They look like the old Monster Cable Powerline series. I had a pair of those back in the 80s.
But as you say, it's just plain lazy on the part of the seller and he needs to be called out on it.

Here's some speaker cables I found. $500. Doesn't say if the others in the rats nest or the nest itself is part of the deal. Doesn't say how long they are. Just the brand and the price. Oh, you want a closeup you say
How's that for service? just makes you want to run out and hire this person doesn't it. Yep, attention to detail. Perfect candidate for the DMV in ANY state. I can't wait to get these. $500 is a steal...and with all the other stuff. I wonder what he upgraded too?
