HD-668 B : Not comfortable

As the title and scores suggest, these cans are not comfortable and this is a huge deal breaker for me. And this is the reason I'm returning these.

The problem is that no matter how I adjust the wings, the plastic headband just digs into my skull. The problem seems to be that the headband is just not large enough.

Such a pity because the sound that is coming from these is pretty good. The highs are not unbearable like in the 681s, the bass is astonishing for the price, the mids are slightly recessed, which I don't like but it's not a deal breaker for me.

The stock ear pads are crap so they need to be replaced.

But what I highly recommend you do is to get the Samson SR850. Supposedly, it's made by Superlux and is a copy of the 668b. But a lot more comfortable because it has the AKG style head band and velour ear pads (at least some of them).
