If you want a colorful, ready-to-hand-out set of wired on ear headphones for a classroom or a big family, choose Flutesan 30; if you need rugged, adjustable on ear headphones built to survive daily student handling with a warranty behind them, choose Hengliyuan 50.
• Flutesan 30 — biggest strength: a 30-pack of wired on ear headphones in six bright colors, each individually packaged and sealed, with a dynamic driver rated 20 Hz–20,000 Hz and passive noise cancellation.
• Flutesan 30 — biggest trade-off: it is a straight bulk handout, not a durability story — ABS plastic and rubber construction, push-button control, and no swivel or retractable headband called out in the specs.
• Hengliyuan 50 — biggest strength: a 50-pack built for classrooms, with a reinforced 3.5 mm plug, a 1.2 m PVC cable, a retractable headband, swivel earcups and a 1-year warranty.
• Hengliyuan 50 — biggest trade-off: it comes in black only, so you lose the color-coding that makes handing out and collecting sets easier.
• Who each pick is for: Flutesan 30 for anyone who needs a large, cheerful, individually sealed batch of on ear headphones; Hengliyuan 50 for schools and programs that need a bigger count and expect hard daily wear.
The Flutesan 30 is a wired on ear headphone sold as a 30-pack, and the whole design reads like it was planned around distribution rather than around a single listener. Each pair is individually packaged and sealed, which matters if you are storing a class set, running a giveaway, or stocking a lending shelf where you want the next person to get something untouched. The colors are the other half of that idea: the listing describes six shades, including black, olive green, orange, rose red, light blue and dark blue, so you can color-code groups, tables or grade levels at a glance.
On the audio side, the specs are modest but coherent. A dynamic driver covers 20 Hz to 20,000 Hz, which is the full range you would expect from a general-purpose wired headphone, and the listing frames the tuning as stereo sound with rich bass and clear mids. Noise control is passive, meaning the earcup itself blocks some outside sound — there is no battery, no circuitry and no charging to think about. The 3.5 mm jack plugs into laptops, tablets, Chromebooks, plane seatback screens and anything else with a standard headphone port. The build is ABS plastic, rubber and nylon, with push-button controls on the cable.
In my opinion, this is the pick for the buyer who cares about quantity, variety and hygiene more than about surviving years of abuse. It suits teachers who want a bright, mixed-color set, parents buying for several kids at once, event organizers, and anyone who wants sealed spares on hand. I would skip it if your main worry is the cable or plug failing after months of tugging, or if you want every headphone in the set to look identical — the multi-color approach is the opposite of uniform.
The Hengliyuan 50 is a bulk classroom headphone sold as a 50-pack under the model HLY002, and every line of its spec sheet points at one job: staying alive in a room full of students. The cable is PVC, 1.2 m or about 47.25 inches long, which the listing describes as enough slack for children to move without yanking the plug. The 3.5 mm plug gets a reinforced treatment that the brand says extends usable life by at least 6 to 12 months — a claim about the connector design rather than a promise about any individual pair, so treat it as a durability intent, not a guarantee.
The comfort and fit story is the strongest part of the design. The headband is retractable, so it adjusts between adult and child head shapes, and the earcups swivel, which makes the set easier to stack, carry and store between lessons. The ear cushions are soft sponge for longer wear, and the housing is described as lightweight and adjustable with rugged construction in mind. Impedance is 32 ohm with 92 dB sensitivity, which is an easy load for a laptop, Chromebook or tablet headphone jack to drive. Noise control is sound isolation, so it is the cushion and the seal doing the work, not electronics. The brand also backs it with a 1-year warranty and after-sales support, and it is aimed at kids, teens and adults.
I recommend the Hengliyuan 50 for schools, libraries, testing rooms and any program that checks out headsets to students and needs them to come back working. It is also the more sensible choice when you want one consistent, plain black set rather than a rainbow. Skip it if color variety is the point of your purchase, or if you only need a small number of headphones — a 50-pack is a lot of inventory.
• Best for a bigger set count → Hengliyuan 50. It ships as 50 units versus 30, so it covers a larger roster in one go.
• Best for color variety → Flutesan 30. Six shades let you sort by table, group or grade without labeling anything.
• Best for durability features → Hengliyuan 50. Reinforced 3.5 mm plug, PVC cable, retractable headband and swivel earcups all point at hard daily use.
• Best for individually sealed handouts → Flutesan 30. Every pair is packaged and sealed on its own, which is ideal for giveaways and lending.
• Best for fit across ages → Hengliyuan 50. The retractable headband is explicitly designed to span adult and child head shapes.
• Best for simple audio on a standard jack → Flutesan 30. A 20 Hz–20,000 Hz dynamic driver and a 3.5 mm jack are all you need for laptops, tablets and seatback screens.
• Best for storage and transport → Hengliyuan 50. Swivel earcups make a full class set easier to stack and pack away.
• Best for warranty peace of mind → Hengliyuan 50. It carries a 1-year warranty and dedicated after-sales support; Flutesan 30 does not list one.
If I were outfitting a classroom, library or any shared-use program, I would buy the Hengliyuan 50. The reinforced plug, PVC cable, retractable headband, swivel earcups and 1-year warranty are all design decisions aimed at the exact thing that kills bulk headphones — rough handling by students. The Flutesan 30 is genuinely the better fit for a different job: colorful, individually sealed, and easy to hand out in mixed sets, and I would choose it without hesitation for giveaways, family use or color-coded groups. But for durability and support, my money goes to the Hengliyuan 50. Either way, check the current price on Amazon before you commit, since bulk sets swing a lot.
how to clean on ear headphones
Wipe the earcups and headband with a soft, slightly damp cloth, then dry them fully before use. For sponge cushions like the ones on the Hengliyuan 50, keep water out of the foam and never soak the drivers or the cable. On the Flutesan 30, the ABS plastic and rubber surfaces wipe down easily, but avoid solvents that could dull the finish.
how to fit on ear headphones
On ear headphones rest against the outside of your ear rather than around it, so the headband length is what sets the fit. The Hengliyuan 50 uses a retractable headband that adjusts for both adult and child head shapes, while the Flutesan 30 has an adjustable headband as well. Aim for a snug but not pinching fit, with the cushions sitting flat against your ears.
how to ear headphones
If you mean how to wear them, slide the headband over your head with the earcups resting on your ears — "on ear" means the cushion presses against the ear rather than sealing around it. Check that the left and right markers line up correctly, since reversing them flips the stereo image. Both headsets here are wired, so run the 3.5 mm plug to your laptop, tablet or Chromebook and adjust volume from the source.
how to open ear headphones
There is no user-serviceable opening on either model — the housings are sealed units, and prying them apart will damage the drivers. If a cable or plug fails, that is a warranty matter on the Hengliyuan 50, which includes a 1-year warranty, rather than a repair job. For the Flutesan 30, treat each pair as a sealed unit and replace it if it stops working.
