Peace, mercy, and blessings of God be upon you. The headphones are brand new, Mashallah Tabarak Allah. Their price on AliExpress is 1000. I received them a week ago. The reason for selling is the lack of need for them. The headphones are good to excellent, and with an amplifier, their performance is much better.
