Cardas Audio Clear Headphone Extension Cable

Clear Headphone Extension Adds Reach to Any 1/4" Headphone Cable

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.

Cardas Clear Headphone Extension is Clear Headphone Cable's wire terminated 1/4" (6.35mm) male to 1/4" (6.35mm) female instead of to a headphone-specific connector, so it fits any full-size headphone cable rather than one headphone model.

Grade 1, 99.9999% Pure Oxygen-Free Copper

Cardas builds Clear Headphone Cable around a dual mono run, two completely isolated cables for left and right, the same approach used in its speaker cables. The conductors are Matched Propagation Kevlar-core Litz wire, Grade 1, 99.9999% pure oxygen-free copper with SPN clear coat, gauge sizes scaled to Golden Ratio proportions, insulated in an FEP tape-wrapped jacket.

Dual Mono Geometry With a Suspended Shield

Cardas suspends a composite shield of 42 AWG tinned copper and magnet wire away from the signal conductors, carried on oversized PTFE air-tubes, then finishes the cable in an ultra-soft extruded TPR jacket. The gauge runs 8x26.5 AWG for an outside diameter of 0.170 inches, or 4.31mm.

The Connectors, Explained

One end is a 1/4" (6.35mm) stereo male plug and the other is a 1/4" (6.35mm) stereo female jack, so this cable extends any full-size headphone cable without needing to match a specific headphone model. Cardas machines that 1/4" male plug itself, a GRQ-series connector plated rhodium over silver, backed by a Cardas lifetime warranty.

Who Is This Headphone Cable Best For?

• Your headphone cable is too short to reach comfortably from your listening chair — this extension adds length without replacing the headphone cable you already have
• Your existing headphone cable ends in a standard 1/4" plug — this extension's female jack accepts any 1/4" cable, regardless of which headphone it's built for
• You want Cardas's dual mono construction in the extension itself, not just the headphone cable — Clear Headphone Extension is the same wire as Clear Headphone Cable, just terminated differently
• You move between a desk and a listening chair with the same headphones — an extension lets you keep one headphone cable and add reach only where you need it
• 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

Does this work with any headphone, or only specific models?

Any headphone whose cable ends in a standard 1/4" (6.35mm) male plug. Since the extension itself doesn't touch the headphone-specific connector, it works regardless of which headphone that cable was built for.

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 use more than one extension in a chain?

Cardas doesn't publish guidance on chaining its own extension, but the more connections in a signal path, the more places for a loose connection to introduce noise; a single extension sized to your actual reach is the more reliable choice.

Is there a step up?

Not in the Cardas headphone extension cable we carry. Clear Headphone Extension is the top of that range. If you want to go further, call us and we will talk through the whole chain.
