First I get my brand new A7s with that tube fallen off
and yesterday I go and I grab a pair of f/x500 from craigslist that looked like the box was just opened. I didn't even bother to check if they work. I go home and as I am about to plug them in I feel something rattling inside.
Now I am wondering if the guy had the rattle and that's why he got rid of them so cheap. They play and look like new (once I glued the tube back on) and came with GORGEOUS WOOD STANDS.
