Cable

When attaching the Mini XLR cables to the HEDDphone® input, make sure to push the male connectors until you hear a click. The red marked Mini XLR plug is the right channel.

Fitting Your HEDDphone®

You can adjust the HEDDphone® by changing the position of the left and right sliders. Please make sure, that the circumaural pads fully seal your ears.

Diaphragm Crackling

The Air Motion Transformer squeezes air out of multiple Kapton® folds, allowing to move air significantly faster than any traditional dynamic, planar magnetic, or electrostatic driver.

Due to this principle, you may sometimes notice quiet crackling sounds while adjusting the HEDDphone® to your ears. This happens when air pressure is applied to the diaphragm and does not affect the driver's performance. The crackling won't appear when you have found your ideal listening position.

Amplification & Burn-In

We recommend a headphone amp or high-end stereo player with at least 200 mW of power at 420. For the best listening experience, the HEDDphone® will profit from 1000mW.

This product was tested extensively in our lab and therefore does not require a specific burn-in period.

Safety & Cleaning

• High SPL can irreparably damage your ears! Please take good care when running the HEDDphone® at high levels.
• Please keep away Ferro-magnetic (steel, iron, etc.) objects such as small screws and swarf from the drivers. The magnetic field in the driver can pull objects to the folded diaphragm. This can lead to permanent damage which is not covered by the warranty.
• Do not expose the HEDDphone® to extreme temperatures, keep it dry at all times.
• Always keep electric equipment out of the reach of children.
• Use a microfiber cloth to clean both, plastic / aluminum and synthetic leather surfaces.
• Exchanging Earpads is not a problem, reach out to us for simple instructions.
