This will not be long and silly. It is exact and to the point. They work great. Extremey well built. The sound from these are not embellished ,but honest. I have used many head phones over the years, and these are pretty much great sounding phones. Nice lows but not a ghetto thumping boom and thump, clear mid range, and superb highs. One would be hard pressed to damage these things-that is how well built they are. They also fold up nice for travel, and have a detachable coiled cord which is very sturdy. If you want to spend more cash, well, I would suggest the 840's-I have a pair of them as well, but alas, they cost a tad more, however, in Shure, you get more. I had bought the 440 model and was very impressed and because of this I spent a few bucks more for the 840's. Both sets of phones are extremely confortable, and both sound best with "break in time'.
