How does the sound on the 681 evos compare to the 668b? I just ordered a 668b, but it hasn't shipped yet so I might change it. I was looking for neutral, analytic headphones with good soundstage.
To some of the people looking for alternative choices for the earpads, I found
this through google with someone using DT990 pads on his 668b, looked them up on ebay and came across some black velour ones for $15, they look exactly like the AKG 240 pads (and are half the price). I'll probably stick with the 668b order and pick up a pair of those earpads unless someone here informs me that the evos are a better choice for me.
Here is the ebay link.
Edit: Went ahead and ordered the ear pads, might be awhile until I get them but I'll post back when I do to confirm if these fit or not.
Edit 2: Alright, just got the ear pads in. They're slightly smaller than the stock pads, about 1cm, but they fit. The flaps are stretchy enough but the outer edge has stitching on it which makes fitting them a little difficult. It ends up being about 3mm around the cup that the ear pads don't fully cover, but they're still big enough that they fit comfortably over my ears. If anything they feel more snug. Sound seems the same to me, the only downside imo is that they don't look as "factory" as the AKG pads might look, due to the size difference.
I did cause a tear on the flap of one of the pads, but it didn't affect the strength of it and it was more because of me fumbling around trying to fit it. Eventually I figured out if I sort of palm the earcup and use my fingers to hold down the flaps as I brought them over it was easy enough to fit them so the 2nd earpad was a breeze.
