I have a brand new pair of clear Shure SE425 -- they came from the Shure factory as an out-of-warranty paid replacement for my old E4c.
My preference is to trade them for a pair of PSB M4U1 or M4U2. Terms of the trade would be negotiated based on PSB condition & model. (I'm not looking for any other gear at the moment, so please don't propose trades besides the one I've mentioned.)
Otherwise, I would sell them straight-up for $225 shipped to Continental US (firm). Again these are brand new in box, and this price is at least $15 lower than the best you can find anywhere.
PM with any questions. Thanks!
p.s. - I haven't done much trading here, but I have 15 years of 100% positive feedback on ebay and various photography forums as well.
