: It's one pair for one USB-C device. No 3.5mm jack, so older phones and gear with a headphone port simply won't work.
• Who TFD Supplies is for: Teachers, school tech staff, event organizers and anyone equipping a room of computers with shared listening.
• Who iMangoo is for: One Android phone owner who wants a secure, gym-ready USB-C earbud with call controls.
Think of this as infrastructure, not a personal gadget. The listing is 100 earbuds, individually bagged inside a larger bag, in a random mix drawn from twelve color options. Every pair uses a standard 3.5mm stereo jack, which is the connector that still shows up on the widest range of audio gear — tablets, iPads, Chromebooks, laptops, desktops and music players. The brand positions the whole line around schools, libraries, museums and promotional handouts, and it's sold in different quantities and packaging if 100 isn't the right number for you.
For a computer-focused buyer, that's the real selling point. If you're setting up a row of desktops or a cart of Chromebooks and you need a rechargeable in ear earbuds for computer setup without hunting for chargers, the wired 3.5mm design sidesteps the whole battery problem — nothing to charge, nothing to pair, nothing to lose track of. You hand one to each student or visitor and they're listening in seconds. The 20Hz–20kHz frequency range and 32-ohm impedance are standard, broadly compatible figures that most devices drive without fuss.
Who should skip it? Anyone buying for themselves. The colors are random, the fit is a plain in-ear shape, and there's no microphone or in-line remote for calls. If you want one pair that matches your phone's USB-C port or that you can take running, this isn't that product. It's a case of 100 for a crowd, and it only makes sense if you actually have a crowd.
This is the opposite philosophy: one pair, built around a single person and a single connector. The headline feature is the over-ear ear hook design — the earbuds sit in your ear while a hook loops over the top, which is what keeps them stable during a run, a jog or a workout. iMangoo ships three sizes of silicone ear tips so you can dial in the fit, and the hook shape is the reason this reads as sport gear rather than a commuter earbud.
The USB-C connection is the other half of the story, and the compatibility list is genuinely long: iPhone 15 through 17 family and iPhone Air, a wide spread of Samsung Galaxy S, Note, Z Fold and Z Flip models, iPads, MacBook Air and Pro, Google Pixel, OnePlus and Motorola USB-C devices. There's a built-in DAC chip to keep the audio clean, and the company calls out the absence of buzzing and popping as a design goal. Controls live on the cord — a remote with volume buttons and a microphone for answering and ending calls, plus play/pause and track skipping.
Build-wise, the connectors are metal-plated to resist poor contact, the cord is TPE and described as tangle-free, and it's rated to survive a 5000+ bend test — a durability claim aimed at daily use. Sound isolation, rather than active noise cancellation, is what you get here. It weighs 40 grams and comes with a protective case. The main limitation is obvious: no 3.5mm jack. If your device doesn't have USB-C, this pair is a non-starter, and the manufacturer lists an 8-month warranty.
Side-by-Side: Which Should You Choose?
• Best for equipping a group or a computer lab → TFD Supplies Wholesale Bulk Earbuds. 100 pairs, individually bagged, ready to distribute.
• Best for workouts, running and gym use → iMangoo USB C Headphones. The over-ear hooks and three tip sizes are designed exactly for that.
• Best for older devices and mixed hardware → TFD Supplies Wholesale Bulk Earbuds. The 3.5mm jack fits the broadest range of audio gear.
• Best for hands-free calls → iMangoo USB C Headphones. TFD's earbuds have no microphone.
• Best for zero-maintenance listening → TFD Supplies Wholesale Bulk Earbuds. Wired 3.5mm means no pairing, no charging, no setup.
• Best for a single durable pair with a case → iMangoo USB C Headphones. Reinforced cord, metal-plated connectors, protective case included.
• Best for shared or promotional use → TFD Supplies Wholesale Bulk Earbuds. The brand explicitly builds this line for schools, libraries and giveaways.
For most people reading this for themselves — one person, one Android phone, wanting earbuds that stay put and let them take calls — I'd buy the iMangoo USB C Headphones. The combination of ear hooks, USB-C with a DAC chip, an in-line remote, a microphone and a reinforced cord is simply the more useful package for personal daily use, and it works for computer duty too if your laptop has USB-C. I'd only choose the TFD Supplies Wholesale Bulk Earbuds if my goal were outfitting many people at once — a classroom, a lab, a cart of computers — where 100 individually bagged 3.5mm earbuds solve a logistics problem no single pair can. Buy the iMangoo for yourself; buy the TFD case when you're buying for a room.
how to connect headphones android
With the iMangoo pair there's nothing to pair — it's wired USB-C, so you plug it into the port and audio routes through automatically, assuming your phone has USB-C. The TFD Supplies earbuds are wired 3.5mm, so they need a headphone jack or a USB-C-to-3.5mm adapter. Both are plug-and-play once the connector matches.
how to find headphones android
Start with the connector, not the brand. Check whether your Android phone has a 3.5mm jack or only USB-C — that single fact decides which of these two products can even work for you. Then match the fit to your use: plain in-ear for casual listening, over-ear hooks if you'll be moving around.

For these two products, pairing doesn't apply — both are wired, so there's no Bluetooth menu involved. You connect by plugging in, and volume and playback controls on the iMangoo run through its in-line remote. If you specifically want a bluetooth headband headphones for computer setup instead, that's a different category altogether and neither of these is it.
how to eq headphones android
Android's sound settings and most music apps include an equalizer you can adjust once the earbuds are plugged in. Both products list a 20Hz–20kHz range and 32-ohm impedance, so they respond to normal EQ tweaks; the iMangoo's built-in DAC chip is designed to keep that signal clean. Small adjustments go further than extreme ones on either pair.
