Query: Great Sound, very comfortable

Got these today and without the burning in period, I can notice a vast improved difference in the sound. Can hear what I've been missing with those lousy earbuds. It also tends to bring out the weaknesses in the player as well. I have a first generation iPod touch and a rockboxed Sansa e250. The Sansa sounds great and the iPod sounds muddy. Also, I think that they are comfortable and they are adjustable. Can't beat it for under $22 shipped.
