Introduction

This manual provides instructions for the beyerdynamic Screwable Headphone Adapter, M8. This adapter allows you to connect headphones with an M8 thread to audio devices requiring a 1/4 inch (6.35 mm) jack. It can also be used as a plug adapter for headphones with an M5 thread, though it will not screw in securely in that configuration.

Setup

The beyerdynamic Screwable Headphone Adapter is designed for easy attachment. To install, align the adapter's threaded end with the headphone's M8 jack. Carefully screw the adapter clockwise until it is securely fastened. Ensure a snug fit to prevent signal loss. This adapter is compatible with a wide range of beyerdynamic headphones.

For headphones with an M5 thread, this adapter can be used as a plug adapter, but it will not screw in securely. Verify your headphone's thread type for optimal fit.

Operating Instructions

Once the adapter is securely attached to your headphones, insert the 1/4 inch (6.35 mm) end of the adapter into the corresponding audio output jack of your amplifier, audio interface, or other compatible device. Ensure the connection is firm. The adapter facilitates audio transmission from your device to your headphones.

To disconnect, gently pull the adapter straight out from the audio device. Avoid twisting or pulling at an angle to prevent damage to the adapter or the device's jack.

Maintenance

To ensure the longevity and optimal performance of your adapter, keep it clean and dry. Wipe the adapter with a soft, dry cloth to remove dust or fingerprints. Avoid using harsh chemicals or abrasive materials, as these can damage the gold plating and internal components. Store the adapter in a cool, dry place when not in use, away from extreme temperatures and humidity.

Troubleshooting

Adapter does not fit securely: This adapter is primarily designed for headphones with an M8 thread. If your headphones have an M5 thread, the adapter can be used as a plug but will not screw in. Verify your headphone's thread type. Refer to the compatibility list in the Setup section for M8 compatible models.
No audio or intermittent audio: Ensure the adapter is fully inserted into both the headphone and the audio device. Check that the headphone cable itself is not damaged. Test with another audio source or headphones if possible to isolate the issue. Ensure the volume on your audio device is turned up.
