I got the Shure 440 headphones around mid June. At the same time, I bought the Shure 840 pads, because I heard about how much better they are than the stock pads on the 440 (and, granted, they are much better). I also purchased a Cowon J3, because I cracked the screen on my old iPod Nano.
Now, I absolutely love my 440s... for the most part. What I love about them is the sound. The sound signature of them is perfect; I love it. What I hate? How uncomfortable and heavy they are. The headband presses on the top of my head and gives me headaches, because a) it's too flat and b) it (the headband itself) is too heavy.
So I want another pair of headphones that have an sound signature akin to the Shure 440, because the 440s are too uncomfortable and top-heavy. I don't want to spend over $200, and I would like to stay under $150, if it can be helped.
