How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the smallest, most travel-friendly way to keep a wired 3.5mm headphone and a charger running off one USB-C port, choose CableCreation USB C; if you need the higher-resolution DAC spec for serious hi-res headphone listening while you charge, choose JSAUX 2.
• CableCreation USB C — biggest strength: A tiny 1.94 x 0.5 x 0.35 inch no-cable dongle that splits one Type-C port into a 3.5mm audio jack plus 60W PD charging, with a DAC rated for 44.1/48/96 kHz sample rates at 16/24/32-bit.
• CableCreation USB C — biggest trade-off: The 3.5mm side is CTIA-only, so OMTP headphones can distort or lose the mic, it does not do data transfer, and it won't fit phone cases thicker than 2.8mm.
• JSAUX 2 — biggest strength: A Hi-Res DAC chip rated up to 32-bit/384kHz, which is a much higher decoding ceiling than the CableCreation adapter reaches on paper.
• JSAUX 2 — biggest trade-off: It is a corded design with a transparent case and braided cable, so it takes up more room than the CableCreation dongle, and QC charging may not work on every phone.
• Who each pick is for: CableCreation for minimalists, travelers and car-AUX users who want the smallest possible plug-and-go adapter; JSAUX 2 for listeners who care about the DAC spec and want the nicer cable.
The CableCreation USB C adapter is a 2-in-1 splitter: it takes your single Type-C port and gives you back a 3.5mm audio jack and a USB-C PD charging port at the same time. That "play while charging" trick is the whole point. If you watch movies on a phone, take long calls, or drive with a 3.5mm AUX cable in the car, you no longer have to choose between power and sound.
The audio spec is where it matters for hi-res headphones. The built-in DAC supports 44.1, 48 and 96 kHz sample rates at 16, 24 or 32-bit, and the ADC input runs at 48 kHz / 16-bit. In plain terms, that covers CD-quality and better-than-CD material, which is exactly the range most hi-res streaming tiers and local hi-res files live in. There's also a smart chipset for volume control and call answering on compatible devices, and the whole thing weighs about 0.01 kg with a glossy Space Gray finish.
JSAUX 2: Who It's For
The JSAUX 2 does the same core job — one USB-C port becomes a 3.5mm jack plus a USB-C PD charging port — but it leans harder into audio quality. Its Hi-Res DAC chip is rated up to 32-bit/384kHz, and JSAUX frames that directly as an upgrade over the 16-bit/48kHz found in other adapters. If you're chasing hi-res headphone listening and you want the adapter's decoding ceiling to sit well above the source material rather than right at it, that number is the headline.
The build is the other half of the story. The JSAUX 2 uses a transparent case that shows off the internal chip, an aluminum alloy exterior, and a bend-resistant braided cord. So instead of a rigid dongle hanging off your phone, you get a short cable — more flexible at the port, generally easier on the connector over time, and visibly more premium in the hand.
Charging is handled by PD3.0 and QC3.0 support with a maximum output of 60W, matching the CableCreation adapter's 60W ceiling. JSAUX notes QC may not work on some phones, so PD is the safer expectation. Compatibility is broad: iPhone 15/16/17 Pro Max Plus Air, Galaxy S24/S23/S22/S21 families, iPad Pro/Air/Mini, MacBook, Pixel 7/6 XL, OnePlus Nord and more. I'd point this one at the listener who treats the adapter as part of their audio chain, wants the higher DAC spec, and doesn't mind a short cable instead of a bare plug.
• Best for the highest-resolution decoding spec → JSAUX 2. Its DAC is rated to 32-bit/384kHz versus 44.1/48/96 kHz on the CableCreation adapter.
• Best for the smallest possible footprint → CableCreation USB C. At 1.94 x 0.5 x 0.35 inches and 0.01 kg, it's the one that disappears in a pocket.
• Best for charging speed → a tie. Both are rated for 60W PD output, so neither pulls ahead on raw power delivery.
• Best for durability and cable feel → JSAUX 2. Aluminum alloy plus a bend-resistant braided cord beats a rigid glossy dongle for long-term wear at the port.
• Best for car AUX and quick plug-in use → CableCreation USB C. The no-cable design plugs straight into a 3.5mm AUX jack without a dangling loop.
• Best for headphone-standard safety → JSAUX 2. CableCreation is CTIA-only and warns about OMTP distortion; JSAUX doesn't carry that same caveat in its spec.
• Best for thin cases and tight fit → check yours. CableCreation explicitly won't fit cases thicker than 2.8mm, which rules out a lot of rugged cases.
• Best for hi-res headphones specifically → JSAUX 2. If your headphones and source files can resolve above 96 kHz, the CableCreation DAC becomes the bottleneck.
For hi-res headphone listening, I would buy the JSAUX 2. The reason is simple and it's in the specs: a 32-bit/384kHz DAC gives your headphones far more headroom than a 96 kHz ceiling, and the aluminum-and-braided build is the kind of thing I'd rather have hanging off a phone port every day. I'd only switch to the CableCreation USB C if size is the deciding factor — for a car, a travel kit, or a case-free phone where a bare dongle is genuinely more convenient. Both deliver 60W PD charging, so that part is a wash in my opinion.
what is hi res headphones
Hi-res headphones are headphones meant to reproduce high-resolution audio — digital material with more detail than standard CD quality. In practice, that means the headphones and the DAC feeding them both need to handle higher sample rates and bit depths, which is exactly why the DAC spec on an adapter like these two matters.
what is hi res audio headphones
It's the same idea phrased the other way: headphones used for hi-res audio. High-resolution audio generally refers to files and streams above CD-level quality, and a hi-res-capable headphone is one that can resolve that extra detail. The adapter in the chain has to keep up, which is where a 32-bit/384kHz DAC like the JSAUX 2's has an edge over a 96 kHz one.
what are hi res headphones
They're headphones built for high-resolution playback rather than casual listening. The key spec to watch is the DAC and sample-rate support between your phone and the headphones — the CableCreation adapter handles 44.1/48/96 kHz at up to 32-bit, while the JSAUX 2 is rated to 32-bit/384kHz.
which headphones support hi res lossless
That depends on the headphones, not the adapter — the adapter just needs to pass the signal without capping it. If your headphones can resolve above 96 kHz, the JSAUX 2's 32-bit/384kHz DAC won't be the limiting factor, whereas the CableCreation adapter tops out at 96 kHz. Check your headphone's own spec sheet first, then match the adapter to it.
