Thank you for viewing. These are ear pads compatible with beyerdynamic DT990, DT880, DT770PRO, etc. This product is a third-party compatible product. I installed them once to check the sound quality, then removed and stored them, so they are not strictly new, but I think they are almost unused. Also, the foam discs that came with this product were too large, so I cut them to fit. Instant purchase is OK. I will ship via Yu-Packet Post. Thank you.
