Hi, I'm selling one Goldring DR150 that I bought a while ago. It's in mint condition, and has been used for less than 30 hours. It has a balanced and detailed sound. I think this is certainly the best choice at $100 price tag if you want an open-back can that is versatile, and balanced. It also scales incredibly well if you feed it with a good headphone amp. Here is a nice review about the DR150. http://www.head-fi.org/t/411188/sennheiser-hd650-vs-goldring-dr-150 The price includes shipping in Con US. Thanks for looking. Serious buyers only.
