• JVC ORANGE GUMY — biggest strength: A complete, ready-to-use pair of wired earbuds with three sizes of ear tips and a standard 3.5 mm jack, so there's nothing else to buy.
• JVC ORANGE GUMY — biggest trade-off: It only works with devices that still have a 3.5 mm headphone jack, and it's a single-listener product.
• ZOOAUX PRO USB C — biggest strength: It turns one USB-C port into two 3.5 mm outputs with a built-in DAC chip, so two people can share audio from one phone, tablet or laptop.
• ZOOAUX PRO USB C — biggest trade-off: It's an adapter, not earbuds — you supply your own headphones, it doesn't support microphones, and it won't charge your device.
• Who each pick is for: JVC ORANGE GUMY is for one person who wants cheap, comfortable wired earbuds; ZOOAUX PRO USB C is for two people sharing a screen on a modern USB-C device.
The JVC ORANGE GUMY (model HAFX7D) is a straightforward pair of wired in-ear earbuds. The design is about as simple as it gets: round in-ear housings with silicone tips, a 3.3 ft colored cord, and a standard 3.5 mm headphone jack. There's no battery, no pairing, no charging case, and no app. You plug them in and you're listening. For a lot of people, that's exactly the point.
Where the GUMY earns its keep is fit and comfort. JVC includes small, medium and large ear tips in the box, so you can swap until the seal feels right — and a proper seal is what gives you the deeper bass and clearer treble the design is aiming for. The soft, color-matched silicone tips and the light in-ear shape make these a natural pick for the gym, a run, or a commute where you don't want to worry about an expensive pair getting yanked out or lost. The "Sports and Exercise" styling and sound-isolation approach fit that use case well: the tips block some outside noise passively, and there's a wired media control for basic playback.
In my opinion, the GUMY is the right buy if you want one dependable pair of earbuds for workouts, calls-free listening, and everyday phone use, and you're plugging into a device with a 3.5 mm jack — an older phone, a laptop, a tablet, a handheld console, an in-flight entertainment system. It's also the better choice if you tend to lose or break earbuds, since a spare set costs little and there's no charging to think about.
Who should skip it? Anyone whose phone or tablet has dropped the headphone jack entirely, and anyone who wants to share audio with a second person. The GUMY is a one-person, one-jack product — if your device only has USB-C, this isn't the tool for the job.
The ZOOAUX PRO USB C is a different category of product altogether. It's a USB-C to dual 3.5 mm splitter — a 1-in-2-out adapter that lets two people listen from a single USB-C port. You plug it into the USB-C port on a phone, tablet or laptop, then plug two sets of 3.5 mm headphones into the two outputs. That's it. No drivers, no setup, no pairing.
The headline feature is the built-in DAC chip. A lot of cheap splitters just passively split the signal, which tends to drag volume down and add noise. ZOOAUX PRO's design routes the digital audio through its own converter so both outputs get clean stereo sound without the volume loss you'd expect from a passive split. If you've ever tried a bargain splitter and been disappointed, that's the difference this adapter is built to address.
Compatibility is broad on the USB-C side: it's listed as working with recent iPhone 15/16/17 models, iPad Pro/Air/Mini, Samsung Galaxy S23 through S26, Google Pixel, MacBook, and most USB-C laptops. The build is more serious than the price-point category usually suggests — a nylon-braided jacket to resist tangling, reinforced strain relief, and an aluminum alloy housing at the connectors. ZOOAUX PRO also states it has passed a 25,000+ plug-and-unplug durability test, and it's backed by a warranty with 24/7 customer service.
Now the honest limitations, because they matter. This adapter does not support microphone function, so it's for listening only — no headset mics. It does not charge your device while in use. It works with TRS headphones and is not compatible with TRRS ports. And it explicitly won't work with a Nintendo Switch. So it's not a universal audio dongle; it's a sharing tool.
Who is it for? In my opinion, it's ideal for couples or friends watching a movie on a tablet on a flight, two kids sharing a lesson on one laptop, or a road trip where two people want the same playlist without passing earbuds back and forth. It's also a neat fix for a modern phone that dropped its headphone jack but where you want to run wired headphones with a friend. Skip it if you need a mic, need charging passthrough, or want earbuds included — it's an adapter only.
Side-by-Side: Which Should You Choose?
• Best for sharing audio between two people → ZOOAUX PRO USB C. Its whole purpose is a 1-in-2-out split from one USB-C port.
• Best for modern USB-C-only phones and tablets → ZOOAUX PRO USB C. The GUMY needs a 3.5 mm jack that many new devices no longer have.
• Best for workouts and active use → JVC ORANGE GUMY. In-ear silicone tips, sound isolation, and no adapter to snag.
• Best for clean sound on a split → ZOOAUX PRO USB C. The built-in DAC is the reason to choose it over a passive splitter.
• Best for durability in daily plugging → ZOOAUX PRO USB C. Nylon-braided cable, aluminum housing, and reinforced strain relief.
• Best for listening only, no mic → ZOOAUX PRO USB C. Remember it does not support microphone function or charging.
• Best for a single listener with older gear → JVC ORANGE GUMY. A laptop, older phone, or console with a headphone jack is all it needs.
If I had to pick just one, I'd buy the JVC ORANGE GUMY — but only because I'd be buying it for myself, one person, one pair of ears, listening on a device that still has a headphone jack. For that job it's the more complete, more comfortable, more forgiving product, and there's nothing to charge. I'd choose the ZOOAUX PRO USB C the moment my goal shifted to sharing sound from a USB-C port with someone else, or to running wired headphones off a phone that no longer has a jack. They're both good at what they do; they just don't do the same thing. Check the current price on Amazon for whichever matches your setup before you commit.
FAQ
No. It's an adapter only — you supply your own 3.5 mm TRS headphones. The JVC ORANGE GUMY, by contrast, is a complete pair of earbuds with small, medium and large ear tips included.
Not directly. The GUMY uses a standard 3.5 mm jack, so it needs a device with a headphone input. If your phone is USB-C only, the ZOOAUX PRO USB C is the one that connects — just remember it doesn't support mics or charging.
Yes — that's its main feature. It splits one USB-C audio source into two 3.5 mm outputs so two people can listen together. Just note it won't work with a Nintendo Switch and doesn't support TRRS headsets.
Start with whichever matches your device. If you have a headphone jack and want earbuds, look at the JVC ORANGE GUMY; if you have USB-C and want to share audio, look at the ZOOAUX PRO USB C. The page's price button will show you the current figure for each.
