If you want serious, long-session monitoring sound with a rugged aluminium build and a detachable cable, choose Rode RØDE NTH-50; if you need a bulk class set of fifty lightweight on-ear headphones for students and shared devices, choose Hengliyuan 50.
• Rode RØDE NTH-50 — biggest strength: a custom-matched 40mm driver with a resonant chamber, tuned for deep-but-balanced bass and clear mids and treble, plus strong passive isolation for critical listening.
• Rode RØDE NTH-50 — biggest trade-off: it is a single premium pair for one listener, it is wired only, and it needs more careful handling than a throw-in-a-bin classroom headset.
• Hengliyuan 50 — biggest strength: you get 50 wired on-ear headphones in one box with reinforced 3.5mm plugs, which is exactly what a classroom, library or computer lab needs.
• Hengliyuan 50 — biggest trade-off: the sound is basic and the plastic build is built for durability in kids' hands, not for studio accuracy.
• Who each pick is for: Rode RØDE NTH-50 for DJs, engineers, filmmakers and creators; Hengliyuan 50 for schools, teachers and anyone equipping a room full of students.
The NTH-50 is a professional on-ear headphone, and the spec sheet reads like one. The heart of it is a custom-matched 40mm dynamic driver sitting inside what Rode calls a resonant chamber — the design goal being rounded, deep bass that doesn't smear the midrange or soften the treble. Add an acoustic design aimed at accurate frequency response and ultra-low distortion, and you have a headphone meant for hearing what's actually in a mix rather than what flatters it.
The rest of the package backs that up. Frequency range runs 20 Hz to 35 kHz, impedance is 32 ohm, sensitivity is 102 dB, and the earcups are closed-back on-ear with aluminium and fabric/foam construction. Passive noise isolation is a headline feature here — it's there for critical monitoring, so you can track or edit in a noisy room without reaching for active cancellation. The contoured headband and 220 g weight are aimed squarely at wearing fatigue over long sessions.
Connectivity is a detachable cable with a locking connector and dual-sided attachment, so you can run the cable into either earcup — genuinely useful if you're working at a desk and want the wire out of the way. There's also a remote on the cable for control, a 3.5mm jack, and a lifetime warranty with the product designed and made in Rode's Sydney facilities.
Who should buy it: DJs, sound engineers, filmmakers and content creators who sit in headphones for hours and care about isolation and detail. Also anyone who wants one pair that will survive years of daily use.
Who should skip it: if you're buying for a class of thirty students, this is the wrong tool — one pair, one listener, and it deserves better treatment than a shared equipment cart. And if you want wireless, this is a wired headphone.
The Hengliyuan 50 is a different product solving a different problem entirely. The name says it: 50 pack, bulk headphones for classrooms, students and kids, wired, 3.5mm, for libraries, Chromebooks, laptops and desktop computers. You are not buying a headphone here, you are buying a class set — and the design decisions follow from that.
Start with the cable. It's 1.2 m (about 47.25 inches) of sturdy PVC, which is a deliberate choice: long enough that a child isn't yanking the plug out of a Chromebook every time they turn their head, and tough enough to survive being coiled, folded and stuffed into a drawer. The 3.5mm plug gets a special reinforcement process, and Hengliyuan states that this extends usable life by at least 6 to 12 months — a very classroom-shaped claim, and a reasonable one for a shared-device environment.
The physical design is all about flexibility. The headband is retractable so it fits both adult and child head shapes, the earcups swivel so the whole thing folds down for storage, and the soft sponge cushions are there for comfort over a lesson rather than for isolation or accuracy. The housing is lightweight and adjustable, built for rugged durability in the sense that matters here: getting knocked around by kids and still working tomorrow. Enclosure is plastic with a circular on-ear earpiece shape, sensitivity is 92 dB, impedance is 32 ohm, and there's a touch controller with media control and sound isolation. It's wired, with no wireless option. Warranty is 1 year, and the listing includes cable, ear cushions and headband as the built-in media.
Who should buy it: schools, teachers, librarians, IT staff and anyone who needs fifty working headsets at once for students on shared computers. Also parents buying for a kid who is hard on their gear.
Who should skip it: anyone chasing audio quality for music production, mixing or critical listening. The 92 dB sensitivity and plastic build tell you this is a utility headphone, not a monitoring tool.
• Best for audio fidelity → Rode RØDE NTH-50. Custom 40mm driver, resonant chamber, 20 Hz–35 kHz, ultra-low distortion, 102 dB sensitivity. This is the one you buy to hear things.
• Best for passive noise isolation → Rode RØDE NTH-50. Isolation is designed in for critical monitoring, which matters in a loud room or a live DJ booth.
• Best for equipping a whole classroom → Hengliyuan 50. Fifty units in one box, 3.5mm, wired, ready for Chromebooks and lab PCs.
• Best for surviving kids → Hengliyuan 50. Reinforced plug, sturdy PVC cable, retractable headband, swivel cups, sponge cushions — all chosen for rough shared use.
• Best for long-session comfort at a desk → Rode RØDE NTH-50. Contoured headband, 220 g, aluminium-and-foam build aimed at reducing wearing fatigue.
• Best for storage and transport in bulk → Hengliyuan 50. Swivel earcups fold flat, which is how you store fifty of anything without a tangle.
• Best for cable flexibility → Rode RØDE NTH-50. Detachable cable with a locking connector and dual-sided attachment, so you can route it either way.
• Best for durability guarantee → Rode RØDE NTH-50. Lifetime warranty on the Rode versus 1 year on the Hengliyuan.
In my opinion, these two aren't really competitors — they're answers to two different questions, and the honest recommendation depends entirely on which question you're asking. If you're a DJ, engineer, filmmaker or creator and you want one pair of on-ear headphones for accurate, isolated, long-session listening, I'd buy the Rode RØDE NTH-50: the custom driver, resonant chamber, aluminium build, detachable locking cable and lifetime warranty are the things I'd want to rely on every day. If you're a teacher, school or IT buyer who needs fifty working headsets for students on shared computers, I'd buy the Hengliyuan 50 without hesitation — a single premium pair is useless for a room of thirty kids. Check the current price on Amazon for whichever one matches your situation, since these sit in very different budget brackets.
FAQ
how to clean on ear headphones
how to fit on ear headphones
On-ear cups sit against the outer ear rather than around it, so you adjust the headband until the pads rest flat and evenly on both ears without pressing hard. The RØDE NTH-50 uses a contoured headband for long-wear comfort, while the Hengliyuan 50 has a retractable headband that fits both adult and child head shapes, with swivel earcups that help you seat them properly.
how to ear headphones
If you mean which way the cups go: the cable side is the bottom, and the L/R markings tell you which cup goes on which ear — on-ear models like these two only sound right when worn the correct way round. The RØDE NTH-50 accepts its detachable cable into either earcup, so you can put the wire on the side that suits your setup.
how to open ear headphones
If you're asking how to open them up for storage or to swap parts, don't pry the cups apart. The Hengliyuan 50 folds and swivels its earcups for carrying and storage, and its cushions and headband are the intended user-serviceable parts. The RØDE NTH-50 is not a user-openable design — the serviceable item is the detachable cable, which unlatches from the locking connector rather than requiring you to open the housing.
