These were purchased from Massdrop this time last year, I'm the original owner.

When I got these, I gave them 300 hours to burn in, and although I thought they did, they didn't. Their sound didn't mature until my seventh month of ownership, and as a consequence, these didn't grow on me and I've used them scarcely. For the same reasons, they're in excellent condition; I've got enough Senns in my life, I can let this one go.

I’m listing them for $175 flat, Paypal fees and shipping are included.
