If you want to turn a modern USB-C phone, tablet or laptop with no headphone jack back into a wired-listening device, choose JXMOX USB Type C; if you need to plug two pairs of headphones into one old-school 3.5mm jack so two people can listen at once, choose SAMZHE Headphone Splitter 3.5mm. These two cables look vaguely similar in a product photo, but they solve completely different problems, and picking the wrong one is the fastest way to end up with a dongle you never use.
• JXMOX USB Type C — biggest strength: it converts a USB-C port into a working 3.5mm output with a built-in DAC chip, so a phone or laptop that dropped the headphone jack can drive wired headphones again.
• JXMOX USB Type C — biggest trade-off: it only works on the USB-C devices listed in its compatibility list, and its two units are identical adapters rather than two different functions.
• SAMZHE Headphone Splitter 3.5mm — biggest strength: it splits one 3.5mm output into two, so two people can share audio from the same source — and the slim plug fits most phone cases.
• SAMZHE Headphone Splitter 3.5mm — biggest trade-off: it is audio-out only; there is no microphone input and no inline volume control support, and it needs a device that already has a 3.5mm jack.
• Who each pick is for: JXMOX is for the person whose device has no headphone jack at all; SAMZHE is for the person whose device has a jack but only one of them.
The JXMOX USB Type C is a 2-pack of USB-C-to-3.5mm-female adapters, each about 11 cm long and weighing roughly 9 grams. The core of it is a built-in DAC chip that converts digital audio into an analog signal for your headphones. According to the specs, that chip supports up to 16-bit/48 kHz sampling, draws low power, and is paired with noise-reduction design meant to keep music clean. It also passes through the wire-control functions your headset already has — microphone, volume and pause/play — so it behaves like the headphone jack your phone used to have.
Build quality is a genuine selling point here. The shell is ABS with a nylon-braided cable, and JXMOX rates it for 20,000+ bends, with shielded enamel wire inside to keep the signal stable through daily pocket-and-bag abuse. That matters, because a dongle lives in exactly the environment that kills cheap cables.
Who should buy it: anyone on a USB-C phone, tablet or laptop with no 3.5mm jack — the compatibility list covers recent iPhone 15/16/17 family models, Samsung Galaxy S20 through S25 Ultra, Note models, iPad Pro, iPad mini 6, iPad Air 4, MacBook, Google Pixel 2/3/4 XL and several OnePlus and Huawei models. The 2-pack is the quiet advantage: one for the bag, one for the desk, so you stop re-buying them. Who should skip it: anyone whose device still has a real headphone jack and just wants to share audio with a second person — this won't do that at all.
The SAMZHE Headphone Splitter 3.5mm is a Y-cable: one male 3.5mm plug into your device, two female 3.5mm sockets out. It's a 25 cm (9.8 inch) tangle-free cable weighing about 10 grams, and its whole job is letting two people listen from one source — two sets of headphones, or a pair of speakers fed from the same jack.
The construction is deliberately better than the throwaway splitters you find in bargain bins. SAMZHE uses 24K gold-plated connectors, oxygen-free copper inner conductors and triple shielding to keep static and signal loss out of both outputs. The housing is aluminum alloy, the cable is flexible TPE, and there are strain-relief rings at the joints to survive repeated twisting and pulling. The connector is also slim enough to fit most phone cases without taking the case off — a small detail, but a real one if you've ever fought a thick plug against a case lip.
Who should buy it: anyone sharing audio in the real world — two people on a plane with one tablet, gaming on a PS5/PS4/Switch/Xbox, a car stereo or laptop with a single aux jack. The compatibility list spans iPhone 6/5/4/SE, older Galaxy S-series, MacBook, Surface, Huawei, Sony, LG, Xiaomi and more, plus speakers, soundbars and amplifiers. Who should skip it: anyone who needs a microphone or inline volume control to work through the split. SAMZHE states plainly that both female ports are audio-output only, and that this splitter does not support mic input — so it's wrong for a headset with a boom mic, or for a headset whose volume buttons you rely on.
• Best for a phone with no headphone jack → JXMOX USB Type C. Without a USB-C port in play, the SAMZHE cable has nothing to plug into.
• Best for sharing audio between two people → SAMZHE Headphone Splitter 3.5mm. One jack becomes two; the JXMOX adapter does not split anything.
• Best for wired headset calls and mic use → JXMOX USB Type C. It supports wire control and microphone functions; the SAMZHE is audio-out only.
• Best for listening on a laptop or tablet that still has a 3.5mm port → SAMZHE Headphone Splitter 3.5mm. No adapter or chip needed at all.
• Best for long-term durability → a tie, by different methods. JXMOX rates its braided cable for 20,000+ bends; SAMZHE leans on aluminum housing, strain-relief rings and triple shielding.
• Best for case-on phones → SAMZHE Headphone Splitter 3.5mm. Its slim plug is designed to fit most protective cases without removal.
• Best for travel and storage → JXMOX USB Type C. At 11 cm folded into a braided cord, it disappears into a pocket; the splitter is a 25 cm Y-cable, which is still small but does dangle.
• Best for retro and console gear → SAMZHE Headphone Splitter 3.5mm. PS5, PS4, Switch, Xbox 360, car stereo, soundbar — all standard 3.5mm territory.
• Best two-in-one value → JXMOX USB Type C. It ships as a 2-count, so you get a spare of the exact cable you're most likely to lose.
In my opinion, the right buy comes down to one question: does your device have a headphone jack? If it doesn't, I'd take the JXMOX USB Type C — a built-in DAC, 16-bit/48 kHz support, mic and volume passthrough, a 20,000+ bend rating, and a spare in the box make it the more useful cable for modern phones and laptops. If your device does have a 3.5mm jack and you want two people listening at once, I'd take the SAMZHE Headphone Splitter 3.5mm — gold-plated, triple-shielded and case-friendly. Buy for your port situation, not for the shape of the cable. And check the current price on Amazon before you commit, since that's the one spec that changes.
No. JXMOX converts a USB-C port into one 3.5mm output using a built-in DAC. SAMZHE takes an existing 3.5mm output and splits it into two. Different problems, different cables.
The mic won't work. SAMZHE states both female ports are audio-output only, and the splitter does not support microphone input or inline volume control, so use it with plain headphones or speakers.
It works with the USB-C devices JXMOX lists — recent iPhone 15/16/17 models, Galaxy S20 through S25 Ultra, Note series, iPad Pro, iPad mini 6, iPad Air 4, MacBook, Pixel 2/3/4 XL and some OnePlus and Huawei models. If your phone still has a round headphone jack, this adapter isn't for you.
The SAMZHE splitter, assuming the tablet or phone you're using has a 3.5mm jack. Plug it in, connect two sets of headphones, and you're both listening — no drivers, no setup. If your device is USB-C only, you'd need a USB-C audio adapter first.
