My advise?
Hang in there.....stick to your guns....don't cave, man!
If you are able to wait it out, they will sell...eventually.
Your price is already excellent. I sold my Heron "i" in the spring for $2300. It took 4 months, but they sold. Your pair of BH2 are one model higher, one generation newer, and upgraded as well! Easily worth $700 more!
Good luck!
