I am certainly not an audiophile, but after a couple of years of using these I am completely satisfied and they would be at the top of my list if I ever need to buy another pair of headphones. Sound seems very good, and construction is solid, if slightly unpolished. Comfort is outstanding, with Beyerdynamic's unique fuzzy ear-muffler design pillowing your ears, though they can get a little hot and damp when it's hot. The cord is lengthy with a durable connector. My computer is perfectly able to power them, but apparently you might have problems getting volume out of lower-powered sound sources like portable devices. Their MSRP isn't that bad, but you can usually find them for around half the price.
