3.5 mm Extension Cable 4-Pole TRRS – Male to Female Headphone Lead

Description

A headphone extension cable solves one small, constant annoyance: the headphone lead that stops a foot short of where you actually sit. It plugs in at one end and gives you a socket at the other, so nothing gets unplugged and nothing hangs under tension.

What a 3.5 mm extension cable actually is

This is a true extension — a male plug at one end, a female socket at the other. That sounds obvious, but it is the most common wrong order in this category, because a male-to-male lead looks identical in a product photo. If you are joining two devices together, that is a different cable. This one lengthens a lead you already own.

The connectors are gold-plated, which is about corrosion rather than sound quality. A socket plugged and unplugged every day is where a cheap lead starts crackling first, and plating is what delays it.

The 4-pole part is the bit that matters

Look at the plug. Three black rings instead of two means four conductors — left, right, ground and microphone. That fourth one is the whole point.

Most cheap extensions are 3-pole. Plug a headset into one and the audio works perfectly, so nothing seems wrong — but the mic is silently dead. No warning, no error, and people spend an afternoon blaming the headset. A 4-pole TRRS extension carries the microphone through, which is what a gaming headset, a video meeting or a lavalier mic on a camera depends on.

If your headphones have no mic at all, this still works exactly as an ordinary headphone extension cable would. The fourth conductor simply goes unused.

If the mic still will not work

One more thing worth knowing, because it is the usual culprit and almost nobody explains it.

Four-pole plugs come in two wiring standards: CTIA and OMTP. They swap the microphone and ground positions. Nearly everything made in the last decade is CTIA — phones, laptops, consoles — but some older equipment and a few professional devices are wired the other way. Audio works either way. The mic does not. If a headset’s microphone fails through an otherwise healthy aux extension cable, mismatched standards are the first thing to check, and no cable can correct it.

Length, honestly

Four lengths: one, two, three and four metres. This carries an analogue signal, and analogue picks up interference the further it travels.

At one and two metres you will never notice. At four metres you can — particularly if the run sits alongside a power lead or drapes over a power board. That is where a faint hum comes from, and it is the cable’s neighbours rather than the cable.

The fix costs nothing: keep the run away from mains cable, and cross the two at right angles rather than laying them side by side. Choose the shortest length that comfortably reaches.

Build

Gold-plated connectors both ends, moulded housings at the plug and the socket, and a jacket flexible enough to sit under a rug or behind a desk without kinking. There is no electronics inside an extension — four conductors and a shield — so build quality is the only variable, and it is what separates a lead that lasts from one that crackles in six months.

Compatibility

An aux extension cable this size fits almost anything with a standard 3.5mm port, though not every recent phone still has one.

Compatibility

An aux extension cable this size fits almost anything with a standard 3.5mm port, though not every recent phone still has one.

Compatible with:

• Wired headphones and earbuds with a 3.5mm plug, with or without an inline mic
• Gaming headsets — including those plugged into a PlayStation or Xbox controller’s 3.5mm port
• Laptops and desktop PCs with a combined headphone/microphone jack
• Phones and tablets that still have a 3.5mm headphone port, and USB-C or Lightning dongles that add one
• Car stereos and portable speakers with a 3.5mm aux input
• Lavalier and shotgun microphones using a 3.5mm TRRS connector
• Portable audio players, mixing desks and audio interfaces with a 3.5mm output

Both 4-pole (TRRS) and 3-pole (TRS) plugs fit. A 3-pole set of headphones simply leaves the fourth conductor unused.
