If you want to keep using your favorite wired headphones with a modern USB-C phone that has no headphone jack, choose JXMOX USB Type C; if you need to run audio between two devices that both have a round 3.5mm port — a phone and a car stereo, a laptop and a speaker — choose RIKSOIN Aux Cable-3.5mm.
• JXMOX USB Type C — biggest strength: it converts a digital USB-C output into a working 3.5mm headphone jack with a built-in DAC, so you get wired listening, mic support and in-line controls back on a phone that dropped the port.
• JXMOX USB Type C — biggest trade-off: it only helps USB-C devices with no headphone jack, and it's a tiny adapter you can easily misplace — though this listing is a 2-pack, which softens that.
• RIKSOIN Aux Cable-3.5mm — biggest strength: a 6.6 ft male-to-male 3.5mm cable with oxygen-free copper, gold-plated plugs, double shielding and two magnetic anti-interference rings for a clean, hum-free run between two aux ports.
• RIKSOIN Aux Cable-3.5mm — biggest trade-off: both ends must already be 3.5mm — it does nothing for a phone with only a USB-C port. Length is fixed at 6.6 ft.
• Who each is for: JXMOX for USB-C phone, tablet, iPad or MacBook owners with wired headphones; RIKSOIN for car stereos, home stereos, speakers and any two 3.5mm devices.
This is a small USB-C-to-3.5mm-female adapter, and the whole point is the DAC chip inside it. Phones, tablets and laptops that only expose audio over USB-C can't drive analog headphones directly — the JXMOX does that digital-to-analog conversion for you. In my reading of the specs, the useful bit is the stated support for up to 16-bit/48kHz sampling and low power draw, which is exactly the range you want for everyday streaming and calls rather than a power-hungry audiophile dongle.
The feature set is broader than "just audio out." It carries microphone and in-line control passthrough, so pause/play and volume buttons on a wired headset keep working, and you can take calls through the headset mic. Build-wise it's an ABS shell with nylon-braided cable, and the listing claims a 20000+ bend rating plus shielded enamel wire to keep the signal stable. It's about 11cm long and weighs roughly 9 grams — genuinely pocket-sized. No drivers, no setup: plug it in and it works.
Who should buy it: anyone with a USB-C-only phone, iPad Pro/mini/Air, or MacBook who still prefers wired headphones, and who wants mic and remote support rather than a bare listen-only dongle. Compatibility is listed broadly across iPhone 15/16/17 families, Galaxy S20 through S25, Note, Pixel, OnePlus and more. Who should skip it: if your device still has a real headphone jack, you don't need this at all — and if you're trying to connect two 3.5mm devices, this is the wrong product entirely. It's also a 2-pack, which is handy if you want one for a bag and one for a desk.
This is a classic 3.5mm male-to-male aux cable, 6.6 ft long, and it's built for the job most people actually use aux cables for: getting audio from one device into another over a short-to-medium run. The headline design choice is the pair of magnetic rings — ferrite-style anti-interference components that suppress high-frequency noise. In practical terms that's the kind of thing that helps when a cable runs near power or a car's electronics and you'd otherwise hear a faint hiss or hum. The listing also calls out oxygen-free copper conductors, 24K gold-plated connectors and double shielding, all of which are standard, sensible choices for keeping signal loss and corrosion low.
Durability and handling are the other story here. The jacket is nylon braided and the cable is rated for a 15000+ bend lifespan, with a tangle-free, roll-up-friendly feel. It's a male-to-male cable, so it connects two jacks — it doesn't adapt anything. Think phone or tablet into a car stereo, laptop into a powered speaker, MP3 player into an amplifier or soundbar.
Side-by-Side: Which Should You Choose?
• Best for phones with no headphone jack → JXMOX USB Type C. It restores wired listening where the port is missing.
• Best for car stereos and speakers → RIKSOIN Aux Cable-3.5mm. Male-to-male 3.5mm is exactly the car-aux use case.
• Best for mic and call support → JXMOX USB Type C. It passes through microphone and in-line controls; the RIKSOIN is audio-only.
• Best for cable length → RIKSOIN Aux Cable-3.5mm. 6.6 ft of reach versus an ~11cm adapter.
• Best for portability → JXMOX USB Type C. Around 9 grams, toss it in a pocket or bag.
• Best for noise suppression on a long run → RIKSOIN Aux Cable-3.5mm. The two magnetic rings and double shielding target interference directly.
• Best for connecting two 3.5mm devices → RIKSOIN Aux Cable-3.5mm. That's its entire purpose.
• Best if you want a spare → JXMOX USB Type C. It ships as a 2-pack, so you get a backup.
If I had to pick one, it would depend entirely on the ports you own — but forced to choose for the most common modern situation, I'd buy the JXMOX USB Type C. The reason is simple: the headphone jack is the thing that's disappearing, and this adapter solves the problem most people actually have right now — a USB-C phone and a pair of wired headphones, with mic and controls intact. If your world is 3.5mm-to-3.5mm — car, stereo, speaker — then in my opinion the RIKSOIN Aux Cable-3.5mm is the smarter, more honest tool for that job. Check the current price on Amazon for whichever fits your setup.
Yes, per the listing it's compatible with those USB-C iPhone models and supports audio plus mic and in-line controls. If you want to keep using wired headphones, it's the relevant accessory.
No. It's a male-to-male 3.5mm cable, so both devices need a 3.5mm port. A phone without one would need a USB-C adapter like the JXMOX in between.
They do different jobs. The JXMOX relies on a DAC rated up to 16-bit/48kHz for digital-to-analog conversion; the RIKSOIN leans on oxygen-free copper, gold-plated plugs, double shielding and magnetic anti-interference rings to keep an analog signal clean. Match the cable to your port type and needs.
The JXMOX adapter is about 11cm with a 20000+ bend rating; the RIKSOIN is 6.6 ft with a 15000+ bend rating and a tangle-free nylon jacket. Both are built for daily handling.
