If you want a fast-charge power setup that actually tops up your headphones and earbuds, choose ienza USB-C Headphone Earbud; if you need to keep a wired headset plugged in while your phone fast-charges during the workday, choose Liaoan USB C Headphone. One is a charger. One is an adapter. That single difference decides everything below, especially if you're equipping a desk for work.
• ienza USB-C Headphone Earbud — biggest strength: it's a complete fast-charging kit, a QC3.0 wall adapter plus a USB-A to USB-C cable, rated at 20W output, 5V, 4A, so it's built to push power into USB-C headphones and earbuds quickly.
• ienza USB-C Headphone Earbud — biggest trade-off: it charges gear, it doesn't adapt audio. If your phone has no headphone jack and you want to plug in a wired headset, this doesn't solve that problem.
• Liaoan USB C Headphone — biggest strength: a 2-in-1 USB-C adapter with an IP headphone jack that lets you listen and charge at the same time, with up to 100W fast charging and a DAC chip for HiFi audio decoding.
• Liaoan USB C Headphone — biggest trade-off: it does NOT support data transfer, and it's a dongle, not a charger, so it needs your existing power source to do anything.
• Who each pick is for: ienza for anyone whose USB-C headphones, earbuds or speakers need reliable fast charging at home or at a desk; Liaoan for anyone who wants a wired headset for work while their phone keeps charging.
The ienza set is refreshingly uncomplicated: one compact rectangular AC wall adapter and one USB-A to USB-C cable. The adapter is a QC3.0 fast charger rated at 20 watts, 5 volts and 4 amps output, with a 2.22A current rating and a standard North American 2-pin Type A plug. The enclosure is copper with a black finish, and it's a corded-electric device, so there's no battery to think about. You plug it in, you charge.
What it does best is fast charge headphones and earbuds specifically. The compatibility list reads like a who's-who of USB-C audio gear: Beats Flex and Studio Buds, Sony earbuds and headphones with a USB-C port, Bose Sport Earbuds, Samsung Galaxy Buds Live, Jabra Elite 75t, Sennheiser, Beyerdynamic, plus portables like the JBL Go 3, Charge 4, Flip 5 and Pulse 4. If your daily carry is a pair of USB-C earbuds, this is the charger you leave in your bag or on your desk so you're never hunting for the cable that actually fits.
Who should buy it? Anyone whose priority is getting USB-C headphones or earbuds back to full as quickly as the device allows, and who wants the adapter and cable handled in one purchase instead of two. It also suits a shared charging spot, since one output port and one cable keeps things simple. Who should skip it? If your real problem is a phone with no headphone jack, or you need to listen and charge simultaneously, this isn't the tool — that's the Liaoan's job. Also skip it if you need multiple ports at once, because there's only one.
The Liaoan adapter solves a very specific annoyance: your device has USB-C, your wired headset has an IP-style jack, and you want both connected at once. The 2-in-1 design gives you a USB-C pass-through for charging and a headphone jack for audio, so you can listen to music, take calls, watch video or game while the battery keeps climbing. It's a small orange dongle with two ports and no plug of its own — it borrows power from whatever USB-C source you already own.
Two specs stand out. First, fast charging up to 100W, which is a serious ceiling for a little adapter and means it won't be the bottleneck in a fast-charging chain. Second, the HiFi claim is backed by a highly integrated DAC decoding chip, which the sheet describes as delivering stable, noise-free conversion and clearer voice calls. For a headset for work, that matters — call clarity is the whole point.
Compatibility covers Phone 17/17 Plus/17 Pro/17 Pro Max, Phone 16 and 15 families, Pad Air and Pad Pro, plus Galaxy S21, S20, S10, Note20, Note10, G7 and V20, and other USB-C devices. Who should buy it? Anyone who wants a wired headset for work without giving up charging — the classic "one port, two needs" scenario. Who should skip it? If you need to move files or sync data through the adapter, look elsewhere, because it explicitly does not support data transfer. And if you want a charging brick rather than an adapter, this isn't it.
• Best for fast charging headphones and earbuds → ienza USB-C Headphone Earbud. 20W QC3.0 output with a matching cable, ready to use out of the box.
• Best for listen-while-charging → Liaoan USB C Headphone. The 2-in-1 jack plus USB-C pass-through is the entire reason it exists.
• Best for the highest fast-charge ceiling → Liaoan USB C Headphone. Up to 100W, versus 20W on the ienza adapter.
• Best for call and audio quality → Liaoan USB C Headphone. The integrated DAC chip targets HiFi decoding and clearer voice calls.
• Best for a complete, no-extras charging kit → ienza USB-C Headphone Earbud. Adapter and cable together, nothing else required.
• Best for a wired headset for work → Liaoan USB C Headphone. Plug in your headset, keep the phone charging, take the call.
• Best for charging speakers and a wide range of USB-C audio brands → ienza USB-C Headphone Earbud. The compatibility list spans Sony, Bose, Beats, JBL, Samsung, Jabra and more.
• Skip the adapter if you need data transfer → Liaoan USB C Headphone, since it doesn't support it.
For work, I would buy the Liaoan USB C Headphone. Here's my reasoning: a desk setup usually means one thing — you want your wired headset on and your device charging at the same time, and the Liaoan is the only one of the two that does both, with a 100W ceiling and a DAC chip aimed at clean call audio. I'd pick the ienza instead if your actual need is fast-charging USB-C headphones or earbuds, because a 20W QC3.0 adapter plus cable is the more useful purchase there. Two different jobs, two different answers. Check the current price on Amazon before you commit.
how to charge headphones faster
Use a fast-charging adapter matched to your headphone's USB-C port. The ienza set pairs a QC3.0 20W wall adapter with a USB-A to USB-C cable, giving USB-C headphones and earbuds a higher-output charge than a standard low-wattage brick.
how to charge headphones
Connect the headphone's USB-C port to a power source with the right cable and adapter. The ienza kit includes both an AC wall fast charger and a USB-A to USB-C cord, and it's compatible with USB-C headphones from Sony, Bose, Beats, JBL, Samsung, Jabra and similar brands.
is fast charging bad for headphones
There's nothing in these data sheets suggesting fast charging harms headphones. The ienza adapter outputs 20W at 5V and 4A, and the Liaoan adapter supports up to 100W pass-through, both framed as standard fast-charging features rather than risks. Follow your headphone maker's guidance.
how to fast charge bose headphones
Bose Sport Earbuds appear on the ienza compatibility list, so pairing them with the ienza QC3.0 20W adapter and its USB-A to USB-C cable is the straightforward route. For a wired Bose headset used while charging, the Liaoan adapter's 2-in-1 jack and USB-C pass-through is the alternative.
