I bought these a month ago new from Amazon and have put over 100 hours on them, no break in needed. They are mint with all the accessories and case; I did throw away the paper box since it was nothing special. This is a very good sounding headphone, nicely made, and quite comfortable. I’m looking to purchase an amplifier, so that’s why I’m letting them go. Perfect feedback, so purchase with confidence. Shipping and PayPal extra.
