I like the Laylas...but the only times I listen to them is when I am on the go, in a library, or next to my sleeping wife. Given the choice of the HD800, T1, LCDX, LCD-XC, PS1000, and the Layla under ideal conditions with the ideal amp/dac pairing, the Layla is the last one I would pick of the lot. Laylas are great IEMS (yes, the best), but they just don't compete with the aforementioned open cans. It is no contest. An IEM can strive to sound like an open can, but I don't think it will ever equal the sound of an open can...even if they put 100 drivers in each earpiece.
