How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired on-ear set that plugs straight into USB-C school devices and comes as a colour-coded five-pack, choose YFSFQS USB Type C; if you need a bigger, cheaper-per-unit pile of classic 3.5 mm in-ear buds for a mixed-age classroom, choose Oidroy Bulk.
• YFSFQS USB Type C — biggest strength: native USB-C connection with no adapter needed, plus a five-colour set that makes it obvious whose pair is whose in a shared classroom.
• YFSFQS USB Type C — biggest trade-off: it is an on-ear design with no noise control and a fixed cable, so it takes up more room and won't fold away flat.
• Oidroy Bulk — biggest strength: ten pairs in one box, a lightweight 3 g in-ear fit, a 4 ft tensile PVC cord built for repeated shared use, and passive noise cancellation.
• Oidroy Bulk — biggest trade-off: it uses a 3.5 mm plug, so it won't connect to USB-C-only tablets, laptops or phones without an adapter.
• Who YFSFQS USB Type C is for: teens and students on USB-C school devices who need on-ear comfort and colour-based identification.
• Who Oidroy Bulk is for: teachers, parents and programme organisers stocking a large mixed-age group that still uses 3.5 mm headphone jacks.
YFSFQS USB Type C solves one very specific classroom problem: the device you hand a student has a USB-C port and nothing else. No dongle, no adapter, no "where did the little connector go" five minutes at the start of a lesson. You plug the cable in and it works. That single feature is the reason this set exists, and it is the reason I'd point a teacher with a USB-C fleet straight at it.
The second thing this set gets right is the five-colour group design. Red, green, light blue, purple and rose red — one colour per student. In a shared lab or a testing session where pairs get handed out and collected back, colour coding cuts down on mix-ups and arguments about whose headphones are whose. It sounds trivial until you have run a room of thirty teenagers. The on-ear pads and adjustable headband cover a range of head sizes, and the spec lists the age range as kid, teen and adult, so a set like this can move between year groups without anyone feeling like they're wearing a toy. Impedance is 32 ohm, which is the ordinary, easy-to-drive figure you want for laptops, tablets and Chromebook-style school hardware.
The single-cord design is the quiet practical win: fewer tangles, faster storage, less time untangling a box of thirty at the end of a lesson. The build is described as sturdy with soft ear pads, and it carries a one-year warranty. Specific uses listed include school, listening, travel and exercising.
Oidroy Bulk: Who It's For
Oidroy Bulk goes the other way: it is a volume play. Ten pairs in a single bulk package, in assorted colours, at the lightest possible weight — 3 g per earbud set. If your job is to make sure every child in a room has something to listen with, ten pairs in one box is a very different proposition from five.
The engineering choices here are all about surviving shared use. The cable is a 4 ft tough tensile PVC cord with a solid 3.5 mm plug, and the spec explicitly frames it as preventing breakage and supporting repeated student shared use. That is the honest description of what kills cheap classroom earbuds: the plug joint and the cable, not the drivers. The in-ear design with plastic enclosure and a small plastic carry case keeps each pair tidy. The listed age range is children aged three and up, and the title spans children, toddlers, teens, boys and girls — so this is a genuinely broad-age multipack rather than a teen-specific product.
On the audio side you get a 9 mm dynamic driver, 32 ohm impedance, 20 Hz frequency response, 95 sensitivity and 20 ms latency, with passive noise cancellation. That last point matters in a loud classroom: an in-ear seal blocks some surrounding chatter in a way an on-ear pad does not. The cord also carries an inline push-button remote, which is worth knowing because it is a concrete difference from the YFSFQS set, which lists no controls at all.
Who should skip it? Anyone with USB-C-only devices — the 3.5 mm jack is a hard limit here, and there is no USB-C variant in the data. Also skip it if you want over-head fit or larger drivers; this is a lightweight in-ear product by design, and that is the trade-off you accept for the low weight and the bulk quantity.
Side-by-Side: Which Should You Choose?
• Best for the largest headcount on a tight budget → Oidroy Bulk. Ten pairs versus five, and a bulk-packaged earbud is the cheapest way to cover a room.
• Best for shared-classroom identification → YFSFQS USB Type C. Five distinct colours and an on-ear body that is easy to spot and label.
• Best for repeated handing out and collecting back → Oidroy Bulk. The 4 ft tensile cord and solid 3.5 mm plug are specified for exactly this kind of wear.
• Best for blocking out a noisy room → Oidroy Bulk. Passive noise cancellation from the in-ear seal, versus no noise control on the YFSFQS set.
• Best for all-day comfort on bigger heads → YFSFQS USB Type C. Soft ear pads and an adjustable headband, with an age range that runs kid to adult.
• Best for mixed ages including very young children → Oidroy Bulk. Listed for children aged three and up, and light enough (3 g) for small ears.
• Best for travel and storage → Oidroy Bulk. The single-cord design on the YFSFQS set helps, but a 3 g in-ear pair with a small carry case packs down smaller.
In my opinion, the deciding factor is your device port, not the headphone. If your classroom, lab or teenager's school hardware runs on USB-C, I would buy YFSFQS USB Type C — the no-adapter connection is worth more than any other spec on this page, and the five-colour set handles shared use properly. If your devices still have 3.5 mm jacks and you need to cover more students per purchase, I would buy Oidroy Bulk: ten pairs, a cable specified for repeated shared use, and in-ear sealing that helps in a loud room. Check the current price on Amazon before you decide, since the pack sizes — five versus ten — change the real cost per student.
If the testing devices are USB-C, yes — it plugs in directly with no adapter, which is one less thing to troubleshoot under time pressure. If the devices use 3.5 mm jacks, Oidroy Bulk is the compatible choice.
YFSFQS USB Type C works with USB-C ports only. Oidroy Bulk uses a 3.5 mm jack, so it fits older phones, tablets, laptops and desktop headphone sockets, but not USB-C-only devices without an adapter.
Oidroy Bulk. It lists passive noise cancellation, and the in-ear seal cuts some background noise. The YFSFQS set lists no noise control, so it blocks essentially nothing around you.
Value depends on how many students you are covering and which ports you have. Oidroy Bulk gives you ten pairs in one bulk package; YFSFQS gives you five colour-coded USB-C pairs. For a USB-C room, the YFSFQS set avoids buying adapters on top, which is where the real savings sit. Check the current price on Amazon for both before you commit.
