I am also listing this item on other sites. Therefore, it may be out of stock at the time of purchase. This is the TH610, one of the high-end TH series from Fostex. The ear pads have been replaced with Dekoni Audio hybrid ear pads (approximately 9000 yen). The original ear pads are also included as a bonus. The headband has deteriorated slightly over time, so a headband cover is attached. Other accessories are as shown in the photos.
