I'm getting tired of lugging a CD player and discs to meets so I'm finally going to (slowly) move from CDs to, I presume, FLAC (?). Is Exact Audio Copy the way to go or something else? I'll be using an upgraded Lenovo Thinkpad from 2010, if it matters.
For circumaural, read up on the Beyer DT150 and DT250. They have both been measured and discussed here. DT150 is ~$300, DT250 is ~$200. I think both are excellent value propositions if you want real closed headphones with decent resolution and neutrality (generally hard to do with true closed headphones). Both are pretty indestructible, which is nice for true portability. Both are true closed, which means little to no leakage, and excellent isolation. I prefer the 150, but many prefer the 250. If I am honest, the 250 looks less like a lego took a shit on your head.
