gateon: I spoke with Kyle Harris (Westone Tech) and he said that you would have to go to your audiologist have impressions done and then send in the customs with your impressions. Essentially they would be swapping the electronics into a new casing. As far as cost, your audiologist would determine that... I can't imagine getting impressions would be that terribly expensive. Mine waived the fee when I had it done. I also heard of Unique Melody doing recase work for $90 or so dollars. I personally would use Westone.
LeonWho: I am looking for $450.00 (shipped). Considering these are $950 new, even with new impressions it'll be below the new price.
They're great IEMs, and the ONLY reason I am selling them is because I need to do work on my car and I haven't used them in about a year (probably 6 times total).. family life demands that I'm able to hear what's going on in house..

Thanks!
