How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a sealed, wired studio monitor for loud tracking rooms and broadcast work, choose Superlux HD661; if you need a wireless in-ear monitoring system that lets a whole band roam the stage cable-free, choose M-VAVE WP-10. Neither of these is a commuting product, and I want to be straight about that up front — if you're shopping open ear earbuds for commuting or the best bluetooth headphones for commuting, this pair won't get you there. But the search intent behind "open back monitor headphones" usually splits into two very different buyers, and this comparison sorts them out.
• Superlux HD661 — biggest strength: a proper over-ear monitoring headphone with a 40mm neodymium dynamic driver, 68Ω impedance and a wide 10Hz–20kHz range, plus two cable lengths and a pouch in the box.
• Superlux HD661 — biggest trade-off: it's a closed-back, wired design, so you're tethered to your interface or mixer and there's no wireless freedom at all.
• M-VAVE WP-10 — biggest strength: a complete 2.4GHz wireless in-ear monitor system — transmitter plus two receivers (expandable to six), auto pairing, mono/stereo switching, 30m open-air range and 5–6 hours of battery per charge.
• M-VAVE WP-10 — biggest trade-off: it's an in-ear monitoring chain, not a standalone headphone. You need something to plug the transmitter into, and the receivers are tiny clip-on units rather than full-size cups.
• Who each is for: Superlux HD661 suits engineers, drummers and broadcast users who want isolation and a cable; M-VAVE WP-10 suits performers and bands who want to move.
The HD661 is a sealed, over-ear monitor built around a 40mm dynamic driver with a neodymium magnet, rated at 102dB SPL (1mW) at 1kHz and covering 10Hz to 20,000Hz. Impedance sits at 68Ω, which is a useful middle ground — sensitive enough to run from a lot of studio gear, but not so low that it misbehaves on stronger headphone outputs. The closed-back, airtight enclosure is the whole point here: it keeps your mix in and the room out, which is exactly what you want when you're tracking drums next to a loud amp or reading copy in a noisy broadcast booth.
Who should buy it: studio engineers, live sound techs, drummers tracking with a click, podcasters and broadcast users who want isolation and a hard-wired connection they never have to charge. Who should skip it: anyone who wants to walk around while they listen, and anyone who wants in-ear monitors for stage use. There's no battery, no wireless link and no receiver here — it's a cable-first tool. If you're weighing this against earphones for commuting, the airtight design will block outside noise, but the wire and the over-ear fit make it a poor match for a train platform.
M-VAVE WP-10: Who It's For
The WP-10 is a different animal entirely. It's a 2.4GHz wireless in-ear monitor system — a transmitter and two receivers in the box, with the option to feed up to six receivers from one transmitter. Audio runs at 24bit/48kHz with a 20Hz–20kHz range and 105dB of dynamic range, which is the spec sheet talking about detail and headroom rather than a marketing flourish. Auto pairing means you power both ends on and they connect; there's no frequency hunting, which matters when you're setting up between songs.
The design decisions tell you who it's aimed at. Each receiver is compact with a sturdy back clip so it goes on a belt, pocket or collar, and the system claims up to 30 metres of open-air range. A one-tap mono/stereo toggle lets you run a simple mono mix or a proper stereo image depending on what your desk is sending. Battery life is 5–6 hours per charge over USB, and charge time is listed at 6 hours — so it's a rehearsal-and-gig device, not a leave-it-on-all-day device. You'll want a charging routine.
Who should buy it: gigging musicians, worship bands, small theatre casts, fitness instructors and anyone who needs several people hearing the same mix while moving freely. The one-to-many design is the standout feature — six receivers off one transmitter is genuinely useful for a band that wants a shared monitor mix. Who should skip it: solo listeners who just want headphones for a desk, and anyone who needs isolation from a loud room rather than a monitor feed. There are no ear tips, no cables and no wired fallback listed, so if the battery is flat, you're silent.
• Best for loud tracking rooms → Superlux HD661. The sealed, airtight over-ear design is built to work in high external noise.
• Best for band monitoring on the move → M-VAVE WP-10. One transmitter, up to six receivers, 30m range, clip-on packs.
• Best for wired reliability → Superlux HD661. Two cables and a gold-plated adapter; nothing to charge.
• Best for setup speed → M-VAVE WP-10. Auto pairing removes manual frequency matching.
• Best for stereo control → M-VAVE WP-10. The one-tap mono/stereo toggle is a real convenience on stage.
• Best for long sessions → Superlux HD661. No battery ceiling — plug in and keep working.
• Best for a single user at a desk → Superlux HD661. It's a headphone; the WP-10 is a monitoring system.
• Best for a group → M-VAVE WP-10. The expandable one-to-many link is the reason to buy it.
In my opinion, most people searching "open back monitor headphones" and landing between these two are actually solving a monitoring problem, not a listening problem — and that pushes me toward the M-VAVE WP-10 for performers, because a wireless IEM system with six-receiver expandability and auto pairing solves a problem no wired headphone can. That said, I'd buy the Superlux HD661 if my work happens in a loud room at a desk: the sealed over-ear fit, 68Ω impedance and dual cables make it the more dependable everyday tool. For commuting, honestly, buy neither — grab proper earphones for commuting instead. Whichever way you go, check the current price on Amazon before deciding, since value is the one thing these specs can't tell you.
how to open back headphones work
Open back headphones leave the outer cup open so air can move freely behind the driver, which typically widens the soundstage but lets sound in and out. Neither product here is open back — the Superlux HD661 is a closed-back sealed design, and the M-VAVE WP-10 is an in-ear wireless system.
what is open back studio headphones
It's a monitoring headphone whose cups are vented to the outside, trading isolation for a more spacious, speaker-like presentation. If you need isolation for tracking, the HD661's airtight closed-back design is the opposite approach and the more suitable one.
what are the best open back headphones
That depends entirely on your job — there's no single answer, and I won't pretend otherwise. For stage monitoring without cables, the M-VAVE WP-10 is the more capable pick; for sealed, wired studio and broadcast work, the Superlux HD661 is the one I'd reach for.
are open back headphones better
Not universally. Open back designs tend to sound more open but leak sound badly, which rules them out for loud rooms and live use. The HD661's closed-back isolation and the WP-10's wireless in-ear format each solve problems that open back headphones can't.
