How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an all-in-one stereo headset with a boom mic, inline volume and mute, and a plug-and-play USB connection, choose Cyber Acoustics AC-5014; if you need to stretch an existing 3.5mm stereo signal across a long distance — say, from a TV or stereo to a chair across the room — choose VIOY Headphone Extension Cable.
• Cyber Acoustics AC-5014 — biggest strength: It's a complete wired stereo headset. You get the drivers, the padded over-ear cups, the adjustable boom mic, and inline volume plus mic-mute, all in one USB-C device that needs no setup.
• Cyber Acoustics AC-5014 — biggest trade-off: It only works with devices that accept its USB connection, and the mic is unidirectional, so it favors one speaking direction rather than room-wide pickup. The cable is 6 ft — generous, but fixed.
• VIOY Headphone Extension Cable — biggest strength: It's 100 ft of braided 3.5mm male-to-female cable built to carry a stereo signal a long way with minimal loss, and it won't tangle.
• VIOY Headphone Extension Cable — biggest trade-off: It's a passive TRS cable, not a headset. It won't work with inline volume controls, and on TRRS (4-pole) headphones you'll get audio but no mic.
• Who the Cyber Acoustics AC-5014 is for: Anyone who needs to talk and listen — students, teachers, remote workers, call handlers — on a computer, tablet or phone with a USB connection.
• Who the VIOY Headphone Extension Cable is for: Anyone who already owns good 3.5mm headphones or speakers and just needs more reach between the source and their ears.
The AC-5014 is a stereo headset first and a microphone second, and that order matters. The earcups are over-ear and rounded, padded with leatherette, and the headband is adjustable, so the design is aimed at long sittings rather than quick calls. The drivers are dynamic, rated 32 ohm with a 20 Hz–20,000 Hz frequency range — a full-range stereo spec that covers speech and music alike. If you're listening to a lecture, a lesson, a podcast or a call, that's the range doing the work.
What really separates it is the mic and control layout. The boom mic is unidirectional, which means it picks up sound mainly from the direction it's pointed. That's a deliberate choice: it cuts down ambient noise while you speak or record, and it's why this kind of headset shows up in classrooms and home-study setups where you don't want every background sound on the line. The boom rotates, so you can wear the mic on the left or the right. Volume and mic-mute sit inline on the cable, within easy reach.
Build is clearly aimed at hard use. The braided TuffCord is designed to resist tangling and chewing, the 3.5mm-style stress points get a steel rod, and the leatherette earpads are double-stitched and easy to wipe clean. The headband is built to survive rolling, twisting and bending. Cyber Acoustics also notes the plastic includes 60% recycled material, and there's a one-year warranty plus US-based support.
Buy it if you need one device that handles both your voice and your audio on a PC, Mac, tablet or phone, and you want it to survive being tossed in a bag. Skip it if your source only has a 3.5mm jack, if you need wireless freedom, or if you already own headphones you love and only lack cable length.
The VIOY cable solves one problem and solves it at scale: distance. It's 100 ft long, male-to-female, with a 3.5mm TRS connection at both ends. If your headphones or speakers are tethered to a source that's nowhere near your seat — a TV across the room, a stereo on a shelf, a phone on a desk — this is the bridge.
The build is more serious than a generic aux cord. The core is high-purity copper with dual shielding, which is the part that matters over 100 ft: shielding is what keeps static and interference out of a run that long, and copper is what keeps signal loss minimal. The connector is 24k gold-plated, and the shell is solid copper, which helps with conductivity and resists oxidation over time. The jacket is a cotton-mesh braid over TPE, rated to withstand a 15,000+ lifecycle test. The 3-pin design and the slim plug mean you can usually connect without pulling your phone or tablet out of its case.
The catch is in the connector type, and it's worth reading twice. This is TRS — three conductors — so it carries stereo audio only. It does not work with inline volume controls on headphones. And if your headphones are TRRS (four-pole, the kind with a built-in mic), you'll hear audio fine but the microphone won't work through this cable.
Buy it if you have 3.5mm stereo gear and a long-distance gap to close, indoors or out. Skip it if you need a microphone, if your headphones rely on an inline remote, or if your devices are USB-only.
• Best for talking and listening at once → Cyber Acoustics AC-5014. It has a real unidirectional boom mic; the VIOY cable carries no mic signal on TRS at all.
• Best for long cable runs → VIOY Headphone Extension Cable. 100 ft versus the AC-5014's fixed 6 ft.
• Best for USB-C, PC, Mac and tablet setups → Cyber Acoustics AC-5014. Plug in and play, no installation.
• Best for keeping your existing 3.5mm headphones → VIOY Headphone Extension Cable. It extends what you already own instead of replacing it.
• Best for volume and mute control at your fingertips → Cyber Acoustics AC-5014. Inline controls are built in. The VIOY cable explicitly won't pass inline volume control through.
• Best for classroom, study and shared-space use → Cyber Acoustics AC-5014. The unidirectional mic, cleanable pads, chew-resistant cord and durable headband are designed around exactly that environment.
• Best for TV, stereo, car and home-theater reach → VIOY Headphone Extension Cable. It's built for audio transmission between a 3.5mm source and speakers or headphones.
• Best for stereo audio quality over distance → VIOY Headphone Extension Cable. Dual shielding and a pure copper core are the reasons a 100 ft run stays clean.
• If you own neither and need to communicate → Cyber Acoustics AC-5014. If you own good headphones and just need length → VIOY Headphone Extension Cable.
In my opinion, most people searching these two names are really asking two different questions, so I'd split it. If your goal is to talk and listen — classes, calls, remote work, study — I'd buy the Cyber Acoustics AC-5014. It's the complete tool: stereo drivers, a directional boom mic, inline controls, and a build meant to survive daily abuse.
If your goal is simply to move a stereo signal across a room without losing quality, I'd buy the VIOY Headphone Extension Cable. Just be honest about your headphones first: if they're TRRS or you depend on an inline remote, this cable will leave those features behind.
FAQ
Neither product here is wireless, so there's nothing to pair. The Cyber Acoustics AC-5014 connects by plugging its USB cable directly into a compatible PC, Mac, tablet or phone — no installation needed. The VIOY cable doesn't connect to anything wirelessly either; it physically links a 3.5mm source to 3.5mm headphones or speakers.
how to use wireless headphones
If you're actually looking for wireless operation, neither of these fits. The AC-5014 is a wired USB headset with a 6 ft cable, and the VIOY product is a 100 ft passive 3.5mm extension cable. Both are wired by design — that's the trade-off for zero pairing, zero charging and no latency.
how to wireless headphones work
Since both products are wired, the relevant question is how they carry audio. The AC-5014 sends digital audio over USB and outputs stereo through its dynamic drivers and onboard controls. The VIOY cable carries analog stereo over a 3-pin TRS connection with dual shielding — audio only, no microphone and no inline volume support.
They're not substitutes. The AC-5014 is a full stereo headset with a microphone, inline volume and mute, and a durable build, so it replaces your headphones and mic entirely. The VIOY cable adds no audio hardware — it only adds length to gear you already have. Decide whether you need a headset or just more cable. For current pricing on either, check the price on Amazon.
