I juts bought a clarityaloft set on Monday gone. I have to say they are excellent and half the price of bose. I bought them in New York for $512
I took them straight out and done some seaplane flying. I have never tried the bose-x so I cannot give a comparrison. All I can say is they are excellent and the difference between them and DC's is amazing.
I am in New York until Sunday so if anyone wants a set without international shipping PM me.
