• SAMSON SR450 — biggest strength: Purpose-built listening gear. On-ear, closed-back, 40 mm dynamic drivers with rare earth magnets, a 20 Hz–20,000 Hz range and a stainless-steel headband. Built to be worn for long sessions.
• SAMSON SR450 — biggest trade-off: It's one pair, wired only, with no wireless option and no inline anything beyond a media control. If you need to equip a room, one unit doesn't get you there.
• Hengliyuan 50 — biggest strength: Volume and logistics. 50 units in one box, 3.5 mm plugs with reinforced strain relief, a retractable headband that fits kids and adults, and swivel earcups for easy storage.
• Hengliyuan 50 — biggest trade-off: It's a fleet product. Plastic housing, sponge cushions and a spec sheet written for durability and replaceability rather than for critical listening.
• Who each is for: SAMSON SR450 for the individual listener, musician or editor who wants one dependable pair. Hengliyuan 50 for the teacher, IT coordinator or program manager who has to hand out headphones to a whole group.
The SR450 reads like a headphone designed by people who care about what comes out of the driver. On-ear, closed-back, 40 mm dynamic drivers with rare earth magnets, and a stated frequency range of 20 Hz to 20,000 Hz at 32 ohms. That combination — closed back plus a wide stated range — is the classic recipe for keeping outside noise out and detail in, whether you're tracking in a noisy room or just trying to hear a bass line on a bus.
The build story matters too. Stainless steel in the enclosure, an ultra durable headband, and a headband that's fully adjustable and contoured to the head for a low-profile fit. Wide cushions on both the earpads and the headband are there specifically to reduce fatigue over long sessions, and the design is explicitly voiced for reference-quality sound with a frequency response tuned to limit ear fatigue. That's a headphone that wants to stay on your head for hours, not twenty minutes.
Who should buy it: the individual. A musician tracking at home, a student editing audio, someone who wants one pair that does running, recording and everything between. A 1/8" to 1/4" adapter is included, so it moves between a laptop and a proper audio interface without a trip to the store. It's also a 32 ohm load, which is friendly to phones and laptops without a dedicated amp.
Hengliyuan 50: Who It's For
This is not really a headphone in the same category as the SR450. It's a logistics solution that happens to be shaped like a headphone. The model is HLY002, sold as a 50 pack, and the entire feature list is written from the perspective of the person who has to keep 50 of them working.
Start with the cable. It's sturdy PVC, 1.2 m or about 47.25 inches long, which gives kids real slack at a desk or a Chromebook cart without dragging on the floor. The 3.5 mm plug gets a special reinforcement process at the joint — the spot where cheap headphones always die — and the spec sheet claims that extends usable life by at least 6 to 12 months. That's a design decision aimed squarely at the failure point, and it tells you what the manufacturer thinks the main risk is.
Fit is handled with a retractable headband that adjusts across adult and child head shapes, plus swivel earcups so they collapse for storage in a bin or a drawer. Cushions are soft sponge, the housing is lightweight and adjustable, and the whole thing is described as rugged for its class. Ear placement is on-ear with a circular earcup, impedance is 32 ohms, sensitivity is 92 dB, and there's a 1 year warranty with a stated quick-response service promise.
Who should buy it: schools, libraries, testing labs, computer carts, after-school programs, and anyone who needs a class set that plugs into 3.5 mm jacks on Chromebooks, laptops and desktop PCs. The kid-teen-adult age range means one SKU covers a whole building.
Who should skip it: the individual listener. If you want one pair for music, mixing or commuting, buying 50 is absurd, and the sponge cushions and plastic housing aren't aimed at the kind of detail the SR450 is chasing. This is a fleet purchase, not a listening purchase. Also worth flagging: the audio fields on this sheet are unusual — a frequency response listed as 20.4 MHz is not a meaningful audio figure, so treat the SR450's 20 Hz–20,000 Hz spec as the one you can actually compare against.
• Best for critical listening → SAMSON SR450. 40 mm dynamic drivers, rare earth magnets, and a stated 20 Hz–20,000 Hz range with a closed-back enclosure.
• Best for equipping a whole room → Hengliyuan 50. 50 units, one box, one 3.5 mm standard across every device in the room.
• Best for long listening sessions → SAMSON SR450. Wide cushions on the earpads and headband, plus a response voiced to limit ear fatigue.
• Best for kids and mixed-age groups → Hengliyuan 50. The retractable headband is designed to fit both adult and child head shapes.
• Best for surviving daily handling → Hengliyuan 50. Sturdy PVC cable, reinforced 3.5 mm plug, swivel earcups for storage, and a stated service life extension of at least 6–12 months.
• Best for a single durable build → SAMSON SR450. Stainless steel enclosure and an ultra durable headband in an 8.64 ounce package.
• Best for plugging into pro audio gear → SAMSON SR450. A 1/8" to 1/4" adapter is included, and 32 ohms is easy to drive.
• Best for storage and transport in bulk → Hengliyuan 50. Swivel earcups collapse flat, which is exactly what you want in a classroom bin.
If I were buying for myself, I'd take the SAMSON SR450. The reason is simple: it's the only one of these two designed around sound quality rather than around surviving a classroom. Closed-back on-ear with 40 mm drivers, a stainless-steel frame and cushions built for long wear is a combination that serves a musician, an editor or a focused listener. I'd pick the Hengliyuan 50 only if my job were to hand out headphones to 50 people at once — in which case the reinforced plugs, the 1.2 m cables and the retractable fit are exactly the right priorities. Two different problems, two different answers.
how to fit on ear headphones
On-ear headphones rest against the outer ear rather than around it, so the fit is about the headband, not the cup. On the SAMSON SR450, the fully adjustable, contoured headband sets the clamping force and the on-ear cushions sit flat against your ears. On the Hengliyuan 50, the retractable headband is designed to span both adult and child head shapes. Adjust until the cups sit centered and even, then stop — extra pressure doesn't improve isolation.
how to clean on ear headphones
The contact points are the cushions and the headband padding, not the drivers. Wipe the earpads and headband with a lightly damp cloth and let them air dry completely before use, and keep liquid away from the driver openings. The Hengliyuan 50 uses soft sponge cushions and the SAMSON SR450 uses wide cushions on both the earpads and the headband, so those are the surfaces to focus on. For a 50-unit classroom set, a quick wipe-down between handouts is the practical routine.
how to open ear headphones
If you mean opening the earcup to reach the driver or wiring, don't — neither of these is sold as a user-serviceable design, and prying a closed housing apart can damage the driver or the cable joint. If you mean opening up the sound, that's about the seal: on-ear models like both of these rely on the cups sitting flat against your ears. The SAMSON SR450's closed-back design reduces ambient noise; the Hengliyuan 50 also uses sound isolation rather than active noise control. A clean, even fit gets you the most from either.
how to ear headphones
If what you actually want to know is how they sit on your ears: both of these are on-ear models, meaning the cushion presses against the ear rather than surrounding it. The SAMSON SR450 is contoured to the shape of the head for a low-profile fit, and the Hengliyuan 50 has circular earcups on a retractable band. Neither is a wireless design — both are wired 3.5 mm — so there's no pairing step, just plug in and adjust. If you prefer the feel of a cup that surrounds the ear entirely, neither of these is that style.
