Grado 12 Foot 6.3mm Headphone Extension Cable 12 Conductor

Grado's 12-Conductor Extension Cable Adds 12 Feet of Reach

A headphone cable must physically match both ends of the chain: the connector on your headphones and the connector on your amplifier or DAC. Getting either wrong means the cable simply will not plug in, which is why the fit matters as much as the build quality.

Grado's 12-Conductor Extension Cable adds 12 feet of reach between your headphones and your amplifier, built from the same high-quality super-annealed copper wire used in Grado's own X-Series headphone cables, with braided sheathing.

Twelve Conductors of Super-Annealed Copper

Grado builds this extension with twelve individual conductors, all the same high-quality super-annealed copper wire used in its own X-Series headphone cables, with braided sheathing over the whole bundle for durability.

No Degradation of Sonic Quality, Grado Says, With Its Own Headphones

Grado guarantees no degradation of sonic quality with Grado headphones while using this extension cable. For longer runs, Grado says the cable may be piggybacked up to 3 cables together.

The Connectors, Explained

This cable terminates in a 1/4" (6.35mm) plug at one end and a 1/4" (6.35mm) jack at the other end, extending any headphone cable that already ends in a standard 1/4" plug.

Who Is This Headphone Cable Best For?

• Your headphone cable is too short to reach comfortably from your listening position — this 12-foot extension adds substantial reach without replacing your existing cable
• You own Grado headphones — Grado guarantees no degradation of sonic quality with its own headphones on this extension
• You want more conductors than Grado's standard 4-conductor extension — this version uses twelve conductors instead of four
• You need more than 12 feet of total reach — Grado says up to 3 of its extension cables can be piggybacked together for longer runs
• Your headphone cable ends in something other than a 1/4" plug — check the connector on your existing cable before ordering; this extension only accepts a 1/4" male plug

How Does It Connect to Your System?

Plug your existing headphone cable's 1/4" male plug into this extension's female jack, and the extension's own 1/4" male plug into the headphone output on your amplifier or DAC.

Then power up the system as usual. Other and longer lengths available. Call for prices.

Pairs Well With

A headphone cable is one link between your headphones and an amplifier or DAC. It usually joins these categories.

• Headphone Amplifiers — the amp end of this cable plugs directly into one
• Headphones — the cable only helps once it's matched to the right pair
• Digital-to-Analog Converters — many desktop DACs include a headphone output this cable can feed
• Headphone Accessories — stands, cases and other gear for the same headphone this cable serves

Frequently Asked Questions

What's the difference between this and Grado's 4-conductor extension?

This version uses twelve conductors instead of four, at a longer 12-foot length instead of 15 feet. Grado's own construction language, super-annealed copper with braided sheathing, is otherwise the same across both.

What happens if I order the wrong connector for my headphones?

It simply won't plug in. Headphone connectors aren't interchangeable the way many amplifier connectors are, so check your headphones' own connector, and the amp-end plug your amplifier or DAC uses, before ordering.

Can I chain more than one of these together?

Yes. Grado says the cable may be piggybacked up to 3 cables for longer total runs.

Is there a step up?

Not in the Grado headphone extension line we carry. The 12-foot 12-Conductor cable is the top of that range. If you want to go further, call us and we will talk through the whole chain.
