Caring for Your Cable

Care

Caring for Your Cable

Coil it loosely in large loops and keep it in the included leather pouch when you’re on the move.

Unplug by holding the connector, not the cable, and avoid sharp bends right at the plugs.

Wipe it with a soft, dry cloth, and keep it away from solvents and alcohol-based cleaners.

Every cable has a 1-year warranty. If anything goes wrong, contact us and we’ll take care of it.

    Great product just a little tight on ears

    Great cable with a nice sound and a quite strong design. Never the less I found that after a while my ears hurt a little maybe the top wire is a little too thick for my small ears... It is still very enjoyable thank you and the packaging is very nice :).

    Really great cable for my IE600

    Recommended. It is as good if not better than the original, sound wise. Yet far more flexible and cool looking :)
