If you want a single TRRS jack that handles headset mic and stereo output over a classic USB-A port with a braided, metal-bodied build, choose JSAUX USB; if you need separate headphone and microphone jacks on a USB-C connection for a modern laptop or phone, choose biaze USB C.
• JSAUX USB — biggest strength: one TRRS 4-pole jack that carries both stereo listening and mic input, with a 48kHz@16bit DAC sampling rate, an aluminum housing and a nylon-braided jacket built to outlast plastic-cased adapters.
• JSAUX USB — biggest trade-off: it's USB-A, it's unidirectional (audio only flows from USB to the 3.5mm port, never the reverse), it won't work with TS/TRS mics or headsets with separate headphone and mic plugs, and Apple EarPods' mic isn't supported.
• biaze USB C — biggest strength: two dedicated 3.5mm jacks — one for a mono microphone, one for speaker/headphone output — so dual-plug headsets and standalone mics connect natively over USB-C.
• biaze USB C — biggest trade-off: ABS plastic construction, a shorter 18-month warranty, and the same 48kHz/16bit ceiling without JSAUX's metal-and-braid durability story.
• Who each pick is for: JSAUX USB suits desktop and PS4/PS5 owners with a 3.5mm TRRS headset and an open USB-A port; biaze USB C suits laptop, tablet and USB-C device owners who need separate mic and headphone sockets.
The JSAUX adapter solves a very specific, very common problem: your computer's 3.5mm port died, or it never had a proper one, and you want your existing TRRS headset to keep working. It takes a USB-A port and turns it into a 4-pole CTIA/OMP 3.5mm jack that carries stereo output and microphone input on the same connector. That single-jack design is the whole point — one cable, no dongle chain, no confusion about which plug goes where.
What it does best is get out of the way. There are no drivers, no apps, no external power. The system recognizes it in seconds because it's USB bus-powered, and the box includes an 18cm USB-A to 3.5mm cable that slips into a pocket for the office, a conference room, or a hotel desk. JSAUX rates the DAC at 48kHz@16bit with a smart sound chip for signal decoding, and the company's pitch is low noise and strong interference suppression — the kind of thing that matters when your mic is feeding a call and you don't want hiss underneath your voice.
The build is where JSAUX separates itself on paper. Aluminum housing, nylon-braided jacket, explicitly positioned as more durable than plastic-casing, PVC-cable adapters. If your last cheap adapter died at the strain relief, that's the argument.
biaze USB C: Who It's For
The biaze adapter attacks the same problem from the other end of the cable. It's USB-C in, and it splits into two 3.5mm jacks: a mono microphone input and a speaker/headphone output. That's the design decision that defines it. If you own a dual-plug headset, a standalone desktop mic, or a small speaker that wants its own socket, biaze gives you a real port for each instead of forcing everything through one TRRS ring.
It's aimed squarely at the modern device set: laptops, desktops, tablets, USB-C phones. biaze lists Windows 10/8.1/8/7/Vista/XP, Mac OS X, Linux, Google Chromebook, Windows Surface 3 Pro, Raspberry Pi, and PS4/PS5 as compatible, with CTIA-standard jacks and Android earphone support. The stated use cases are the ones people actually have — meetings, gaming, streaming, online classes, music, voice chat — plus support for inline controls on your headset cable.
Audio-wise, biaze uses a built-in DAC chip rated at 16bit/48kHz with noise reduction, and the pitch is clear calls and stable performance at home, in the office, or on the road. Plug and play, no drivers, no external power.
The trade-offs are honest ones. The housing is durable ABS plastic, not metal — fine for a bag or a desk drawer, but it won't feel like the JSAUX unit. The channel configuration is listed as 2 rather than 4. And the warranty is stated at 18 months, which tells you something about how the brand expects the part to age.
Side-by-Side: Which Should You Choose?
• Best for a single TRRS headset → JSAUX USB. One 4-pole jack handles listening and speaking together.
• Best for a dual-plug headset or separate mic → biaze USB C. Dedicated mono mic input plus headphone output.
• Best for modern laptops, tablets and USB-C phones → biaze USB C. USB-C is the native port there.
• Best for desktops and consoles with USB-A → JSAUX USB. It's built for the older, bigger port.
• Best for long-term durability → JSAUX USB. Aluminum housing and nylon-braided jacket beat ABS plastic.
• Best for working with inline headset controls → biaze USB C. It explicitly supports inline controls.
• Best for a failed 3.5mm port on a USB-C machine → biaze USB C. It restores the port and adds a second one.
• Best for PS4 Pro → JSAUX USB, using a rear USB port; for PS5 either adapter is listed as compatible.
In my opinion, most people shopping this comparison should buy the JSAUX USB. The aluminum housing and nylon-braided cable are the difference between an adapter that survives a year in a laptop bag and one that doesn't, and a single TRRS jack covers the headset most people already own. I'd only steer you to the biaze USB C if your device is USB-C-only or you genuinely need separate microphone and headphone sockets — in that case its dual-jack layout is the feature that matters and the plastic body is a fair trade. Check the current price on Amazon before you commit, since these are inexpensive parts and the gap is rarely worth agonizing over.
JSAUX USB. Its 4-pole TRRS jack carries both stereo audio and mic input on that single connector, which is exactly what a one-plug headset needs. The biaze unit splits mic and output into two separate jacks.
Yes. biaze extends a 3.5mm mono microphone input and a speaker-headphone output through the USB-C port, so dual-plug headsets and small speakers connect properly. A single-TRRS design like JSAUX's can't do that.
On paper, JSAUX USB. It uses an aluminum housing with a nylon-braided jacket, which the brand positions as more durable than plastic casing and PVC cable. biaze uses durable ABS plastic and lists an 18-month warranty.
Only the biaze USB C, because it's a USB-C device. The JSAUX adapter terminates in USB-A, so you'd need a USB-A port or an additional adapter to use it there.
No. Both are plug and play with no drivers or external power required. With some computers you may need to select the USB audio device as your default output in the sound control panel.
