If you want a single pair of stereo on-ear headphones with a wide 20 Hz–20,000 Hz frequency range and a remote media control on the cable, choose Flutesan 30; if you need a ten-pack of on-ear headphones with a built-in microphone for calls and online classes, choose Bulktech 10.
• Flutesan 30 — biggest strength: A full-range 20 Hz–20,000 Hz dynamic driver and a wired 3.5 mm connection with an inline remote media control, in a single on-ear unit.
• Flutesan 30 — biggest trade-off: No microphone and no noise control, and it ships as one headphone rather than a set — fine for one listener, awkward if you need to equip a group.
• Bulktech 10 — biggest strength: Ten on-ear headphones in one set, each with a microphone and a 3.5 mm jack, built with adjustable headbands, soft ear cushions and swivel cups for storage.
• Bulktech 10 — biggest trade-off: The stated frequency range is far narrower, and there is no noise control — these are built for voice and everyday listening, not critical music listening.
• Pick Flutesan 30 if you are one person who wants clean stereo sound with a cable remote and no mic to worry about.
• Pick Bulktech 10 if you are buying for a classroom, a family, a call center or a group where every listener needs a mic and a spare.
The Flutesan 30 is a single wired on-ear headphone. On-ear means the earpads sit against the ear rather than around it, and the enclosure here is built from ABS, nylon, plastic and rubber — a mix that reads as practical rather than precious. The earpiece shape is listed as rounded, the style is simply "on ear," and the whole thing is wired through a 3.5 mm jack. That is the connector that still shows up on laptops, tablets, school Chromebooks, in-flight entertainment jacks and plenty of budget phones.
The part that matters most in the data is the audio spec. Flutesan lists a dynamic driver with a frequency range of 20 Hz to 20,000 Hz. That is the full span of human hearing, and it is the range you want when the goal is music, movies and general listening — deep bass at the low end, crisp mids and treble up top. The product copy describes it as high-fidelity stereo with rich bass and clear mids, which lines up with a driver that is specced across the whole audible band.
There is also a media control on the cable. Control type is "Media Control," control method is "Remote," which means play, pause and track handling without reaching for your device. There is no microphone and no noise control, so this is not a headset for calls — it is a listening headphone.
Bulktech 10: Who It's For
The Bulktech 10 is a set of ten wired on-ear headphones, each with a microphone and a 3.5 mm connector. The color description is "leather headphones with mic mixed" — so the earcups use a leather-style covering and the set arrives in mixed colors rather than one uniform shade. The enclosure material is listed as plastic, and the age range covers both kids and adults, which tells you the target is shared, multi-user environments rather than one careful adult owner.
The build details are where this set earns its place. Bulktech describes a lightweight, adjustable headband that fits adults and children, soft ear cushions for long sessions, swivel cups that let the headphones stack flat for storage, and a thick, durable cable. The cable length is listed as 5 feet, which is generous enough to reach a laptop or a desktop tower without a fight. Swivel cups plus a ten-pack is a genuinely useful combination — it means a class set can be handed out, collected and stacked in a drawer without a tangled pile.
The microphone is the headline feature. Bulktech describes it as a rotating, noise-reducing mic aimed at online meetings, virtual classes, seminars and recordings. Frequency range is listed as 20–100, which is a voice-band spec rather than a full music range — the numbers point at speech intelligibility, not audiophile listening. Impedance is 32 ohm, a common, easy-to-drive figure for phones, tablets and computers.
Buy the Bulktech 10 if you are equipping a classroom, a kindergarten, a library, a computer lab, a health center or a family with several kids, and every user needs a mic and a pair to call their own. Skip it if you want one pair for yourself and you care about full-range music reproduction — the spec sheet points elsewhere.
• Best for music and movie sound range → Flutesan 30. The 20 Hz–20,000 Hz range covers the full audible band; the Bulktech 10 is listed at 20–100.
• Best for microphone use → Bulktech 10. Every unit includes a mic; the Flutesan 30 has none.
• Best for a group, class or family → Bulktech 10. Ten headphones per set versus one.
• Best for cable controls → Flutesan 30. It has an inline remote media control; the Bulktech 10 lists remote control method but no media control type.
• Best for storage and stacking → Bulktech 10. Swivel cups are designed to fold flat and stack.
• Best for a single traveler → Flutesan 30. One pair, one cable, one 3.5 mm jack for plane and laptop use.
• Best for young kids sharing equipment → Bulktech 10. The adjustable headband is explicitly sized for kids and adults, and the thick cable is built for daily handling.
• Best for laptop and tablet listening without calls → Flutesan 30. Nothing to configure, no mic to manage.
In my opinion, the right pick comes down to one question: is this for one listener or many? If it is you, alone, listening to music or a movie through a laptop or a plane seat, I would buy the Flutesan 30. The 20 Hz–20,000 Hz driver range and the inline media control are exactly what a single-listener headphone needs, and nothing on the spec sheet is wasted on features you will not use.
If it is a group — a classroom, a lab, a family with several kids, a small team taking calls — I would buy the Bulktech 10. Ten units, a mic on each, swivel cups for stacking and a 5-foot cable are the specs that matter when hardware gets shared, handed out and put away every day.
FAQ
how to wear over the ear headphones
how to clean on ear headphones
Wipe the earcups and headband with a soft, slightly damp cloth, and avoid soaking the pads or letting liquid near the driver or the cable joint. The Flutesan 30's ABS, nylon, plastic and rubber surfaces wipe down easily; the Bulktech 10's leather-style cushions should be wiped gently rather than scrubbed. Unplug both before cleaning, and never submerge them.
how to ear headphones
If you mean how to get the best sound from on-ear headphones, start with fit: a light, even seal on both ears gives you the most bass and clarity the driver can produce. On the Flutesan 30, the 20 Hz–20,000 Hz dynamic driver rewards a good seal with fuller low end. On the Bulktech 10, remember the listed range is tuned for voice, so music will sound thinner than a full-range pair.
The Bulktech 10 does — every one of the ten units includes a microphone with a 3.5 mm connector, which is why it suits calls, virtual classes and recordings. The Flutesan 30 does not list a microphone, so it is a listening-only headphone. If you need to talk, the Bulktech 10 is the one to pick.
