If you want a two-pack of dual USB-C headphone adapters with a Hi-Res DAC and a slim plug-and-play dongle for charging and listening at the same time, choose Kefiany Dual USB-C Headphone; if you need a single 2-in-1 adapter tuned specifically for Google Pixel and the newest iPhone and Samsung lineups, choose VIFIGEN USB C.
• Kefiany Dual USB-C Headphone — biggest strength: You get two adapters in one package, each combining a 60W PD charging pass-through with a 3.5mm audio jack and an upgraded 24bit/96kHz DAC.
• Kefiany Dual USB-C Headphone — biggest trade-off: It only works with digital USB-C earphones (not analog ones), it doesn't support OnePlus or Moto phones, and on iOS you can't answer or end calls from the headphone remote.
• VIFIGEN USB C — biggest strength: Very wide device compatibility list that reads like a who's-who of current Pixel, iPhone, Samsung, iPad and LG models, with a 24bit/96kHz DAC and built-in noise cancellation.
• VIFIGEN USB C — biggest trade-off: It ships as a single adapter, it does not support data transfer, and quick charge may not work on some newer phone models.
• Pick Kefiany Dual USB-C Headphone if you want a spare adapter for a second bag or desk and you listen on a Samsung, iPad or iPhone 15-class USB-C device.
• Pick VIFIGEN USB C if you're on a Google Pixel or a recent Samsung/iPhone model and you just need one reliable charging-plus-audio dongle.
The Kefiany adapter is a 2-in-1 dongle that splits one USB-C port into a 3.5mm audio jack and a charging pass-through. Its headline number is 60W PD charging, which the built-in Power Delivery chip delivers at up to 20V/3A. In plain terms, that's enough headroom to keep a phone or tablet topped up while you're listening, rather than watching the battery drain while you stream. The upgraded DAC handles up to 24bit/96kHz, so it's aimed at people who care about clean, stable audio rather than a bare-bones pass-through.
What you actually get is the 2-pack, which is the detail that shapes who this is for. One adapter can live in your laptop bag and the other can stay plugged into a desk charger, so you're not constantly unplugging and re-plugging a single dongle. It's plug-and-play with no drivers, and the slim body is designed to disappear into a pocket or the corner of a bag. The compatibility list covers USB-C phones, tablets and laptops — iPhone 15 series, iPad 10, Air 4/5, mini 6, the 2018–2023 iPad Pro models, Samsung Galaxy S22/S21/S20 families, Note 20 Ultra/10+, Fold and Flip models, LG G5/G6/Stylo, Pixel 5/4XL/3XL/2XL, and MacBook Pro.
Two practical notes matter before you buy. First, this adapter only works with digital USB-C earphones — analog USB-C earphones won't work, so check your headphones if you're not using a standard 3.5mm pair. Second, it does not work with OnePlus or Moto phones, and on iOS devices the call answer/end button only works on the phone itself, not on your headphone remote. If you're on a Samsung, iPad or iPhone 15-class device and want a spare adapter, this is a sensible pick. If you're on OnePlus, Moto, or you rely on analog USB-C earbuds, skip it.
The VIFIGEN adapter does the same core job — one USB-C port becomes a 3.5mm headphone jack plus a 60W PD charging pass-through — but it leans hard into compatibility and audio polish. The integrated chip manages voltage and current stability to help protect the connected device, and the DAC supports 24bit/96kHz with built-in noise cancellation, which is the kind of spec that matters if you take a lot of calls and want to avoid hiss or buzz in the background.
The compatibility list is the real story here. It covers the Google Pixel line in unusual depth (Pixel 10a, 10, 10 Pro, 10 Pro XL, 10 Pro Fold, 9a, 9 Pro Fold, 9 Pro, 9, 8a, 8 Pro, 8, 7a, 7 Pro, 7, 6, 5, 4 XL, 4, 3 XL, 3), the current iPhone 15/16/17 families, a long sweep of Samsung Galaxy S and A series plus Z Fold and Z Flip, iPad Pro/Air/Mini, and LG G/V-series and Stylo models. If you're a Pixel owner, that specificity is a genuine advantage over the Kefiany list, which stops at Pixel 5.
The trade-offs are clear. It ships as one adapter, not two, so there's no built-in spare. Data transfer is not supported — this is charging and audio only. And VIFIGEN itself warns that quick charge may not work with certain newer phone models and recommends a PD wall charger for the best speed. In-line remote functions do work, and there's no driver install. Buy it if you're on a Pixel or a recent Samsung/iPhone and want one well-rounded dongle. Skip it if you need a backup unit or you were hoping to move files through it.
• Best for getting two adapters → Kefiany Dual USB-C Headphone (2-pack versus VIFIGEN's single unit).
• Best for Google Pixel owners → VIFIGEN USB C (explicit Pixel 10/9/8/7/6/5/4/3 coverage versus Kefiany's Pixel 5 ceiling).
• Best for Samsung and iPad households → either works, but Kefiany's 2-pack spreads across more devices at once.
• Best for call clarity → VIFIGEN USB C (built-in noise cancellation on top of the 24bit/96kHz DAC).
• Best if you use in-line headphone controls → VIFIGEN USB C, since Kefiany limits call answer/end to the phone itself on iOS.
• Best if you have analog USB-C earbuds → neither reliably; Kefiany explicitly excludes analog USB-C earphones, so check your gear first.
• Best if you're on OnePlus or Moto → neither — Kefiany states it doesn't work with those brands.
• Best for a spare-for-the-bag setup → Kefiany Dual USB-C Headphone, purely because you get two.
In my opinion, most people shopping for a fast-charge headphone adapter are on a Samsung, iPad or iPhone 15-class device, and the Kefiany Dual USB-C Headphone wins that group on the strength of the 2-pack alone — a spare adapter you don't have to think about is worth more day to day than a slightly longer compatibility list. But if you own a Google Pixel, I'd take the VIFIGEN USB C without hesitation, because that Pixel coverage is the whole point of the purchase. Both give you 60W PD charging and a 24bit/96kHz DAC, so the decision really comes down to how many adapters you want and which phone is in your pocket. Check the current price on Amazon before you commit, since that gap can shift the math.
FAQ
How to charge headphones faster
These adapters don't charge your headphones — they pass charging power through to your phone or tablet while you listen. Both are rated for up to 60W PD, and both brands recommend pairing them with a PD wall charger rather than a standard USB port to get the fastest result.
How to charge headphones
Is fast charging bad for headphones
Not in this setup. The charging current goes to your phone or tablet, not to your headphones — the audio signal is handled separately by the DAC. VIFIGEN adds an integrated chip to manage voltage and current stability, which the brand describes as helping protect the connected device.
How to fast charge Bose headphones
These two adapters won't do that. They're designed to charge the USB-C phone or tablet they're plugged into while passing audio to a 3.5mm jack, so a Bose headphone's own charging has to come from its own cable and charger. Use a PD wall charger for the fastest result on the host device.
