• JXMOX USB C — biggest strength: it splits one USB-C port into a 60W PD charging pass-through plus a 3.5mm audio jack, so charging and listening happen at the same time.
• JXMOX USB C — biggest trade-off: it is an adapter, not a headphone. You still need your own 3.5mm earphones, and it does not move data.
• LUDOS OMNITONE — biggest strength: a finished product — wired in-ear headphones with a microphone, call controls, a 3.5mm plug and a protective case.
• LUDOS OMNITONE — biggest trade-off: it is a passive 3.5mm wired set, so it brings no charging function of its own and needs a phone that either has a headphone jack or is paired with an adapter.
• Pick JXMOX USB C if your phone dropped the headphone jack but you refuse to give up wired audio while charging.
• Pick LUDOS OMNITONE if you just want earphones that work, with a mic for calls and a warranty behind them.
The JXMOX USB C adapter solves one very specific, very modern annoyance. Most current phones — think iPhone 15 through 17, Galaxy S25 and S24 families, Pixel 7 and up, iPad Pro and iPad Air — have exactly one USB-C port and no headphone jack. That means charging and wired listening compete for the same hole. This dongle ends that fight. It turns the single port into two: a PD charging port rated up to 60W and a 3.5mm aux jack, so you can play games, take calls, or watch video on wired headphones while the battery is still topping up.
Inside, JXMOX uses a DAC smart chip. In plain terms, that chip converts the digital audio signal from your phone into the analog signal your headphones understand, and it's built to run at low power with stable decoding. That's the part that matters for sound: a good DAC keeps the signal clean and keeps background hiss down. There's also a charging chip that steadies voltage and current, which is the boring-but-important job of not stressing your phone's battery. Setup is genuinely nothing — no app, no driver, plug and play.
Who should buy it? Two groups. First, people with a USB-C phone and a favorite pair of 3.5mm headphones they refuse to replace. Second, anyone who games or takes long calls on a phone that would otherwise be dead by hour three. Who should skip it? If you already own wireless headphones you're happy with, this is a solution to a problem you don't have. And if you need to move files, look elsewhere — this adapter explicitly does not support data transfer. One honest quirk worth knowing: if you unplug the power while music is playing, the audio can stop, because the control chip restarts when the power supply changes. Just hit play again. For a small grey dongle weighing next to nothing, it does a surprisingly specific job very well.
The LUDOS OMNITONE is a different kind of product entirely — not an accessory that enables headphones, but the headphones themselves. They're wired in-ear buds with a turquoise finish, rounded tips, and metal in the enclosure. Inside sits a dynamic driver covering 20 Hz to 20,000 Hz, which is the full audible range, with 32 ohm impedance. That impedance number is the practical one: 32 ohm is easy to drive, so these will run at normal volume from a phone, a laptop, a school Chromebook, basically anything with a 3.5mm jack.
They're built for talking as much as listening. There's a built-in microphone, call control, and a button controller on the cable. Sound isolation is listed as the noise-control approach — meaning the tips physically block some surrounding noise rather than using electronics to cancel it. In a noisy house or a shared classroom, that's the honest, no-battery way to do it. You also get a protective case in the box, and a warranty that runs far longer than most people keep a pair of earbuds.
Who should buy them? Students, kids, remote workers on video calls, and anyone who wants a simple wired set that doesn't need charging, pairing, or an app. The 3.5mm plug means zero latency, which matters if you're editing audio or gaming. Who should skip them? If your phone has no headphone jack and you don't want a dongle, these alone won't connect — you'd need something like the JXMOX adapter to bridge the gap. And if you want active noise cancellation, this isn't that; it's isolation through fit.
Side-by-Side: Which Should You Choose?
• Best for charging while listening → JXMOX USB C. It's the only one of the two that passes power through to your phone.
• Best for making calls → LUDOS OMNITONE. Built-in mic and call control on the cable, no adapter required.
• Best for phones, laptops and tablets with a 3.5mm jack → LUDOS OMNITONE. Plug straight in, 32 ohm, easy to drive.
• Best for travel and school bags → LUDOS OMNITONE. A complete set with a protective case beats a bare adapter you'll lose.
• Best for gamers and video callers who hate latency → either, but for different reasons. JXMOX keeps you wired and charged; OMNITONE gives you a mic and controls in one cable.
• Best for long-term peace of mind → LUDOS OMNITONE. The warranty coverage is the standout spec here.
• Best if you already own great wired headphones → JXMOX USB C. Don't rebuy what you love; just make it work with your new phone.
In my opinion, the JXMOX USB C adapter is the smarter buy for most people reading a fast-charge comparison, because it fixes the exact problem that pushed you to search: one port, two needs. It's the piece of gear that lets a modern phone behave like an old one — wired audio in, power in, at the same time, up to 60W. That said, if you don't already own a decent pair of 3.5mm headphones, the LUDOS OMNITONE is the more complete purchase out of the box. Buy the JXMOX if you have headphones; buy the OMNITONE if you need them.
how to charge headphones faster
Charging speed depends on the charger and the headphone's own limit, not on the cable alone. With the JXMOX USB C adapter, the practical tip is to use a PD wall charger rather than a Quick Charge brick — JXMOX notes that some newer phones may not support QC through the adapter, and PD is the recommended path to faster charging.
how to charge headphones
For wired earbuds like the LUDOS OMNITONE, there's nothing to charge — they're passive 3.5mm headphones that draw no power. For wireless headphones, you charge them through their own charging port or case. The JXMOX adapter matters because it keeps your phone charging while you're still listening on wired audio.
is fast charging bad for headphones
The short answer from the specs here: the JXMOX adapter includes a chip specifically to stabilize charging voltage and current to protect your devices, which is exactly the safeguard you'd want. Fast charging is designed around the device's own power management, so using a PD charger rated within the adapter's 60W ceiling is the intended, protected use case.
does the JXMOX adapter work with the LUDOS OMNITONE
Yes, in principle — the JXMOX gives you a 3.5mm audio jack, and the OMNITONE has a 3.5mm plug. That combination lets you use the LUDOS earbuds on a USB-C phone that has no headphone jack, while still charging the phone through the adapter's PD port. Just remember the adapter doesn't pass data, and audio may pause if you unplug power mid-song.
