How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a simple, pocketable adapter that lets you plug a 3.5mm headphone jack into a USB-C phone while still topping up the battery, choose ehaon 2-in-1; if you need a splitter that feeds a USB-C headset its own digital audio path while pushing up to 60W of PD power into your device at the same time, choose JasRoum USB C Splitter.
• ehaon 2-in-1 — biggest strength: it does the classic two-jobs-at-once trick for 3.5mm wired headphones, turning one USB-C port into an audio jack plus a charging pass-through, with a 1-year warranty behind it.
• ehaon 2-in-1 — biggest trade-off: it is built around the older 3.5mm analog headphone world, so it is not the pick if your headphones are USB-C digital.
• JasRoum USB C Splitter — biggest strength: a true 1-in-2-out split with a dedicated 60W PD charging port and a separate digital audio port that relies on your headset's own built-in DAC chip.
• JasRoum USB C Splitter — biggest trade-off: it explicitly does not support analog headphones — if your headphones work with a simple passive adapter, they will not work here — and it is a compact short-cable dongle rather than a long cable.
• Who each pick is for: ehaon 2-in-1 for the 3.5mm wired-headphone user who wants a tiny white dongle; JasRoum for the USB-C headset user who wants fast charging and lossless digital audio at the same time.
The ehaon 2-in-1 is a USB-C to 3.5mm headphone adapter with fast charging baked in. That single sentence is basically its whole personality, and for a lot of people that is exactly what they need. It is a small white dongle — 5.11 x 1.81 x 0.39 inches and 1.76 ounces — with two ports, a USB Type-C connector, and compatibility listed across headphones, laptops, MP3 players, smartphones and speakers. It ships with no plug of its own, which makes sense: it draws power from whatever charger you already own.
What it does best is solve the everyday annoyance of a phone that has one USB-C port and no headphone jack. You plug the ehaon into the phone, plug your 3.5mm headphones into the adapter, and plug your charging cable into the same adapter. Music keeps playing while the battery climbs. For someone who takes calls on a wired headset during a long workday, or who listens to podcasts on a commute with the screen on, that simultaneous audio-and-charge behavior is the reason to buy it.
Who should buy it: anyone with 3.5mm wired headphones and a USB-C phone — a Galaxy S22/S23/S24 Ultra or Note 20, an iPhone 15/16 Pro/Max/Plus, or an iPad — who is tired of choosing between listening and charging. The 1-year warranty is a reasonable safety net for a small accessory.
JasRoum USB C Splitter: Who It's For
The JasRoum USB C Splitter is a different animal. It is a 1-in-2-out adapter: one USB-C plug goes into your device, and the other end splits into two dedicated ports — one for up to 60W PD fast charging and one for digital audio. Silver aluminum housing, white braided short cable, small enough to slip into a pocket. It carries a 24-month warranty and lifetime tech support, which is a longer commitment than most dongles bother with.
The headline feature is the 60W PD charging. That is enough to power phones, tablets, and even laptops, provided your charger and cable actually support PD 3.0 and 60W output — the real speed depends on your charger and your device's capabilities, so a weak charger will not magically become fast. The second port is for audio, and here the design is specific: it passes sound straight to USB-C headphones with a built-in DAC chip for lossless digital transmission. Crystal-clear calls, gaming audio, music — that is the pitch, and it is a genuinely different approach from an analog adapter.
The one thing you must check before buying is your headphone type. JasRoum states plainly that the splitter does not support analog audio headphones, typically older or budget models. Their test is simple: if your headphones work with a simple passive adapter, they are analog and will not work here. That single caveat is the whole buying decision.
Who should buy it: USB-C digital headset owners — iPhone 17/16/15 series, Galaxy S25/S24/S23 Ultra, Note 20, Pixel 10/9, iPad Pro/Air, MacBook, Tablet, Switch, Steam Deck, game consoles — who want to charge at up to 60W while listening. The short cable and fingerprint-resistant aluminum shell make it a tidy desk or travel companion.
Who should skip it: anyone with 3.5mm analog headphones, and anyone who needs a long cable run rather than a compact dongle.
Side-by-Side: Which Should You Choose?
• Best for USB-C digital headsets → JasRoum USB C Splitter. It is designed around your headset's own DAC chip.
• Best for charging while listening at higher wattage → JasRoum USB C Splitter, which advertises up to PD 60W.
• Best for a lightweight, familiar dongle → ehaon 2-in-1, at 1.76 ounces with a straightforward two-port layout.
• Best for laptop and tablet charging alongside audio → JasRoum USB C Splitter, since 60W PD reaches beyond phones.
• Best for color and build preference → ehaon 2-in-1 in white versus JasRoum in silver with an aluminum alloy shell and a short braided cable.
• Best warranty cushion → JasRoum USB C Splitter with its 24-month warranty, versus the 1-year warranty on the ehaon.
• Best for older or budget analog headphones → neither is guaranteed, but the ehaon is the only one of the two actually aimed at analog jacks.
In my opinion, the deciding question is not brand or build — it is what is on the end of your headphone cable. If you own USB-C headphones with a built-in DAC and you want to keep listening while charging at up to 60W, I would buy the JasRoum USB C Splitter. Its dedicated audio and PD charging ports, aluminum shell, short braided cable and 24-month warranty make it the more capable tool for that setup. If you are still on 3.5mm wired headphones, I would buy the ehaon 2-in-1 instead, because the JasRoum simply will not work with analog headphones. Match the adapter to your headset and you will be happy either way.
how to fast charge bose headphones
Check what the headphone end actually is first. If your Bose headphones terminate in a 3.5mm plug, the ehaon 2-in-1 is the one that fits, and charging speed comes from your own USB-C charger. If they are USB-C digital, the JasRoum splitter passes audio through and offers up to 60W PD charging — but you need a PD 3.0 charger and cable rated for 60W to see that speed.
how to charge headphones faster
Faster charging comes from the charger and cable, not the adapter alone. The JasRoum USB C Splitter advertises up to 60W PD, but it states plainly that actual speed depends on your charger and device capabilities, so pair it with a matching PD 3.0 charger. The ehaon 2-in-1 lists no wattage figure in its specifications, so treat it as a convenience pass-through rather than a high-wattage solution.
how to charge headphones
You need a path from a power source to the headphones. With the ehaon 2-in-1, you plug the dongle into your phone, your 3.5mm headphones into the adapter, and a charging cable into the second port so both happen at once. With the JasRoum splitter, one port handles up to 60W PD charging and the other handles digital audio, provided your headphones are USB-C with a built-in DAC chip.
is fast charging bad for headphones
Neither product's specifications indicate any risk to your headphones from fast charging. The JasRoum splitter separates the 60W PD charging port from the digital audio port, and its aluminum shell is described as aiding heat dissipation during high-speed charging. Charging speed ultimately depends on your charger and device, so follow your headphone maker's own charging guidance.
