- Brand: Audeze - Model Name: iSINE 20 Purchased new in August. Used for approximately 30 hours. In very good condition. The carrying case has not been used, but the leather part has cracked due to aging. All accessories included. Especially the Lightning cable with built-in DAC, which allows direct connection, is very powerful and has high resolution. It's rare to find a clean unit like this anymore, so please consider it.
