Well MacDEF, I dunno. The fact that there's hardly any R10s being sold used should say something about what people think about them back at home.
And oh people DO buy them regardless of price, that's for sure...Sony sells about a 100 a year, 1998 models had serial #s of I believe around 1000. They gotta be going somewhere, otherwise for what it costs to make, Sony would've discontinued making the R10s long ago.
Given their price nonetheless, I would admit it'd be a little ridiculous for me to say they're the best dynamic headphones there are or whatever. If I say that, it'd be considered a given to most because of their price.
So go stare at my sig instead.
