If you want a USB-C audio adapter that lets you charge and listen at the same time, choose BENFEI USB C; if you need one dongle that covers both Lightning iPhones and USB-C devices, choose Weleecty USB C.
• BENFEI USB C — biggest strength: It combines a 3.5mm headphone jack with 60W pass-through charging, so you can listen on wired headphones and top up your battery through the same port.
• BENFEI USB C — biggest trade-off: It's USB-C only. If you still carry a Lightning iPhone, this adapter has nothing to plug into.
• Weleecty USB C — biggest strength: Two connectors in one body — Lightning and USB-C — so a single dongle works across an iPhone 17/16/15, a Galaxy S24, an iPad, or a Mac.
• Weleecty USB C — biggest trade-off: No charging pass-through. It's for listening, not for powering your phone back up while you listen.
• Pick BENFEI USB C if you're all-in on USB-C and want to keep charging while you use wired headphones.
• Pick Weleecty USB C if you juggle devices, or you're still on a Lightning iPhone and want one adapter that survives the switch to USB-C.
The BENFEI adapter is a USB-C male plug on one end and a 3.5mm female jack on the other, with a 60W charging cord built in. That last part is the whole point. On a modern phone with no headphone jack, plugging in a dongle usually means giving up your charging port for as long as you want to listen. BENFEI's design gives it back, rated at 60W and 3A, which comfortably covers phone and tablet charging over USB-C.
Inside, it uses a dedicated DAC chip rather than relying on your phone's onboard audio, and the pitch is high-definition audio with noise reduction. The connector is metal-coated for a tighter, more consistent contact, and the internal wiring is shielded enamel to keep the signal clean. Around the plug itself there's a strain-relief design rated for 30,000+ bend cycles, which is the part of a dongle that normally fails first when it lives in a bag or a pocket.
There's also a hidden-cord design — the charging cable tucks away instead of dangling — plus a glossy grey finish. BENFEI backs it with an 18-month warranty and a stated compatibility list that reads like a USB-C who's-who: iPhone 15 Pro Max, 15 Pro, and 15, the Galaxy S24/S23/S22/S21 Ultra line, iPad Pro, and Pixel 8.
So who is this for? Someone who already lives in USB-C land, listens on wired headphones or IEMs, and is tired of choosing between music and a charge. It's a strong fit for commuters, for anyone who takes calls on a wired headset and wants the wire control function the adapter supports, and for people who want one dongle that doubles as a charging extension.
Who should skip it? If you own a Lightning iPhone — anything from the 14 backward — this adapter simply isn't for you. And if you never charge while listening, you're paying for a feature you won't use. In my opinion, this is the pick for a USB-C-only household that wants the dongle to do two jobs well rather than one job across two standards.
Weleecty takes the opposite approach. Instead of one connector and one extra feature, it packs two connectors into one compact body: a Lightning to 3.5mm path for Apple devices and a USB-C to 3.5mm path for everything modern. That's the "two adapters in one" idea, and it's genuinely useful if your drawer currently holds a Lightning dongle, a USB-C dongle, and a permanent low-level anxiety about which one you grabbed.
The audio side is more explicitly specified than most dongles at this level. Weleecty lists a precision DAC chip with lossless output up to 24-bit/96kHz and advanced noise cancellation aimed at killing static and interference. That's a meaningful detail for anyone who cares about wired audio — 24-bit/96kHz covers high-resolution listening well beyond what a phone's stock output typically manages, and the noise-cancellation claim speaks directly to the most common complaint about cheap adapters, which is hiss or crackle when the cable moves.
The rest of the design is about portability. Weleecty describes it as ultra-compact — small enough for a pocket, wallet, or the smallest compartment of a bag — and built to survive commutes, gym sessions, and travel. The compatibility list is broad by design: iPhone 17/16/15/14/13/12 Pro, Galaxy S24/S23, iPad, and Mac. It carries a 2-year warranty, and the listing frames it as a bridge between old and new technology — which is exactly what it is.
Who is this for? Two groups. First, anyone in a mixed-standard household — a Lightning iPhone and a USB-C Android, or an iPhone that's about to be replaced by a USB-C model. Second, travelers who want one dongle in the bag instead of two. Podcast listeners, movie watchers, and music lovers who want a clean signal from wired headphones are the target audience the spec sheet describes.
Who should skip it? If charging while listening matters to you, Weleecty doesn't offer it — there's no pass-through power here. And if every device you own is USB-C, the Lightning half is dead weight, though harmless.
Side-by-Side: Which Should You Choose?
• Best for charging while you listen → BENFEI USB C. 60W, 3A pass-through is the feature Weleecty doesn't have.
• Best for mixed Lightning + USB-C households → Weleecty USB C. One accessory replaces two dongles.
• Best for USB-C-only setups → BENFEI USB C. Every part of the design is aimed at modern USB-C phones, tablets, and laptops.
• Best for durability under daily abuse → BENFEI USB C. The 30,000+ bend rating and strain relief are called out specifically, and that's the failure point on dongles.
• Best for tangle-free storage → BENFEI USB C. The hidden-cord design keeps the charging lead from snagging in a bag.
• Best for travel with one bag, many devices → Weleecty USB C. Ultra-compact, two connectors, nothing extra to pack.
• Best for long-term peace of mind → Weleecty USB C, on the strength of its 2-year warranty versus BENFEI's 18-month coverage.
• If you own an iPhone 14 or older → Weleecty USB C, because BENFEI's USB-C plug can't connect to Lightning at all.
I'd buy the BENFEI USB C. The charging pass-through is the feature that changes how the adapter fits into a day — you plug in headphones, you keep your battery topped up, and you stop treating your one USB-C port as a resource to ration. Add the strain-relief rating and the hidden cord, and it's the dongle I'd trust to survive a year in a jacket pocket.
That said, Weleecty wins on breadth, and it isn't close. If you're still on a Lightning iPhone, or you're the person everyone borrows a cable from, the dual-connector design is the smarter buy. Both are worth checking the current price on Amazon before you commit — the decision here is about which job you need done, and that answer is different for everyone.
FAQ
If you charge and listen at the same time, yes. The 60W pass-through charging is the reason to choose it over a basic USB-C to 3.5mm adapter, and the 30,000+ bend rating suggests it's built for daily carry rather than occasional use.
Yes. It has both a Lightning connector and a USB-C connector, so it covers Lightning iPhones plus USB-C phones, tablets, and laptops like the Galaxy S24/S23, iPad, and Mac. That dual-connector design is its main advantage.
No. Weleecty's adapter is for audio only — there's no charging pass-through listed. If charging while listening is a requirement, the BENFEI USB C is the one that supports it.
Weleecty publishes the more specific audio claim, listing lossless output up to 24-bit/96kHz with noise cancellation, while BENFEI emphasizes a DAC smart chip with high-definition audio and noise reduction. Both use a dedicated DAC; Weleecty's numbers are simply the more detailed of the two on paper.
Yes — prices move, and this comparison deliberately doesn't quote them. Use the current price on Amazon for each adapter and weigh it against which features you actually need.
