If you want a lightweight, foldable studio headphone with a detachable-ready swivel design, low clamping fatigue and a 6.35 mm plug straight out of the box, choose Yamaha HPHMT5W; if you need maximum isolation, higher sensitivity for loud, clean playback and field-replaceable parts, choose KRK KNS 8402.
• Yamaha HPHMT5W — biggest strength: a 40 mm dynamic driver with CCAW voice coils covering 20 Hz–20 kHz, wrapped in a three-dimensional swivel and folding-arm design that makes long sessions and travel easier.
• Yamaha HPHMT5W — biggest trade-off: 51 ohm impedance means it wants a bit more juice from weak phone outputs, and the cable is a fixed straight 3 m run rather than a swappable one.
• KRK KNS 8402 — biggest strength: up to 30 dBA of isolation from a closed-back circumaural design, 124 dB max peak SPL and field-replaceable pads and cable.
• KRK KNS 8402 — biggest trade-off: a 3.5 mm jack means you'll need your own adapter for gear with a quarter-inch output, and it's a fixed-cable design apart from the replaceable parts.
• Who each is for: Yamaha HPHMT5W suits home producers and casual listeners who move around and want a light, folding, all-day pair; KRK KNS 8402 suits tracking, mixing and critical listening where isolation and durability matter most.
The HPH-MT5W is built around a simple idea: comfortable, well-balanced monitoring you can wear for hours without thinking about your ears. Yamaha pairs 40 mm dynamic drivers with CCAW voice coils and a 20 Hz–20 kHz frequency range, so the tuning is aimed at even-handed reproduction rather than a boosted low end. The 51 ohm impedance is a middle-of-the-road figure — it plays fine from a laptop or interface, but it rewards a headphone amp more than a low-impedance consumer pair would.
The physical design is where this one earns its place. The three-dimensional swivel lets the cups fold flat against your chest or into the included bag, and the adjustable slider length plus low-resistance synthetic leather cushions are there specifically to cut fatigue over long sessions. The ABS housing and folding arm are meant to survive a bag, a desk drawer and the occasional knock. You get a straight 3 m cable, a 6.35 mm stereo adapter plug and a carrying bag in the box.
Buy it if you're a home producer, podcaster or everyday listener who wants one pair that folds up, feels light on the head and plugs straight into an interface or mixer without hunting for an adapter. Skip it if you record in a live room next to open mics and need maximum isolation, or if you want to replace the cable yourself down the road — the straight cable is fixed, and at 51 ohms it won't reach its best from a weak phone jack.
The KNS 8402 is the more purpose-built studio tool of the two. KRK's closed-back circumaural cup design provides up to 30 dBA of isolation, which is the headline number here: it cuts bleed into microphones during tracking and shuts out room noise when you're trying to focus. With a 124 dB max peak SPL and very low distortion at high levels, it stays composed when you push volume, and the 36 ohm impedance makes it easier to drive from modest sources than the Yamaha.
The frequency range also runs 20 Hz–20 kHz, but the intent is different. KRK describes a natural, consistent voicing intended as a reference standard wherever you work — studio, home or on the road for track checks. The acoustic cellular foam pads with leatherette covers are a memory-foam, form-fitting design, and the impact-resistant plastic shell keeps the weight down at 210 g. Field-replaceable pads and cable are the durability story: you service the parts that wear out instead of replacing the whole headphone.
Buy it if you track vocals or instruments and can't have headphone bleed on the take, you mix in a noisy space, or you want a headphone you can keep running for years by swapping pads and cable. Skip it if you want a quarter-inch plug without an adapter, or if a folding, ultra-packable frame matters more to you than isolation and serviceability.
• Best isolation → KRK KNS 8402. Up to 30 dBA of isolation from the closed-back circumaural design versus Yamaha's sound-isolation approach on a lighter, more open-feeling frame.
• Best for loud, clean playback → KRK KNS 8402. 124 dB max peak SPL with low distortion, and 36 ohms makes it easier to drive.
• Best for long, fatigue-free wear → Yamaha HPHMT5W. Low-resistance synthetic leather cushions and a swivel design built around extended sessions.
• Best for travel and small desks → Yamaha HPHMT5W. The folding arm and three-dimensional swivel let it collapse into the included bag.
• Best for plug-and-play into a mixer or interface → Yamaha HPHMT5W. The 6.35 mm jack and included 6.3 mm adapter mean no extra purchase to get started.
• Best for repairability → KRK KNS 8402. Field-replaceable pads and cable, backed by a 1-year warranty description, versus a fixed cable on the Yamaha.
• Best for tracking near microphones → KRK KNS 8402. The isolation is the deciding factor when bleed ruins a take.
• Best for casual listening and light gear → Yamaha HPHMT5W. At 51 ohms it still works from a laptop, and the tuning is aimed at balanced everyday listening.
My Verdict
I'd only choose the Yamaha HPHMT5W instead if comfort, folding portability and a quarter-inch plug out of the box matter more to you than isolation and repairability — for a home desk or a commute, that's a genuinely reasonable trade. Either way, check the current price on Amazon before you commit, since the value math changes with whatever each pair is going for.
The KRK KNS 8402. Its closed-back circumaural design provides up to 30 dBA of isolation, which reduces headphone bleed into the microphone. The Yamaha relies on sound isolation too, but it isn't rated for bleed reduction the way the KRK is.
The KRK KNS 8402, at 36 ohms versus the Yamaha's 51 ohms. Lower impedance generally means less power is needed for the same volume level, and the KRK also reaches 124 dB max peak SPL. The Yamaha will still work from most laptops, but it benefits more from a dedicated amp.
Yes for the KRK, no for the Yamaha. The Yamaha HPHMT5W ships with a 6.35 mm connection plus a 6.3 mm stereo adapter plug, so it fits mixers and interfaces directly. The KRK KNS 8402 has a 3.5 mm jack, so you'll need your own adapter for quarter-inch outputs.
Both are designed for it, but differently. The Yamaha uses low-resistance synthetic leather cushions and a swivel design explicitly aimed at reducing fatigue, while the KRK uses form-fitting memory foam pads. The KRK is lighter at 210 g versus the Yamaha's 0.25 kg, which some people prefer over a long day.
The KRK KNS 8402, in my opinion. Its pads and cable are field-replaceable, so you can service the parts that wear first. The Yamaha's design is durable in its own right — ABS housing and a folding arm — but its cable isn't user-replaceable in the same way.
