• Rockville PRO-M50 — biggest strength: a complete wired monitoring package: 40mm neodymium drivers, a flat-ish frequency curve (10Hz–25KHz), 32 ohm impedance, a detachable coiled OFC cable with a gold-plated 1/4" adapter, interchangeable leather and suede ear pads, and a hard leather travel case.
• Rockville PRO-M50 — biggest trade-off: it is wired only and it is a listening tool. It records nothing on its own, and the coiled cable plus over-ear clamp means it is not the most discreet thing to wear on a commute.
• MAONO PM320S — biggest strength: a genuine XLR condenser mic with a 16mm capsule, cardioid pattern, 20Hz–18KHz response and a full kit — boom arm, metal shock mount, pop filter, windscreen and XLR cable — so it is ready to mount and record.
• MAONO PM320S — biggest trade-off: it needs a stable 48V phantom power source (audio interface, mixer or preamp). Plug it into a plain laptop jack and it will not work.
• Pick Rockville PRO-M50 if you need to hear accurately — monitoring, mixing, editing, silent practice, or listening to your own recordings.
• Pick MAONO PM320S if you need to capture accurately — podcasting, streaming, vocals, voice-over and content creation.
The PRO-M50 is built around one idea: let you hear what is actually there. The 40mm neodymium drivers and the flat frequency curve exist so that bass, mids and highs arrive in proportion rather than flattered. Rockville describes it as a monitoring headphone, and the spec sheet backs that framing — a 10Hz to 25KHz range that reaches past what human ears can register, and 32 ohm impedance, which is low enough that most phones, laptops and small interfaces can drive it without a dedicated amp.
The second thing that defines it is isolation. It is a closed-back, over-ear design with ear cups that seal tight, which is why it makes sense for recording and podcasting. If you are tracking a vocal while a backing track plays, or editing at a desk with a fan and a fridge humming nearby, that sealed cup is doing real work. You hear your material, not your room.
Where it earns its keep day to day is comfort and logistics. You get two sets of cushions — leather and suede — and swapping them changes both the feel and the seal, which matters when a session runs long. The headband is leather over stainless steel arms, so the frame is meant to survive being tossed in a bag, and the hard leather case plus the detachable cable make that realistic. The coiled OFC cable runs 51 inches and stretches to 158 inches, which is the difference between sitting at a desk and pacing a room mid-take. The gold-plated 3.5mm plug and included 1/4" adapter cover both consumer gear and studio interfaces.
Who should skip it: anyone who wants wireless, anyone who needs a microphone rather than a monitor, and anyone who wants a tiny in-ear for the gym. It is a wired, full-size studio tool. If that is your job, it is the right shape of product. If it is not, it will sit in the case. And if budget is the deciding factor, check the current price on Amazon before you commit.
The PM320S is a different animal entirely: it is the front end of your signal chain, not the back. Inside is a large 16mm condenser capsule with a cardioid polar pattern, and that combination is why it is aimed at podcasting, streaming, vocals and home studio work. Cardioid means it favours what is in front of it and pushes down sound arriving from the sides and rear — a genuinely useful trait when your "studio" is a bedroom with a window and a noisy street outside.
The kit is the story as much as the capsule. In the box you get the microphone, a boom arm, a metal shock mount, a pop filter, a foam windscreen and an XLR-to-XLR cable. That is not a token accessory bundle; the shock mount and pop filter are the two things that most often ruin beginner recordings — desk thumps and harsh p/b plosives — and they are included rather than sold separately. The metal housing and folding boom arm bracket also mean it handles being set up and torn down repeatedly, which is normal life for a streamer or a travelling creator.
The trade-off is power and connectivity, and it is not a small one. This is an XLR condenser that requires a stable 48V phantom power supply. You need an audio interface, mixer or preamp in the chain. It will not plug straight into a laptop's headphone jack and work. The spec also lists a lithium-ion battery as required, so plan your setup accordingly rather than assuming it runs off USB.
Who should skip it: anyone who wants a one-cable USB mic, anyone without an interface or mixer, and anyone who only wants to listen. It is a capture device. If you already own an interface — or you are ready to buy one — it slots in cleanly and does the job it was designed for.
• Recording your voice → MAONO PM320S. It is a microphone; the Rockville is not. This one decides the category for you.
• Monitoring, mixing or editing → Rockville PRO-M50. The flat curve and sealed cups are built for judging audio, not making it.
• Working in a noisy room → Rockville PRO-M50 for listening, MAONO PM320S for recording. Closed cups block sound coming in; the cardioid pattern rejects sound arriving off-axis.
• No extra gear on your desk → Rockville PRO-M50. It runs from a 3.5mm jack with a 1/4" adapter in the box. The PM320S needs an interface or mixer with 48V.
• Everything in one purchase → MAONO PM320S. Boom arm, shock mount, pop filter, windscreen and XLR cable are all included. The Rockville's kit is case, spare pads and adapter.
• Travel and storage → Rockville PRO-M50. The hard leather case and detachable coiled cable are made for packing up. The PM320S folds down too, but it is a mounted desk tool.
• Long sessions → Rockville PRO-M50. Interchangeable leather and suede cushions let you change the feel when a session drags on.
• Studio-quality vocal tone on a small setup → MAONO PM320S. The 16mm condenser capsule and high SPL handling are the reason it sounds like broadcast gear rather than a headset mic.
In my opinion, the honest answer is that these two products do not compete — they complete each other, and most people building a home setup will eventually want both. If I had to pick one today, I would pick the MAONO PM320S, because a microphone is the piece you cannot substitute. The PM320S is a real XLR condenser with a 16mm capsule, a cardioid pattern and a kit that removes the two most common beginner problems, and it works with the interface most creators end up owning anyway. The Rockville PRO-M50 is the better product in isolation — the build, the case, the two pad sets and the flat monitoring curve are genuinely well thought out — but monitoring can be done with almost anything in a pinch. Capturing clean audio cannot. Buy the mic first, then add the PRO-M50 when you want to hear your recordings properly.
No. It is a wired, closed-back over-ear headphone for studio monitoring, recording and podcasting. It plays audio back; it does not capture it. The MAONO PM320S is the microphone in this comparison.
Yes, or a mixer or preamp. It is an XLR condenser that requires a stable 48V phantom power supply, so it will not work plugged directly into a standard laptop headphone jack. Plan for the interface as part of your setup.
For recording a podcast, the MAONO PM320S is the correct tool — it captures your voice and its cardioid pattern rejects room noise. For listening back to edits and judging levels, the Rockville PRO-M50 is the better choice, thanks to its flat curve and sealed ear cups.
The design suggests yes. It ships with interchangeable leather and suede ear cushions plus a leather headband, which lets you change the feel and seal when a session runs long. That is a design detail, not a guarantee — but it is the right detail to have.
