I got mine in the mail today too. Ordered them 3 days ago and got them today plus the price was nice too
I was considering getting a pair of Grado 125 or Senn hd590 but got these highly recommended by a couple of the forum users and all I can say is that these are great. Yesterday I went to a local shop to check the 125 and see if I had screwed up choosing Allesandro. I like the Allesandro better and this is with almost no burn in. (i got these 4-5 hours ago). Mine came with flat pads and I have heard that the flat pads muffle the sound quite a bit but in my case they work great. Since I bought these to use them with a laptop as carry arround set I tested them with the crappy onboard sound card (realtek 650F chip). I know that the sound card sux so I didn't expect much from it (at least not until I get my echo indogo) but m1 performs were well. Really easy to drive and the sound is prestine. I do like it better than the grado 125 that I tested yesterday and the grados were burned in.
I'm really glad I asked on head-fi
Oh yeah these are also some of the most comfortable cans I have used. Very light and they stay pretty tight over my ears but do not hurt my ears at all. The flat pads do feel a lot better than the grado ones.
