I bought these second hand and they are in excellent condition.
These are the discontinued 2nd generation model. The third generation model changed the tuning and made them (by most accounts) a bit more sterile and with brighter tonality. Most high end IEM reviewers that I have read prefer the send generation model. The only way to get one is via used sales.
These models have excellent tonal reproduction and a solid, well extended bass response.
I am located in Canada. shipping is free in Canada and adds $10 USD to US buyers. I would also consider some cash+trade deals for midrange IEMs or headphones. Stuff in the 200-400 US dollar range
