• EarFun K1 — biggest strength: over-ear 40mm dynamic drivers, a 20Hz–20,000Hz range and a 3.5mm sharing jack so two kids can listen to one device without a splitter.
• EarFun K1 — biggest trade-off: it is a 180 g over-ear headset with no noise cancellation, so it is bulkier and lets outside sound in.
• MAS CARNEY USB C Headphones — biggest strength: in-ear earbuds with passive noise isolation, silicone tips in S/M/L and a 47 in (120 cm) cable with mic and remote.
• MAS CARNEY USB C Headphones — biggest trade-off: no volume limit and no sharing jack, so it is not aimed at young children.
• Choose EarFun K1 if you are buying for a kid, a classroom, a tablet or a Switch, and you want something that survives being folded, stretched and carried.
• Choose MAS CARNEY USB C Headphones if you want a light USB-C earbud for calls, music and video on a Samsung Galaxy or a newer iPhone with a USB-C port.
The EarFun K1 is a kids' headphone first and an audio product second, and the spec sheet shows it. It is an over-ear design in USB-C Violet, with leather and plastic enclosures, a 32 ohm impedance, 100 dB sensitivity and a frequency response that runs the full 20Hz to 20,000Hz. The driver is a 40mm dynamic unit, which is a large diaphragm for a headphone in this class — that size is usually what gives over-ear cans their fuller, more spread-out stereo image compared with tiny earbuds.
Then there are the two features that actually decide the purchase. First, the volume limit, listed as 85/94dB. That is the whole reason a parent picks this model over a generic wired headphone: there is a ceiling on how loud it can get. Second, the 3.5mm sharing jack. A second pair of headphones plugs straight into the K1, so two kids can watch the same tablet or play the same game with no splitter and no extra cable to lose. The inline mic and button remote handle play/pause, track skipping and calls, which covers online lessons and video chat.
In my opinion, this is the right pick if the listener is a child, if the device is a Kindle Fire Tablet, Switch, Chromebook or PC with a USB-C port, and if the headphone is going to live in a backpack. The adjustable headband stretches for different head sizes, and the foldable build makes it easy to store. EarFun also covers it with an 18-month warranty.
MAS CARNEY USB C Headphones: Who It's For
The MAS CARNEY USB C Headphones are the opposite philosophy. These are in-ear earbuds, model TI6, in black, with a USB-C jack and a wired connection. Instead of a volume cap and a sharing port, the feature list is about everyday phone use: an in-line mic, in-line volume control, and push-button plus touch control on the cable, so you can answer a call, change volume or pause without pulling the phone out.
The cable is 47 inches, roughly 120 cm — long enough to go from a pocket to your ears with slack, short enough that it is not a trip hazard on a desk. The set ships with noise isolation ear tips in S/M/L, which matters more than people expect: the tip has to seal your ear canal for the passive noise reduction to do anything. The product listing describes passive noise cancellation, meaning it blocks sound by physically sealing the ear rather than by active electronics. No battery, no charging, no pairing.
This is the earbud for someone whose phone no longer has a headphone jack. The title names Samsung Galaxy S25 FE, S26, S25, S24, A16, A17 and iPhone 17 Pro Max, 17e, 16, 16e and 15 Plus — all USB-C devices. If that is your phone, you plug in and you are done.
Who should skip it? Anyone buying for a young child. There is no volume limit listed here, and the small in-ear tips are a choking-shaped design decision for toddlers. It is also a single-item pack, so there is no spare pair in the box.
• Best for young kids and school → EarFun K1. The 85/94dB volume limit is the deciding feature, and the over-ear fit does not go inside a child's ear canal.
• Best for sharing → EarFun K1. The 3.5mm sharing jack lets a second headphone plug in with no splitter.
• Best for a phone with no headphone jack → MAS CARNEY USB C Headphones. USB-C plug, in-line mic and in-line volume control in one cable.
• Best for blocking out the world → MAS CARNEY USB C Headphones. Passive noise isolation with S/M/L ear tips beats an over-ear with no noise control.
• Best for comfort over long sessions → EarFun K1. A 180 g over-ear with an adjustable, stretchable headband spreads pressure over the head instead of inside the ear.
• Best for portability → MAS CARNEY USB C Headphones. Earbuds and a 47 in cable fold into a pocket; the K1 folds too, but it is still a full-size headphone.
• Best for big, roomy sound → EarFun K1. A 40mm dynamic driver with a 20Hz–20,000Hz range is simply more diaphragm than an in-ear can offer.
• Best for calls and lessons → either, for different reasons. The K1's inline mic suits a kid on a Chromebook; the MAS CARNEY remote suits an adult taking calls on a Galaxy.
If I were buying for myself, I would take the MAS CARNEY USB C Headphones. In my opinion, if your phone is USB-C, the combination of in-line mic, in-line volume control, a 47 in cable and passive noise isolation makes it the more practical everyday object — it does the phone job without adapters or charging.
But I would not hand them to a seven-year-old. For a child, I would buy the EarFun K1 every time, because the 85/94dB limit and the sharing jack are features the MAS CARNEY simply does not have, and those two things matter more than sound quality in that use case. Decide who is wearing them, then the answer is obvious. Check the current price on Amazon for whichever one fits.
how to connect usb c wired headphones
Plug the USB-C connector straight into your device's USB-C port. There is no pairing, no battery and no app involved with either of these — the connection is purely wired. If your device only has a Lightning or 3.5mm port, you would need an adapter, since both models here terminate in USB-C.
how to connect usb wired headphones to macbook
A modern MacBook with USB-C ports accepts these directly: push the connector into any USB-C port and the Mac switches audio output to the headphones. The MAS CARNEY set and the EarFun K1 both use a wired USB-C connection, so no driver install is described for either. If your Mac has a 3.5mm jack instead, you would need a USB-C-to-3.5mm adapter.
how to use usb c wired headphones on mac
Once plugged into a USB-C port, use the system sound settings to confirm the headphones are the selected output, then adjust volume from there or from the in-line remote. The MAS CARNEY earbuds add in-line mic and volume control plus push-button and touch controls on the cable. The EarFun K1 uses button controls on its remote for play/pause, calls and track skipping.
how to connect usb wired headphones to xbox
The EarFun K1 lists Switch, Chromebook, PC and Kindle Fire Tablet among compatible devices, so a USB-C connection to a console-style device is the intended pattern. Whether a given Xbox controller or console accepts USB-C audio depends on that hardware's own ports and settings, so check the console's audio output options first. Neither product lists Xbox in its compatibility description.
