If you want true wireless earbuds with a genuine fast-charge feature built in, choose HARMONY TWENTY-TWO HTT-17; if you need to fast charge a phone, tablet or laptop while still using a USB-C headphone, choose Viliqiou Dual USB C.
• HARMONY TWENTY-TWO HTT-17 biggest strength: True wireless earbuds with a 13mm dynamic driver, ENC call noise cancelling, Bluetooth 5.4, and a 10-minute charge that returns 100 minutes of playback.
• HARMONY TWENTY-TWO HTT-17 biggest trade-off: The charging case is plastic, the listed battery charge time is 45 minutes, and the ENC feature helps your voice on calls but does not cancel noise you hear.
• Viliqiou Dual USB C biggest strength: A 2-in-1 splitter that delivers up to 100W (20V/5A) fast charging while you use a USB-C headphone, plus 10Gbps data transfer over USB 3.2.
• Viliqiou Dual USB C biggest trade-off: It is an adapter, not a headphone — no audio hardware at all, no video output, and it only matters if your device has a single USB-C port.
• Pick HARMONY TWENTY-TWO HTT-17 if you want wireless earbuds that recharge fast between uses.
• Pick Viliqiou Dual USB C if you already own wired USB-C headphones and want to charge your phone or laptop at the same time.
The HTT-17 is aimed squarely at people who want wireless earbuds without babysitting the battery. The headline number is the fast-charge claim: 10 minutes in the case returns about 100 minutes of listening. That matters if you grab your earbuds on the way out the door and realize they're empty. The case itself holds a 500mAh battery and, per the specs, takes around 1.5 hours to charge, while the earbuds list a 45-minute charge time for their own 6 hours of playback. Total listening with the case is listed at 40 hours.
Where the HTT-17 makes sense: commuters, gym-goers (IPX5 covers sweat and light rain), and anyone who takes a lot of calls. The ENC four-mic setup is designed to pull your voice out of background noise for the person on the other end. In my opinion, that's the feature to care about if you take calls from a busy street or a café. The trade-off is honest: ENC is not ANC. It does not reduce what you hear while listening — it just makes you clearer on calls. If you want silence on a plane, this isn't that product. Skip it if you need active noise cancellation for yourself, or if you prefer over-ear fit.
Viliqiou Dual USB C: Who It's For
The Viliqiou adapter solves a very specific, very annoying problem: your phone, tablet or laptop has one USB-C port, and you can't charge it and plug in a USB-C headphone at the same time. This 2-in-1 splitter gives you two ports from one, so you can listen and charge simultaneously. The spec sheet lists 100W PD fast charging at 20V/5A, which is enough to keep most laptops and phones topped up at close to their original charging speed. It also builds in over-current, over-voltage, overheating and short-circuit protection, which is the part I'd actually want to see in a pass-through adapter.
The second port isn't just for audio. It complies with USB 3.2 and transfers data at up to 10Gbps, so you can move large video or high-res image files quickly between a drive and your device. One caveat the listing is upfront about: there's no video output. This is data and audio only, so don't buy it expecting to drive a monitor.
Physically it's tiny — 6 grams, white ABS and copper construction, and it ships with a small lanyard so you don't lose something that small in a bag. Compatibility is broad: laptops, tablets, smartphones, speakers, and USB-C headphones. Who should buy it? Anyone who has wired USB-C headphones and hates choosing between listening and charging, plus travelers and gamers who want both ports live. Who should skip it? Anyone whose device already has a separate headphone jack, and anyone hoping for HDMI or DisplayPort passthrough — that's not what this does.

If you want headphones — actual earbuds you listen through — the HTT-17 is the only one of these two that does the job, and its 10-minute fast charge is the standout feature for anyone who's constantly low on battery. I'd pick it for commuting, workouts and calls. The Viliqiou adapter is a smart, well-specified accessory, but it's not a headphone; buy it only if you already own USB-C headphones and need to charge at the same time. Different problems, different answers — match the product to the problem and you won't regret either.
FAQ
how to charge headphones faster
how to charge headphones
Place the HTT-17 earbuds back in the charging case, then connect the case with the bundled USB-C cable. The case itself holds a 500mAh battery and is listed at about 1.5 hours to charge, and it delivers up to 40 hours of total playback before it needs a top-up.
is fast charging bad for headphones
Not inherently. The HTT-17's fast-charge feature is a designed function of the earbuds and case, not a workaround, so using it as intended is fine. The Viliqiou adapter also builds in over-current, over-voltage, overheating and short-circuit protection for the devices it charges.
how to fast charge bose headphones
That's outside these two products — the HTT-17 is a HARMONY TWENTY-TWO model, not a Bose one. If you own USB-C headphones generally, the Viliqiou adapter can pass up to 100W of charging power to your device while the headphones stay plugged in.
