• Togconn Dual USB C — biggest strength: a true USB-C-to-USB-C splitter. It gives you two USB-C paths, so you can plug in USB-C audio gear and still charge at up to 60W (20V 3A) through a built-in smart chipset.
• Togconn Dual USB C — biggest trade-off: because both outputs are USB-C, it's the wrong tool if your headphones end in a traditional round plug. It also splits one port into three, so it's a small dongle you have to keep track of.
• Liaoan USB C Headphone — biggest strength: it converts your USB-C port into a headphone jack while charging, and it pushes fast charging up to 100W with a dedicated DAC chip for HiFi decoding.
• Liaoan USB C Headphone — biggest trade-off: no data transfer, and the audio side is built around a headphone jack rather than USB-C audio, so it won't help USB-C headphone owners.
• Who each pick is for: Togconn for USB-C earbud and USB-C headset users who charge and listen at once; Liaoan for anyone with wired jack headphones who wants the fastest charging headroom.
The Togconn adapter is a 2-in-1 USB-C male-to-double-Type-C splitter. In plain terms: one end goes into your phone or tablet, and the other side gives you a USB-C audio connection plus a USB-C charging connection. That's the whole point. You plug in a USB-C headset, plug in your charging cable, and do both at the same time. No driver, no setup — it's plug and play with a built-in smart chipset that handles the power negotiation for you.
The charging spec is the headline number here: up to 60W, delivered as 20V at 3A. For most phones and tablets that's plenty to keep the battery climbing while you stream music, take calls or sit in a long video meeting. It won't match the fastest laptop-class charging, but that's not what this dongle is for. It's for the everyday situation where your phone is at 15 percent and you still want to finish the album.
Compatibility is broad across USB-C devices: iPhone 16 series, Galaxy S20 through S22 Ultra, Z Fold 3 and 4, Note 20, iPad Pro, and Pixel 3 and 4 among others. Buy it if you own USB-C headphones or a USB-C headset and you're tired of choosing between charging and listening. Skip it if your headphones use a traditional headphone jack — this adapter simply doesn't have that port.
Liaoan USB C Headphone: Who It's For
Liaoan's adapter approaches the same problem from the opposite direction. It's a 2-in-1 USB-C adapter that adds a headphone jack while charging your USB-C device. So instead of two USB-C ports, you get one USB-C charging path and one audio jack for wired headphones. If you've got a favorite pair of wired headphones with a round plug and a phone that dropped the jack, this is the bridge.
The charging ceiling is the highest in this comparison: up to 100W. That's a meaningful number for anyone carrying a laptop or tablet that can actually pull that kind of power, and it means the adapter won't be the bottleneck in a fast-charging setup. Note the design detail: the power plug type is listed as "No Plug," meaning the adapter itself doesn't include a charger — you supply the cable and brick.
Audio is handled by a highly integrated DAC decoding chip, which Liaoan says delivers HiFi audio decoding with stable, noise-free conversion and clearer voice calls. A dedicated DAC is the right way to do this — it converts the digital signal properly instead of relying on a passive passthrough, which is exactly why jack adapters with real DACs tend to sound cleaner on calls.
Side-by-Side: Which Should You Choose?
• Best for USB-C headphone owners → Togconn Dual USB C. It's the only one of the two with a USB-C audio output, so USB-C earbuds and headsets actually work with it.
• Best for traditional wired headphones → Liaoan USB C Headphone. The headphone jack output is the entire reason to pick this one.
• Best charging headroom → Liaoan USB C Headphone. Up to 100W versus Togconn's up to 60W (20V 3A).
• Best for laptop or tablet charging → Liaoan USB C Headphone. Higher wattage ceiling suits bigger devices that can draw more power.
• Best for phone-and-earbuds multitasking → Togconn Dual USB C. Charging plus USB-C audio on one dongle is exactly the commute-and-call scenario.
• Best for clearer voice calls on a wired headset → Liaoan USB C Headphone. The dedicated DAC chip with HiFi decoding and noise-free conversion is built for that.
• Best for durability reassurance → Togconn Dual USB C. Aluminum shell, heat dissipation, and a 10,000+ plug-cycle rating, plus a 24-month warranty.
• Best for travel simplicity → Togconn Dual USB C. At about 0.01 kg with a compact aluminum body, it's the lighter thing to carry.
In my opinion, the right buy depends entirely on which headphone plug you own, and that's not a dodge — it's the one spec that decides this. If your headphones end in USB-C, I'd take the Togconn Dual USB C, because it's the only adapter here that lets USB-C audio and charging coexist, and the aluminum build plus 10,000+ plug-cycle rating gives me confidence it'll survive daily use. If your headphones end in a traditional jack, I'd take the Liaoan USB C Headphone instead: 100W charging and a real DAC chip make it the stronger fit for wired-jack listeners who also want maximum charging headroom. Match the port to your headphones and you'll be happy either way.
how to charge headphones faster
Charging speed is set by the weakest link in the chain: your charger, your cable, and the adapter. With this pair, the Liaoan adapter supports up to 100W and the Togconn adapter supports up to 60W (20V 3A), so pairing either with a charger and cable that can deliver that much power is what lets the adapter run at its ceiling.
how to charge headphones
For USB-C headphones, plug them into the Togconn Dual USB C adapter's USB-C audio port and run your charging cable into the same dongle — the built-in smart chipset manages both at once. For wired jack headphones, use the Liaoan USB C Headphone adapter, which gives you a headphone jack plus a USB-C charging path in one unit.
is fast charging bad for headphones
Neither adapter's charging output runs through the headphones themselves — the power goes to your phone or device, while audio is handled separately. The Togconn adapter relies on a smart chipset to negotiate power, and the Liaoan adapter uses a DAC for audio decoding, so the fast-charging path and the audio path are distinct in both designs.
do these adapters work with iPhone 17 or iPhone 16
The Togconn adapter lists iPhone 16, 16 Plus, 16 Pro and 16 Pro Max among its compatible devices. The Liaoan adapter lists iPhone 17, 17 Plus, 17 Pro, 17 Pro Max as well as the iPhone 16 and 15 families. Check your specific model against the compatibility list before ordering, and check the current price on Amazon before you commit.
