All true, but as far as listening to music goes, it's a pity the DT250s don't sound better - to me they make the bottom end sound like the proverbial bag of hammers. I tried the DT150s, which sound better but I didn't find nearly as comfortable over long periods, and eventually settled on a pair of DT770 Pro, which seem to me to be about perfect for comfort, and a good balance of sound quality and isolation.
