The condition, both functionally and cosmetically, is nearly like new. I'd rate it a solid 9 of 10.
Use - no issues
Scratches - not really; very small if any
Functionality/performance - sweet. Everything works When I fired them up to make sure everything works I was smitten all over again, having second thoughts about selling. It just dials up the goodness both in terms of DAC and amping.
Ownership - I am original owner and bought these October 10-11, 2012 for around $170. They have had light use (I have over thirty amps and listen mostly to a smaller subset of that number).
Everything works - yes.
Accessories - mostly. The E7 comes with a band to strap to a DAP. E7 has its original box. The E9 does not have original box, and one of the two, if I remember right, does not have the little instruction guide.but these seem to be available on line. I include power cord but no other cables (don;t think it came with any?)
Hope this helps,
