MrSpeakers Ether C Flow 1.1

When I originally purchased these Ether C Flow 1.1 headphones only 5 months ago, I was looking for a good pair of closed back headphones. However, my situation changed recently and I no longer use them very much or have much of a need for closed back headphones. Mainly I am using a near field monitor set up now. So I've decided I'd rather sell them and utilize the cash toward other audio equipment. They work great and are very lightly used. As far as closed back headphones go, these are as good as it gets. They sound great out of my Hugo 2. I originally bought a pair from Moon Audio, but there was a problem with the headband slider, so I swapped them for another pair through MrSpeakers directly. That is why the invoice from MrSpeakers only says $640 (I sent the Moon Audio invoice in with the original pair as proof of purchase). This is a new pair of Ether C Flow 1.1, NOT an upgrade of an existing pair. Everything that came with the headphones is included: case, cable (1/4), certificate of authenticity, owners manual. Let me know if you have any questions.
