I am ready to part with my iSine 20s. They are in perfect condition, and include a bunch of extra ear tips and ear hooks (I thought I lost mine, ordered the extra set, and then found the originals). I have all three cables: analogue, cipher (v1), and the new bluetooth/DAC one. Price includes shipping CONUS, but if you live in DC and want to pick them up in person I will consider a discount.
I am also potentially open to trades, especially if you are local.
