If you want a bulk set of on-ear wired headphones that keeps volume control simple and works with just about any 3.5mm device, choose Bulktech 10; if you need a single pair of USB-C in-ear earbuds with a mic, in-line volume control and a pocketable case for a modern phone, choose ACANDYA USB C Earbuds. That's the short version — and for college students juggling a laptop, a phone and a shared dorm room, the right answer really does split along that line.
• Bulktech 10 biggest strength: Ten pairs of on-ear leather headphones with a 3.5mm jack and a remote that handles volume — one purchase that covers a whole household, classroom or study group.
• Bulktech 10 biggest trade-off: It's an analog 3.5mm set with no microphone and no active noise control, so it won't plug into a phone or tablet that has dropped the headphone jack.
• ACANDYA USB C Earbuds biggest strength: A USB-C connection with an inline mic and remote for calls, track skipping and volume, plus three ear tip sizes and a storage case in a package that weighs almost nothing.
• ACANDYA USB C Earbuds biggest trade-off: It's one pair of in-ear buds, and it only fits USB-C ports — anything with a 3.5mm socket is out of the question.
• Who Bulktech 10 is for: Buyers who need several pairs at once and want them to work across older and newer gear with a headphone jack.
• Who ACANDYA USB C Earbuds is for: One person with a modern USB-C phone, tablet or laptop who wants a light, portable set with a microphone.
Bulktech 10 is built around a very specific idea: a big bundle of wired on-ear headphones that all share the same 3.5mm plug and the same volume remote. The set ships as ten black leather on-ear units, each with a 5-foot cable, a 32-ohm impedance and a dynamic driver rated for a 20–100 frequency range. That 32-ohm figure matters in practice — it's a low-impedance load, which is the kind of spec that tends to play nicely with phones, tablets, Chromebooks and PCs straight out of the jack, no amp required.
The design leans hard into comfort and durability. The build is lightweight and adjustable, the ear cushions are soft, and the cups swivel so the whole thing stacks and stores flat. Bulktech also points out the thick wire and extra-durable materials, which is the part that makes sense for the audience this set clearly targets: kids and adults sharing hardware. The brand lists classrooms, libraries, computer labs, museums, health centers, kindergartens, remote learning and travel as intended settings. Read that list again and it tells you everything — this is a "hand one to everybody" product, not a personal flagship.
Who should buy it? Anyone who needs multiple pairs and doesn't want to think about pairing, charging or Bluetooth. A household with several kids, a tutor running small sessions, a dorm floor that keeps losing earbuds — the ten-pack solves a logistics problem more than it solves an audiophile one. In my opinion, it's the pick for the best over ear headphones for college students who want something they can pass around and not panic about.
Who should skip it? If your primary device is a newer phone or tablet with only a USB-C port, this set can't reach it. There's also no microphone and no noise control, so it's not the tool for online meetings or noisy commutes where you need to block sound or talk hands-free.
ACANDYA USB C Earbuds go the opposite direction: one small, focused product for one person. These are USB-C wired in-ear buds with an aluminum and TPE build, a 1.2m cable, an inline microphone and a button remote that handles song switching and volume. They're rated at the same 32-ohm impedance as the Bulktech set, but with a full 20 Hz – 20,000 Hz frequency range and a DAC chip onboard — the DAC is the piece that matters here, because plenty of USB-C audio gear skips it and leaves you with a flat, quiet signal. Having it built in is a genuine plus.
The fit story is thought through. You get an ergonomic in-ear design with three ear tip sizes, medium pre-installed, and the seal those tips create is what delivers the sound isolation ACANDYA advertises. The whole package weighs about 0.03 kg and comes with a small protective case, so it disappears into a pocket or a backpack front pouch. The theme list — video game, music, sports — hints at how the brand expects these to be used, and the emphasis on bass and immersive audio lines up with gaming and streaming more than critical listening.
Compatibility is where these shine and where they narrow. The list covers iPhone 15/16/17 family, iPad 10th gen, iPad Air and Pro, MacBook Pro, Galaxy S24/S25/S26 and Tab S9, Google Pixel 7 through 10, OnePlus, Motorola Edge and Razr models — basically any USB-C device with no 3.5mm port. I recommend these for the best in ear earbuds for college students who carry a USB-C phone or tablet all day and want calls plus music from one cable.
Skip them if you own anything with a round 3.5mm socket, if you prefer over-ear cups, or if you want a set you can share with a roommate — there's exactly one pair here.
• Best for volume control on a budget bundle → Bulktech 10. The remote handles volume on every one of the ten pairs, and it's the same control on each.
• Best for hands-free calls → ACANDYA USB C Earbuds. The inline mic and button remote are built for answering calls and switching tracks without touching your phone.
• Best for portability → ACANDYA USB C Earbuds. At roughly 0.03 kg with a storage case, they're the pair that actually lives in your pocket.
• Best for sharing or classroom use → Bulktech 10. Ten units, swivel cups, thick wiring and a kid-and-adult fit range make it a hand-out set.
• Best for gaming → ACANDYA USB C Earbuds. The DAC chip, 20 Hz – 20,000 Hz range and bass-forward tuning suit the best gaming headphones for college students who game on a USB-C device.
• Best for older gear → Bulktech 10. The 3.5mm jack reaches tablets, PCs, Chromebooks and anything with a standard headphone socket.
• Best for noisy rooms → ACANDYA USB C Earbuds. The in-ear seal with three tip sizes gives real sound isolation; the Bulktech set has no noise control at all.
• Best for a mixed household with several users → Bulktech 10, while a single USB-C user should go the other way.
If I had to pick one, I'd buy the ACANDYA USB C Earbuds — for a college student on a USB-C phone or laptop, the mic, the click-control volume remote, the DAC chip and the tiny case cover more of a normal day than ten pairs of on-ear headphones ever could. That said, my opinion flips if your priority is outfitting several people at once or you're still on 3.5mm hardware: then the Bulktech 10 is the smarter buy, and the volume remote on every pair is the feature you'll actually use. Check the current price on Amazon for whichever fits your devices, then decide.
how to disable volume control on wired headphones
On most wired sets the volume control is a passive in-line wheel or button, and there's no software switch to turn it off. If your headphones have a physical remote like these two, the only practical option is to set volume on the device itself and leave the remote at maximum, or use a headphone model that has no in-line control at all.
do earbuds have volume control
Many do, and the ACANDYA USB C Earbuds are an example — they include an inline remote with volume adjustment and track switching. The Bulktech 10 on-ear set also has a remote control for volume. Whether you get that feature depends entirely on the specific model, not on the earbud versus headphone category.
It's the port, not the sound. Bulktech 10 uses a 3.5mm jack, so it fits tablets, PCs, Chromebooks and older phones. The ACANDYA set uses USB-C, which suits iPhone 15/16/17, recent iPad, Galaxy, Pixel and MacBook models that lack a headphone socket. Pick based on the port your device actually has.
For calls, yes — there's an inline microphone and remote for hands-free use. For gaming, the DAC chip, 20 Hz – 20,000 Hz range and bass emphasis make them a reasonable USB-C choice, and the in-ear seal helps isolate background noise. The Bulktech 10 has no mic, so it's not the one for voice chat.
