If you want a self-contained gaming headset with haptic-style 4D audio and an integrated boom mic, choose Mad Catz F.R.E.Q.4D; if you need a tiny adapter that adds a working 3.5mm headset port to a Windows PC, choose JSAUX USB. That is the whole decision in one line. If you were hoping this page answers "best bluetooth headphones for swimming," I'll be straight with you: neither of these is a swim product. But the question of how a Windows PC actually talks to a headset runs through both, so let's treat this as the practical, PC-first comparison it is.
• Mad Catz F.R.E.Q.4D — biggest strength: a complete, ready-to-wear over-ear headset with 50mm drivers, ViviTouch 4D sensory audio and a mic built into the earcup, so everything you need for voice chat is on your head already.
• Mad Catz F.R.E.Q.4D — biggest trade-off: it is a wired 3.5mm headset, so it depends on your PC (or adapter) actually having a working headset jack, and its 1.1 lb frame is on the heavier side for all-day wear.
• JSAUX USB — biggest strength: plug-and-play USB sound card that adds a TRRS 3.5mm port to a PC with no drivers, no external power, and a braided jacket that should outlast cheap plastic adapters.
• JSAUX USB — biggest trade-off: it is an adapter, not a headset — no drivers of its own, no microphone, and no sound at all until you plug a compatible TRRS headset into it.
• Who each pick is for: Mad Catz F.R.E.Q.4D for the gamer who wants one cable and instant voice chat; JSAUX USB for the PC owner whose jack is dead, missing, or noisy and who already owns a good wired headset.
The F.R.E.Q.4D is built around one idea: make game audio feel physical. ViviTouch 4D technology is the headline — it layers a sensory, vibration-like dimension onto the sound so explosions and impacts land with more presence than plain stereo. The 50mm dynamic drivers are oversize for a gaming headset, and Mad Catz pairs them with a 32 ohm impedance rating and a 20Hz–20kHz frequency range. That impedance figure matters: 32 ohms is easy to drive, which is why this headset is designed to run straight off a 3.5mm jack on a PC, Mac or smart device without a dedicated amp.
Then there's the practical side. The microphone lives in the earcup with a mute control, so you are not hunting for a boom arm or a separate desktop mic — you mute, you talk, you game. Mad Catz also claims tough-but-lightweight construction aimed at surviving LAN tournaments, a padded adjustable headrail for a wide range of head sizes, and GameSmart technology for quicker setup across devices. The enclosure is plastic, the ear placement is over-ear, and noise control is sound isolation rather than active cancellation.
JSAUX USB: Who It's For
The JSAUX USB adapter solves a very specific, very common problem: your PC's audio situation is broken, missing, or just not good enough, and you already own a wired headset you like. It converts a USB-A port into a 3.5mm TRRS jack, supporting both stereo listening and microphone input in one connection — so a single TRRS headset gives you sound and voice on a machine that otherwise couldn't take it.
The spec sheet is refreshingly honest about what it is. Plug and play, no drivers, no apps, USB bus-powered, recognized by the system in seconds — and small enough at 18cm to live in a pocket or a laptop bag. On the audio side, JSAUX rates the DAC sampling at 48kHz/16bit with a maximum sample rate of 96kHz, and describes a smart sound chip for high-speed decoding, low noise and high interference suppression. The housing is aluminum and the cable is nylon braided, which is a meaningful durability upgrade over the plastic-casing adapters that tend to fail at the strain relief.
Compatibility is broad: Windows 10/8.1/8/7/Vista/XP, Mac OS X, Linux, Chromebook, Surface 3 Pro, Raspberry Pi, PS4 and Android earphones. But the fine print is where buyers get burned, so read it twice. It needs a TRRS 4-pole headset — not TS or TRS microphones, and not headsets with separate headphone and mic plugs. Apple EarPods with a 3.5mm plug are explicitly not supported for mic use. PS3 won't work because its USB port doesn't carry audio. On PS4 Pro you should use the rear USB port.
Who should buy it: anyone on Windows (or Linux/Mac) who needs to resurrect a 3.5mm headset, replace a failed sound card, or add a headphone jack to a device that lacks one. Who should skip it: people with dual-plug headsets, anyone expecting it to be a headset rather than an adapter, and PS3 owners.
• Best for a complete, out-of-the-box gaming setup → Mad Catz F.R.E.Q.4D. Headphones, mic and mute are all included; nothing else to buy.
• Best for fixing a PC with no working audio jack → JSAUX USB. It creates the headset port your computer is missing.
• Best for immersive, physical-feeling game audio → Mad Catz F.R.E.Q.4D. The 50mm drivers and ViviTouch 4D effect are the entire point of the product.
• Best for portability and forget-it's-there convenience → JSAUX USB. At 0.01 kg and 18cm, it disappears into a bag; the F.R.E.Q.4D is 1.1 lb of over-ear hardware.
• Best for use with a headset you already love → JSAUX USB. It adapts rather than replaces.
• Best for long-session comfort → JSAUX USB, indirectly. The adapter adds no weight; the F.R.E.Q.4D is heavier and suited to shorter, more intense sessions.
• Best for voice chat clarity on a desktop → Mad Catz F.R.E.Q.4D. A dedicated earcup mic with mute beats routing a headset through an adapter.
• Best for broad OS flexibility → JSAUX USB. Windows, Mac, Linux, Chromebook, Raspberry Pi, PS4 — the adapter list is longer than the headset's.
If I had to pick one for a Windows PC today, I'd buy the Mad Catz F.R.E.Q.4D — assuming my PC has a working 3.5mm headset jack. It's the complete package: big drivers, the 4D effect, and a mic with mute, all in one wired connection that needs no setup. I'd only switch to the JSAUX USB if my jack were dead or missing, or if I already owned a TRRS headset I loved and just needed a reliable way to connect it. And to close the loop on that swim comparison: neither is a swim product — if you're actually shopping for the best gaming headphones for swimming, best bluetooth headphones for swimming, or wireless earbuds for swimming, look at fully waterproof, wireless designs instead. These two are desk-and-couch tools.
FAQ
how to connect headphones to windows pc
how to connect headphones to pc windows 10
On Windows 10, connect via the 3.5mm jack or the JSAUX USB adapter, then open the sound settings and set the correct device as your default output. JSAUX notes that for some computers you double-click the sound icon in the control panel and select the USB audio device, and you can raise the sampling rate in the device's Advanced properties.
how can i connect my headphones to my pc
Check the plug first. A single TRRS 4-pole plug works with the JSAUX USB adapter (and with a PC headset jack); a headset with separate headphone and mic plugs will not work with that adapter. The F.R.E.Q.4D connects directly by its 3.5mm jack on a compatible PC, Mac or smart device.
how to use headphones on pc
For the F.R.E.Q.4D, plug in and you're done — the mic and mute are on the earcup. For the JSAUX USB, the adapter is plug-and-play with no drivers or external power; just make sure you're using a TRRS headset, avoid PS3 (its USB port carries no audio), and on PS4 Pro use the rear USB port.
