JXMOX USB C vs WUNIAK Charging Cable at a Glance
• JXMOX USB C — biggest strength: it turns a single USB-C port into two, giving you a 3.5mm audio jack plus a USB-C pass-through that supports PD charging up to 60W, so music and power stop competing for the same hole.
• JXMOX USB C — biggest trade-off: it does no data transfer at all, and Quick Charge isn't guaranteed on some newer phones — JXMOX itself points you toward a PD wall charger for the fastest results.
• WUNIAK Charging Cable — biggest strength: a purpose-built magnetic replacement cable for MARLALL S800 / LOBKIN X7 swimming headphones, sold as a two-pack, with a PTC voltage regulator inside to guard against overcurrent.
• WUNIAK Charging Cable — biggest trade-off: it charges those two headphone models and essentially nothing else. There's no audio function, no USB-C plug, and the 60cm length is deliberately short.
• Who each is for: JXMOX for anyone with a USB-C phone or tablet and a wired pair of headphones they refuse to give up; WUNIAK for someone who already owns those swimming headphones and has lost or frayed the original cable.
This is a Y-splitter with brains. One end goes into your USB-C port, and the other end splits into a 3.5mm aux jack and a female USB-C port that accepts a PD charger up to 60W. JXMOX builds in a DAC chip to convert the digital signal to analog, and the spec sheet describes that chip as low-power with stable decoding — the practical upshot being that your headphones get a clean stereo signal instead of the thin, noisy output you sometimes get from cheap pass-through dongles. It's plug and play, no drivers, no setup. Grey, tiny, about 0.01 kg, the kind of thing that disappears into a pocket and you forget about until you need it.

Where it earns its place is in real, slightly annoying situations. Long-haul flights where the seat screen still wants a 3.5mm plug but your phone needs to stay topped up. Desk setups where you're on calls for hours and don't want to babysit battery percentage. Wired gaming on a phone or iPad Pro, where a cable still beats Bluetooth for latency. And yes — for glasses wearers, it's the piece that lets you keep using an over-ear pair whose pads you've finally got sitting comfortably around your frames, instead of switching to buds that press on your temples.
Who should skip it? Anyone who needs to move files — JXMOX states plainly that data transfer isn't supported. Anyone on certain OnePlus models, since compatibility there is explicitly partial. And anyone hoping for Quick Charge on a brand-new phone: the manufacturer recommends a PD charger and warns QC may not work on some recent handsets. If you want a charging cable for swimming headphones, this isn't it — not remotely.
The WUNIAK cable solves one narrow problem well: you own MARLALL S800 or LOBKIN X7 swimming headphones, and the magnetic charging cable that came with them is lost, chewed, or dead. This is the drop-in replacement. It's a four-pin, male-to-male magnetic connector on a 60cm copper lead, black, about 1.6 ounces, and it charges from a laptop USB port, a PC, or a wall adapter. Because the connection is magnetic, it snaps on rather than plugs in — which is exactly what you want on a device that lives near water and gets handled with wet hands.
The detail I actually like here is the PTC voltage regulator inside. Overcurrent is a quiet killer of small Bluetooth devices, and a cheap cable with no protection is a gamble against a device you presumably like. WUNIAK also points out that the 60cm length is intentional — short enough to coil into a swim bag or leave in a car cubby. You get two cables in the pack, which is a sensible way to sell a spare: one for home, one that lives in the kit bag.
The trade-off is blunt. This cable only fits those swimming headphone models. It won't charge your phone, it won't carry audio, and it isn't a USB-C anything. If you don't own a MARLALL S800 or a LOBKIN X7, there is no reason to buy it. If you do own one, it's the only sensible thing on this page for you.
• Best for listening and charging at the same time → JXMOX USB C. Two ports out of one, with PD charging up to 60W running alongside the audio.
• Best for a phone with no headphone jack → JXMOX USB C. That's the entire point of the product.
• Best for glasses wearers who want to keep their over-ear pair → JXMOX USB C. You aren't hunting for the best usb c charging over ear headphones for glasses wearers; you're keeping the pair that already fits your frames and adding a jack.
• Best for anyone who owns MARLALL S800 or LOBKIN X7 swimming headphones → WUNIAK Charging Cable. Two cables, magnetic connection, overcurrent protection.
• Best for a travel or gym bag spare → WUNIAK Charging Cable, if and only if you own those headphones. The 60cm length and two-pack format are built for that.
• Best for audio quality on a budget-minded dongle → JXMOX USB C. The DAC chip and stable decoding are the reason to pick it over a bare splitter.
• Best if you need data transfer → neither. JXMOX explicitly excludes it; WUNIAK is a charging lead, full stop.
In my opinion, JXMOX USB C is the one to buy — it's the product that works for more people, and it's the one I'd hand to a glasses wearer who's tired of choosing between comfortable headphones and a charged phone. The 60W PD pass-through plus a real DAC chip in something this small is a genuinely useful combination, and the limitations (no data, QC caveats, partial OnePlus support) are clearly stated rather than hidden. I'd only steer you to the WUNIAK cable if you specifically own MARLALL S800 or LOBKIN X7 swimming headphones and need a spare — in that case it's the right answer, and the PTC protection makes it a smarter buy than a no-name lead. Everyone else: the best foldable headphone for glasses wearers in your drawer still needs a 3.5mm hole to plug into, and JXMOX gives it one.
FAQ
Yes — that's its core function. One USB-C port in, a 3.5mm jack and a PD charging port out, with charging supported up to 60W. Just note it passes power and audio only, never data.
No. It's a four-pin magnetic cable made for MARLALL S800 and LOBKIN X7 swimming headphones. It won't fit a phone, a USB-C device, or any other brand of headphone.
Decide by what's in your bag: a USB-C phone plus wired headphones means JXMOX; a pair of those swimming headphones means WUNIAK. On cost, check the current price on Amazon — the button on this page takes you straight there.
