The right driver was damaged during previous shipping. The right driver is currently using a DIY dust foam, but there is a slight noise when powered up that generally disappears after a while. Additionally, the sound pressure is 5 dB lower compared to the left. I think there should be a small dust issue.

The left unit is in good condition.

The foam inside the both ear cups have been removed due to aging and deterioration.
Both driver unit has been detached from the front panel and cleaned of black adhesive. It is currently secured using 3m tape and Blu Tack.

No ear pad and headband.
