If you want the fastest possible charge for your USB-C headphones and phone at the same time, choose JBJBBG USB C Splitter，2; if you need a more rugged adapter with a tangle-free cord and a longer warranty, choose BENFEI USB C Splitter.
• JBJBBG USB C Splitter，2 — biggest strength: PD 100W pass-through charging plus a Realtek DAC for Hi-Res audio, so your phone charges fast while your USB-C headphones keep playing clean sound.
• JBJBBG USB C Splitter，2 — biggest trade-off: No stated durability rating or bend-test figure, and the cable is a fixed dongle design rather than a hideaway one.
• BENFEI USB C Splitter — biggest strength: 60W charging with a 32bit/96kHz DAC, a strain-relief design rated for 30,000+ bends, and a hidden-cord layout that resists tangling.
• BENFEI USB C Splitter — biggest trade-off: Its 60W ceiling is lower than JBJBBG's 100W, so it won't push the fastest charge into a large laptop or a power-hungry phone.
• Who each pick is for: Go JBJBBG for maximum charging speed and Hi-Res headphone listening; go BENFEI for daily pocket carry and long-term durability.
The JBJBBG USB C Splitter，2 is built around one idea: don't make me choose between charging and listening. It's a 2-in-1 USB-C adapter that gives you a USB-C headphone jack and a PD 100W USB-C charging port in the same dongle. That 100W figure is the headline. It means the adapter is designed to pass through serious power, so a phone that supports fast charging can top up quickly while you keep your USB-C earphones plugged in.
The audio side is handled by a Realtek DAC with Hi-Res decoding. In plain terms, that's the chip responsible for turning the digital signal into clean analog sound, and JBJBBG specifically calls out lossless transmission and no current noise. If you own USB-C headphones and you've ever heard a faint hiss or buzz from a cheap adapter, that's the problem this chip is meant to solve. It also supports phone calls and volume control, so you're not losing headset functionality.
BENFEI USB C Splitter: Who It's For
BENFEI's USB C Splitter takes the opposite emphasis: it's the everyday-carry adapter. It's a 1-in-2-out dual USB-C audio jack adapter with 60W fast charging, and BENFEI leads with the "no battery worries" angle — listen to music and take calls while the phone stays topped up. Line control and microphone pass-through are supported, so your inline remote still works.
Where BENFEI clearly invests is build and audio spec. The DAC chip is rated up to 32bit/96kHz with noise reduction, and it auto-adapts to both analog and digital USB-C headphones — a genuinely useful detail, because not every USB-C headset is wired the same way. It also supports USB 2.0 data transfer, which the JBJBBG sheet doesn't mention. On durability, BENFEI states a strain-relief design rated for 30,000+ bending tests, shielded enamel wire for stable signal, and metal-coated connectors for better contact. And the cord is a hidden-cord design, so it tucks away instead of tangling in your bag. BENFEI backs it with an 18-month warranty.
Who should buy it? People who treat an adapter as a long-term pocket item — commuters, students, anyone who pulls it out and stuffs it back dozens of times a day. The bend rating and hideaway cord are aimed squarely at that. Who should skip it? If you need the highest charging wattage available for a laptop or a fast-charging phone, 60W is the ceiling here, and that's the one place JBJBBG pulls ahead.
Side-by-Side: Which Should You Choose?
• Best for the fastest possible charge → JBJBBG USB C Splitter，2. PD 100W versus BENFEI's 60W is the clearest spec gap between them.
• Best for Hi-Res headphone listening → JBJBBG USB C Splitter，2. Its Realtek DAC is described as Hi-Res with lossless transmission.
• Best for mixed headphone types → BENFEI USB C Splitter. It auto-adapts to both analog and digital USB-C headphones.
• Best for tangle-free storage → BENFEI USB C Splitter. The hidden-cord design is the specific fix for bag tangling.
• Best for charging a laptop through the adapter → JBJBBG USB C Splitter，2. Higher wattage headroom suits larger devices; both sheets list MacBook-class compatibility.
• Best if you want data transfer too → BENFEI USB C Splitter. USB 2.0 data transfer is listed; JBJBBG's sheet does not mention data.
• Best warranty clarity → BENFEI USB C Splitter. An 18-month warranty is stated outright.
If I were buying for myself and my main goal were fast-charging my phone while my USB-C headphones stay plugged in, I'd pick the JBJBBG USB C Splitter，2. The 100W PD path is the stronger charging spec on paper, and the Realtek Hi-Res DAC is the better-matched audio chain for USB-C earphones. I'd only switch to the BENFEI USB C Splitter if durability and tidy storage mattered more to me than peak wattage — in my opinion, its bend rating, hidden cord and 18-month warranty make it the safer long-term companion for someone who carries an adapter everywhere. Either way, check the current price on Amazon before you commit, since that's the one thing specs can't tell you.
how to charge headphones faster
Use a charging source that matches what your headphones accept, and remove anything in the chain that throttles it. With these adapters, the JBJBBG USB C Splitter，2 passes through up to PD 100W while the BENFEI USB C Splitter tops out at 60W, so the higher-wattage path is the one to choose if your device can take advantage of it.
how to fast charge bose headphones
Bose headphones charge over their own connector, not through a USB-C splitter's audio path, so the splitter's job is to keep your phone topped up while you listen. Pick the adapter whose charging spec matches your phone's fast-charge capability — 100W on the JBJBBG, 60W on the BENFEI — and use a charger and cable rated for that wattage.
how to charge headphones
Plug your headphones into their normal charging cable and a compatible power source. If you're using one of these adapters, the headphone side carries audio while the second port carries power, so you can charge your phone and listen at the same time rather than swapping cables.
is fast charging bad for headphones
The charging spec here describes power delivered to your phone through the adapter, not to the headphones. JBJBBG states its tin-plated copper core is designed for safe, stable fast charging that doesn't hurt the phone; BENFEI frames its 60W path as a way to avoid battery worries. Follow your headphone maker's own charging guidance for the headphones themselves.
