How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired headset with a boom mic for calls and classes, choose Spracht ZUM350M; if you need a protective headband cover for your Audio Technica ATH M-series headphones, choose Voarmaks M50X.
• Spracht ZUM350M — biggest strength: A complete, ready-to-use over-ear headset with an inline microphone, passive noise cancellation, and both 3.5mm and 2.5mm connectivity for tablets, phones, and computers.
• Spracht ZUM350M — biggest trade-off: It is a wired headset built around communication, not a hi-fi listening product, and the "Bluetooth" field in its specs sits awkwardly next to the wired jack, so buyers should treat it as a corded device first.
• Voarmaks M50X — biggest strength: A dual-layer neoprene headband cover with a wrap-around tape layer that protects and cushions the headband of Audio Technica M-series headphones.
• Voarmaks M50X — biggest trade-off: It is an accessory, not a pair of headphones — without a compatible ATH M-series headset, it has nothing to attach to.
• Who the Spracht is for: Anyone who needs one headset for calls, meetings, and everyday listening on multiple devices.
• Who the Voarmaks is for: Existing Audio Technica M50/M50X/M40X/M30 owners who want to protect or refresh their headband.
The Spracht ZUM350M is a wired over-ear headset with a microphone, and that single sentence tells you most of what you need to know. It's built for people who spend their day talking — on video calls, in online classes, on support lines — and who want one device that moves between a tablet, a smartphone, and a computer without drama. The included 2.5mm adapter is the detail that makes that promise real: plenty of headsets assume a standard 3.5mm socket, and the adapter covers the devices that don't.
On the audio side, the ZUM350M uses a dynamic driver with a 20Hz–20,000Hz frequency range and a 32-ohm impedance. That impedance figure matters more than it looks. At 32 ohms, the headset is easy to drive — a phone, tablet, or laptop headphone jack has no trouble pushing it to a usable volume. You are not buying an amp to go with this thing. The sound signature is aimed at speech intelligibility, which is exactly what you want when the priority is hearing other people clearly and being heard clearly in return.
The over-ear design and leather enclosure material are worth calling out for comfort during long sessions. Over-ear cups sit around the ear rather than pressing on it, and leather tends to feel warmer and more sealed than fabric. The noise control is passive, meaning the physical seal of the cups does the blocking rather than any electronics or battery. That is a real limitation and a real advantage at the same time: no charging, no firmware, no dead battery in the middle of a meeting — but also no active hiss-cancelling for airplane engines or open-plan offices.
Voarmaks M50X: Who It's For
The Voarmaks M50X is not a headphone. It's a headband cover, and understanding that distinction is the entire point of this section. If you already own an Audio Technica ATH M-series headphone, this is the kind of small purchase that quietly extends the life of something you already like.
The compatibility list is specific: ATH M50, M50X, M50XWH, M50XBT, M50XBT2, and M50S/LE. That's a deliberately narrow list, and it's why "universal" here means "fits the ATH M-series range" rather than "fits everything." If your headphones aren't on that list, this cover isn't for you, no matter how good it looks.
What makes it more than a cosmetic sleeve is the dual-layer construction. Standard headband covers are single-layer fabric or foam. Voarmaks adds a wrap-around tape layer that traps existing wear and debris in place without adhesive — so no glue residue on your headband, which is the failure mode that ruins cheaper covers. The outer layer is stretchable neoprene, a material that molds to the headband's curve instead of bunching at the ends. The result is a snug fit that stays put.
The secondary benefit is comfort. The listing describes added soft padding for extended listening sessions, and that tracks with the dual-layer build — you're effectively adding a cushion between the headband and the top of your head. For anyone who has ever felt the stock M-series headband dig in after two hours, that's a meaningful upgrade. It's also available in a range of colors if you want to change how your headphones look, and the item weight of 39 grams confirms it won't add noticeable heft. Voarmaks backs it with a warranty, which is a reasonable signal for a low-cost accessory. The item dimensions (9.45 x 3.66 x 0.1 inches) describe a thin, flat strip — that's the cover lying flat, not a bulky shell.
Who should skip it? Anyone who doesn't own ATH M-series headphones, and anyone hoping this somehow upgrades sound quality. It doesn't touch the drivers. It protects and cushions the headband, full stop.
Side-by-Side: Which Should You Choose?
• Best for calls and meetings → Spracht ZUM350M. It has a built-in microphone and is designed around voice communication.
• Best for device flexibility → Spracht ZUM350M. The 3.5mm jack plus 2.5mm adapter covers tablets, smartphones, and computers.
• Best for long-session comfort → Voarmaks M50X. The dual-layer neoprene adds padding to an existing headband.
• Best for plug-and-play simplicity → Spracht ZUM350M. Passive noise cancellation means no battery, no charging, no pairing.
• Best for cleaning up a worn headband → Voarmaks M50X. The tape layer traps existing wear and debris without glue.
• Best if you're starting from zero → Spracht ZUM350M. The Voarmaks is useless unless you already own compatible headphones.
• Best for personalizing your look → Voarmaks M50X. It comes in multiple color options; the Spracht comes in black.
These two products barely compete — they solve completely different problems, and the "versus" framing only makes sense if you're deciding where your money goes first. In my opinion, if you need a headset right now for calls, classes, or remote work, buy the Spracht ZUM350M. It's a self-contained, wired, microphone-equipped over-ear headset that works across your devices without a battery or an app. If you already own an Audio Technica M-series headphone and the headband is showing its age, buy the Voarmaks M50X — it's a cheap, glue-free way to add comfort and protect your investment. And if you're torn purely on budget, check the current price on Amazon before deciding; the two sit in very different spending brackets.
what is universal headphones
In the strict sense, "universal" headphones are ones designed to work across a wide range of devices rather than being locked to one brand or connector. The Spracht ZUM350M fits that idea: it's a wired headset that ships with both a 3.5mm jack and a 2.5mm adapter, so it can connect to tablets, smartphones, and computers. There's no single industry definition, though.
are headphones universal
No — most headphones are not truly universal. Connector type, impedance, and whether a microphone is included all determine what a headset will actually work with. The Spracht ZUM350M is close to universal for wired devices at 32-ohm impedance with both 3.5mm and 2.5mm options, but it won't cover every device or every use case. The Voarmaks M50X is a different kind of "universal": its compatibility is limited to specific Audio Technica ATH M-series models.
are gaming headphones universal
Not necessarily. Many gaming headsets rely on USB, proprietary wireless dongles, or console-specific connections, which limits how universal they are. A wired 3.5mm headset like the Spracht ZUM350M is more flexible because the jack works across phones, tablets, and computers — but if you need surround processing or console chat features, check compatibility before buying.
No, and most people won't. The Spracht ZUM350M is a complete headset for talking and everyday listening; the Voarmaks M50X is a protective cover that only fits Audio Technica ATH M-series headphones. They serve different owners with different needs, so buy the one that matches the problem you actually have.
