How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, tangle-free extender that also protects your phone's headphone jack from constant plugging and unplugging, choose Ugreen Headphone Extension Cable; if you need a longer run that keeps your inline microphone and remote buttons working, choose KabelDirekt.
• Ugreen's biggest strength: a slim, step-down male connector that fits through a thick phone or tablet case, plus a 10 ft tangle-free round cable aimed at everyday mobile listening.
• Ugreen's biggest trade-off: it is a 3-pole TRS cable — audio only. If your headset has a mic, the audio still plays but the microphone will not work.
• KabelDirekt's biggest strength: it is built as a CTIA-standard headset extension, so inline mic and remote functions like play, pause and next keep working, over a 20 ft run.
• KabelDirekt's biggest trade-off: it is a heavier, bulkier cable with a metal-shelled plug, and it is longer than many desk or car setups actually need.
• Pick Ugreen if you mostly listen to music or podcasts from a phone, tablet or car stereo and want a case-friendly, pocketable extension.
• Pick KabelDirekt if you take calls, game with a headset, or need the extra reach across a room.
The Ugreen cable is a 3.5mm male-to-female stereo extension — 3-pole TRS, 10 feet long, round, and finished in black. What stands out in the spec sheet is the connector design. The step-down housing is deliberately slim so it can pass through a phone or tablet case without you having to peel the case off every time you want to plug in. That is a small thing on paper and a genuinely annoying thing in daily life, and it is the detail Ugreen clearly designed around.
The build is aimed at clean, uncolored stereo sound: 24K gold-plated connectors for corrosion resistance, double shielding, and high-purity copper conductors. Ugreen also pitches this cable as a jack protector — the idea being that a cheap extension takes the wear of repeated plugging instead of the port on your device. That is a sensible habit if you plug and unplug headphones a lot, whether on a commute, at a desk, or in a car with an aux input. The tangle-free round jacket and the light weight (the sheet lists it at a fraction of a gram, which tells you it is a thin, flexible cable rather than a stiff one) make it easy to coil and stash.
Here is the catch, and it is the one that matters most. This is explicitly an audio-only cable. If you plug a TRRS headset — the kind with a built-in microphone — into it, you will hear sound, but the mic will not work. So Ugreen fits you if you listen: music, podcasts, audiobooks, a car stereo, a speaker, a soundbar, an amp. It does not fit you if you take calls, join meetings, or use voice chat with a headset. In my opinion, that single limitation is what decides this comparison for most people.
KabelDirekt takes the opposite approach. This is a 20 ft CTIA-standard headset extension cable, and the word "headset" is doing real work in that sentence. Because it is wired to CTIA spec, it does not just pass audio — it supports inline headset functions like next track, pause, play and microphone. If your wired headset has a little inline remote, this cable is designed to keep that remote alive at the far end of the extension. That is the feature Ugreen simply does not offer.
The construction is heavier and more protective. A nearly break-proof metal shell wraps the solder points of the plug, which is exactly where cheap extension cables tend to fail after months of yanking and bending. The female connector is built for a tight, interference-free fit, and the PVC jacket protects high-purity copper conductors while staying flexible rather than rigid. End-to-end shielding and gold-plated connectors round out the signal path. KabelDirekt also backs it with a 36-month manufacturer's warranty — worth noting, though the sheet also lists a shorter 18-month warranty figure elsewhere, so treat the longer number as the manufacturer's headline claim rather than a certainty you should bank on.
At 20 ft and roughly 150 g, this is not a cable you forget is in your bag. It is a cable you run once and leave in place: from a desktop PC or laptop to a headset across the room, from a Hi-Fi stack to a couch, from a TV or amplifier to a chair. The compatibility list is broad — smartphones, tablets, MP3 players, PCs, notebooks, receivers, amps, TVs, cars, headphones — so it is a general-purpose audio extension, just a substantial one.
Who should skip it? Anyone who wants a featherweight cable for a phone in a pocket, or who only needs a meter of slack at a desk. And anyone whose headphones are plain stereo with no mic: you would be paying in bulk and weight for headset features you will never use.
Side-by-Side: Which Should You Choose?
• Best for phone or tablet with a thick case → Ugreen. The slim step-down connector fits through a case; KabelDirekt's metal-shelled plug is chunkier.
• Best for long runs across a room → KabelDirekt. 20 ft versus 10 ft is a real difference when the source is a desktop PC or a Hi-Fi rack.
• Best for light, pocketable everyday use → Ugreen. Thin, round, tangle-free, and easy to coil and store.
• Best for protecting a worn or hard-to-reach 3.5mm port → Ugreen. Its whole pitch is absorbing the plug-and-unplug wear for you.
• Best for gaming, calls and voice chat → KabelDirekt. Headset features are the point of the design.
• Best for a permanent desk or home-stereo install → KabelDirekt. The break-resistant metal shell and tight female fit suit a cable that stays put.
• Best for pure music listening on the move → Ugreen. Nothing in the design gets in the way of clean stereo playback.
I would buy the KabelDirekt cable. The reason is simple: microphone and inline-control support is the one capability you cannot work around, and Ugreen's design deliberately leaves it out. If I am extending a headset for calls, gaming or a desktop setup, I want the 20 ft of reach and the reinforced plug that KabelDirekt provides. I would only switch to Ugreen if my priority were a slim, case-friendly cable for music on a phone — and in that specific case, it is the better tool. Check the current price on Amazon before you commit, since both cables come in different lengths and versions.
No. Ugreen states clearly that it is a 3-pole TRS audio cable, so audio plays but the microphone will not work with TRRS headsets. If you need mic support, the KabelDirekt CTIA-standard cable is the one designed for it.
Yes. It passes stereo audio to any 3.5mm headphone, in-ear or over-ear. You just would not be using the headset functions the cable was built to carry.
Not inherently. KabelDirekt uses end-to-end shielding, high-purity copper and gold-plated connectors to keep the signal clean over the longer run. Length only becomes a concern with poorly shielded cables, which is not how this one is described.
Both extend the connection, but Ugreen leans into this use case specifically, framing the cable as a way to avoid repeated plugging into your device's port. Either way, a cheap extension is a cheaper thing to replace than a damaged jack.
