USB-C to 3.5mm Headphone Adapter Review: Keep Your Wired Earphones
Part of The Remote Work Travel Guide: Set Up an Office Anywhere
What we liked
- Works with most USB-C phones and tablets
- Supports headset mics
- Two in a pack
What we didn't
- Easy to lose
- Blocks charging while in use
- Quality varies by brand
Quick take
A pair of short dongles with USB-C on one end and a 3.5mm headphone socket on the other. Plug in wired earphones, a headset or an aux cable to any phone or tablet that dropped the jack.
Where to buy: USB-C to 3.5mm Headphone Adapter (2 Pack) on Amazon (typically about $5 to $10 for two).
What it is
Each adapter has a tiny DAC inside, because USB-C carries digital audio. They support headset microphones and inline controls on most devices.
Where it fits on the road
Wired earphones are the traveler’s backup: they never need charging and work on every plane seatback. The catch is the jackless phone. With a dongle permanently on your earphone cable, wired audio works on your phone, a borrowed laptop and many seatback screens.
“Wired never runs out of battery. That’s the whole reason I keep a pair.”

How it compares
- Apple USB-C to 3.5mm adapter. Well-reviewed DAC; pricier and sold singly.
- Phone-brand adapters. Most reliable on their own phones.
- Bluetooth earbuds. No dongle, but battery and pairing to manage.
Building a backup audio kit
A dongle, a pair of KZ ZS10 Pro earphones and a 1/8 to 1/4 adapter cover phones, laptops and DJ gear. For speakers, a USB-C to 1/4-inch DAC cable plays straight into amps.
Price and value
Expect to pay about $5 to $10 for two, though prices on Amazon move often, so check the current listing before buying. Excellent value for what it does: small, cheap and the reason your favorite wired earphones still work.
How I scored it
The 4.5-out-of-5 score combines my own use with what buyers report across retailers, weighed on value, build quality and how well it fits a travel and remote-work life. Read the full method on the editorial policy page.
3 tips to get the most out of it
- Leave one attached to your earphones. That’s the one you’ll actually have with you.
- If audio cuts out, flip or reseat it. Most issues are a half-connected plug.
- Use a dual-port adapter if you need to charge while listening. A single dongle blocks the port.
FAQ
Does it work on airplanes?
On USB-C seatback ports with audio, yes; many seatbacks still use 3.5mm directly.
Will the mic work on calls?
On most phones, yes.
Does it work with iPhone?
USB-C iPhones generally yes.
Who it’s for (and who should skip it)
Good for anyone keeping wired earphones with a jackless phone. Skip it if you’ve gone fully wireless. For the bigger picture, the Remote Work Travel Guide puts this alongside the full portable office setup.
Bottom line
Small, cheap and the reason your favorite wired earphones still work.
