We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a compact, no-cable adapter that keeps a low profile in your pocket and splits one USB-C port into audio plus PD 60W charging, choose JSAUX USB C; if you need a braided-cable dongle with a dedicated DAC chip rated for 24bit/96kHz Hi-Fi audio and the broadest Android compatibility list here, choose Eusbote Type C.
• JSAUX USB C — biggest strength: a slim, glossy, plug-and-play splitter (PD 60W + 3.5mm) that adds almost nothing to your pocket, with inline headphone controls supported.
• JSAUX USB C — biggest trade-off: compatibility is broad but not universal (no support for all OnePlus and Pixel models, and no inline volume control on Apple EarPods).
• Eusbote Type C — biggest strength: a built-in DAC chip tuned for 24bit/96kHz stereo playback and HD voice with no current noise, plus a huge Samsung/Pixel compatibility list.
• Eusbote Type C — biggest trade-off: no data transfer, and it's a fixed 18cm cable rather than a stubby adapter, so it dangles more.
• Who each pick is for: JSAUX for minimalists who want the smallest possible audio-plus-charge splitter; Eusbote for listeners who prioritize audio quality and own a newer Samsung or Pixel phone.
The JSAUX USB C adapter is built around one idea: take the single USB-C port on your phone, tablet or laptop and split it into two useful things at once — a PD-compatible charging port and a 3.5mm audio jack. That means you can play a game, take a call, or watch a film while the device is still fast-charging. It supports up to PD 60W charging, and JSAUX notes that you'll get the fastest speeds with a PD20W-or-higher wall charger, since QC may not be supported on some phones.
What I like about the design is how little space it takes up. The item measures roughly 11 x 0.15 x 0.15 inches and weighs about 0.03 kg — it's essentially a slim stick with a glossy red finish. There are no drivers to install, and it's plug-and-play anywhere. It supports inline headphone controls on the cable, which is a genuinely useful detail for anyone who takes calls on wired earbuds. Two caveats worth knowing: it doesn't support inline volume control on Apple's EarPods, and if your music pauses after you unplug power, that's the main control chip restarting — just press play again.
This is the adapter I'd point a commuter or traveler toward if they want the smallest possible solution and use a mainstream USB-C phone like an iPhone 15/16 series, a Galaxy S20 through S24, a Note, an iPad Pro, or a Huawei Mate/P series. I'd steer you elsewhere if you're on a OnePlus or a Pixel model that JSAUX lists as unsupported, or if you rely on Apple EarPod inline volume buttons.
The Eusbote Type C adapter does the same core job — one USB-C port becomes a PD charging port plus a 3.5mm jack so you can listen and fast-charge at the same time — but it leans harder into audio quality. Inside is a high-quality DAC chip rated for 24bit/96kHz stereo, which Eusbote positions as stable, lossless transmission with HD voice support and no current noise. It also handles both CTIA and OMTP headphone standards, so older wired headsets are less likely to misbehave. Like the JSAUX, it supports up to 60W PD charging, and Eusbote recommends a PD wall charger for the best speed since QC may not work on some newer phones.
The physical design is the other big difference. Eusbote uses a premium aluminum alloy connector shell with a nylon-braided cable in purple, and it's a fixed 18cm length — short enough to carry easily, long enough to give your phone a little breathing room on a desk or in a bag. It's plug-and-play with no drivers or apps, and it supports volume control. One limitation to be clear about: it does not support data transfer, so this is strictly an audio-and-power accessory.
I'd recommend this one for someone who cares most about sound — a music listener, a gamer, or anyone taking long calls — and who owns a device on Eusbote's very long compatibility list, especially the newer Galaxy S-series, A-series, Z Flip/Fold, and the Pixel 10/9/8/7/6/5 families. Skip it if you need data sync, or if you want the absolute smallest adapter and don't want any cable at all.
Side-by-Side: Which Should You Choose?
• Best for audio quality → Eusbote Type C: the dedicated DAC chip with 24bit/96kHz stereo and no-current-noise design is the clear pick for sound-first buyers.
• Best for the broadest Android compatibility → Eusbote Type C: its list covers a huge range of Samsung, Pixel, Z Flip/Fold and A-series models.
• Best for mainstream iPhone and Galaxy users who want a simple splitter → JSAUX USB C: it works across iPhone 15/16 series, Galaxy S20–S24, Note, iPad Pro and Huawei devices.
• Best for durability feel → Eusbote Type C: aluminum alloy shell plus nylon-braided cable reads as the more rugged build.
• Best for inline headphone controls → JSAUX USB C: it explicitly supports inline controls (just not Apple EarPod volume).
• Best if you need data transfer → neither: the Eusbote explicitly skips data, and the JSAUX is an audio-and-charge splitter, so plan around that.
• Best for charging flexibility → a tie: both support up to PD 60W and both want a PD20W-plus or PD wall charger for top speed.
In my opinion, I'd buy the Eusbote Type C if audio quality is what matters to you. The DAC chip rated for 24bit/96kHz stereo, the CTIA/OMTP support, and the aluminum-and-nylon build make it the more compelling pick for listening, gaming and calls — and its compatibility list is enormous if you're on a modern Samsung or Pixel. I'd choose the JSAUX USB C instead if you want the smallest, simplest adapter and you're on a mainstream iPhone, Galaxy or Huawei device. Both fast-charge at up to PD 60W, so the real decision is sound and build versus size and simplicity.
how to fast charge bose headphones
This page is about USB-C to 3.5mm audio-and-charge adapters, not about charging Bose headphones directly, so the honest answer is that these adapters charge your phone while you listen — not the headphones. For the phone side, both adapters support up to PD 60W, and both makers recommend a PD20W-or-higher or PD wall charger, since QC may not be supported on some phones.
how to charge headphones faster
If you mean the headphones themselves, that depends on the headphone's own charging spec, which isn't part of these adapters. What these dongles do is keep your phone topped up at up to 60W PD while audio plays. Use a PD charger rated PD20W or higher, and skip Quick Charge on phones where it isn't supported.
how to charge headphones
For wired headphones via a 3.5mm jack, there's nothing to charge — they draw no power. These adapters exist to give a phone without a headphone jack a 3.5mm port while still letting you charge the phone through the same USB-C connection. Plug the adapter in, connect your headphones, and connect a PD charger to the adapter's charging port.
is fast charging bad for headphones
No — fast charging here applies to your phone, not your headphones. Both adapters cap at PD 60W, and Eusbote notes its chip is designed to stabilize charging voltage and current to protect your device. The headphones just receive an audio signal, so charging speed doesn't affect them.
