David Clark H10-60.
Not ANR or anything like that, good noise cancelling mic so when talking on the ICOM you dont hear as much engine noise as you would with a lesser quality mic.
Not sure of the cost...But the David Clark 13.4 (it has a fully flex boom rather than a metal slide and a 1/2 length flex boom) are good headsets and weigh...imagine this...13.4 ounces. Both good headsets and Dave Clark makes top of the line stuff.
I use the H10-60 and it hasn't let me down yet. For passengers, I also own a pair of Soft Comm (I want to say Silver Fox(its one model) but am not sure of the name, I bought them at the FBO I worked at last summer and they were $80/each at cost for a retail of a little over a hundred. they work great and I even got a few sets of "demo" Gel earseals)
