• Elecan's biggest strength: It's a true extension cable — male 3.5mm to female 3.5mm — so it lengthens whatever aux wired headphones, speakers or car stereos you already own instead of replacing them.
• Elecan's biggest trade-off: It's a passive TRS cable with three pins, so TRRS headphones with a mic may lose microphone function, and it only makes sense if both ends of your setup are already 3.5mm.
• SNANSHI's biggest strength: It converts a USB-C device into a 3.5mm aux source using a built-in DAC chip, and the two-pack gives you one 90-degree right-angle plug for tight car consoles plus one straight plug for desk and home stereo use.
• SNANSHI's biggest trade-off: It's strictly audio-output-only — no calls, no mic, no inline volume or play/pause buttons, no charging, no data — and it will not fit Lightning iPhones (14/13/12/11/SE) or USB-A ports.
• Pick Elecan if your problem is "my cable is too short."
• Pick SNANSHI if your problem is "my phone has no headphone jack."
Elecan's cable is built around one very specific annoyance: you're tethered to your desk, your car stereo or your home theater because the headphone cable that came with your gear is too short. This is a 2-foot, 2-pack male-to-female 3.5mm AUX extender, so it slots in between your existing headphones and your existing source. Nothing about your audio chain changes — you just get more slack.
The design details matter more than they look. The outer diameter is only 3.5mm, thinner than most aux cables, which makes it unusually flexible and lets it thread through narrow openings — a jacket sleeve, a desk grommet, the gap behind a car console. The stepped connector is shaped so it won't get stuck when your phone is wearing a thicker case. Inside, it's a pure copper core with 24K gold-plated connectors, and Elecan rates it for 15,000+ plug-in cycles plus 10,000+ bending cycles in the description. The jacket is nylon braid over a zinc alloy shell, so it resists tangling and fraying. Elecan also backs it with a 2-year refund-or-replacement warranty.
SNANSHI Aux: Who It's For
SNANSHI solves the opposite problem. You have a USB-C device — an iPhone 17/16/15 series, an iPad Pro or Air, a Galaxy S25/S24, a Pixel — and you want to feed audio into something with a 3.5mm aux input: an older car stereo with no Bluetooth, a home speaker, a stereo receiver, or a pair of wired headphones. This cable has a built-in DAC chip that turns the digital USB-C output into an analog 3.5mm signal, and SNANSHI describes the result as clean and static-free.
The two-pack is the smart part. You get one 90-degree right-angle USB-C plug, which sits flush and reduces bending in cramped car center consoles, and one straight plug, which is easier for desk setups, home stereos and headphones. The cable is 3.3 feet, wrapped in nylon braid with an aluminum alloy shell and reinforced strain relief, rated to 15,000+ bends.
Now the limits, and they are real. This is a 3-pole TRS audio-output-only cable. It does not make or receive calls — there's no mic path — so voice commands and recording won't work through it. It does not support inline volume, play/pause or skip buttons; you control playback on the device itself. It does not charge and does not transfer data. And it will not fit Lightning iPhones (iPhone 14/13/12/11/SE) or USB-A ports.
Who should buy it: anyone whose phone lost the headphone jack and who wants wired playback in a car or on a home stereo with zero pairing, apps or adapters. Skip it if you need hands-free calling — SNANSHI itself points you to Bluetooth for that — or if you're still on a Lightning iPhone. Check your charging port before ordering.
Side-by-Side: Which Should You Choose?
• Best for extending existing aux wired headphones → Elecan Headphone Extension Cable. It's male-to-female 3.5mm, so it adds length without touching your signal chain.
• Best for USB-C phones with no headphone jack → SNANSHI Aux. The built-in DAC chip is the whole point.
• Best for threading through narrow gaps, cases and grommets → Elecan Headphone Extension Cable. A 3.5mm outer diameter and stepped connector are built for exactly that.
• Best for frequent plugging and unplugging → Either. Both are rated for 15,000+ cycles or bends; Elecan adds a 2-year warranty.
• Best for calls, mic or inline buttons → Neither. Elecan may drop mic function on TRRS headphones, and SNANSHI is playback-only by design.
• Best for a single purchase that covers car and desk → SNANSHI Aux. Two plugs, two shapes, one pack — assuming your source is USB-C.
• Best for old iPods, MP3 players, laptops and non-USB-C gear → Elecan Headphone Extension Cable. It's the only one of the two that works with a plain 3.5mm jack on both ends.
In my opinion, most people searching this comparison fall into one of two camps, and you already know which one you're in. If your gear has a 3.5mm jack and you just need more reach — especially with a thick phone case or a cramped setup — I'd buy the Elecan Headphone Extension Cable. It's the more universally useful of the two, it comes as a 2-pack, and the 2-year warranty is the kind of thing I like to see on a cable that gets yanked around daily. I'd only go with SNANSHI Aux if your source device is USB-C and your destination is a 3.5mm aux input, and you accept that calls and inline controls are off the table. Check the current price on Amazon before you commit, since both are inexpensive enough that the two-pack math matters.
how to make aux cable with headphones
You don't need to build anything. If your headphones end in a 3.5mm plug and your source has a 3.5mm jack, the Elecan Headphone Extension Cable simply inserts between them — male end into the device, female end into your headphones — and extends the run by 2 feet per cable. If your source is USB-C instead, the SNANSHI Aux cable replaces that connection entirely with its USB-C plug on one end and 3.5mm on the other.

If your phone still has a 3.5mm jack, plug straight in, or add the Elecan Headphone Extension Cable if the cable is too short. If your phone is USB-C only, use the SNANSHI Aux cable, which converts the USB-C port to a 3.5mm output through its DAC chip. If you're on an older Lightning iPhone, neither cable fits — you'd need a Lightning-specific adapter, and both cables here are the wrong connector for that.
do these cables support microphone or volume controls?
No, and this is the detail buyers miss most. SNANSHI states plainly that its cable is a 3-pole TRS audio-output-only design with no mic path and no inline control circuit, so calls, voice commands, recording, volume and play/pause buttons won't work through it. Elecan's extender is a 3-pin TRS cable too, and Elecan warns that TRRS 4-core headphones may lose microphone functionality when extended. For hands-free calling, Bluetooth is the practical route.
