Hi @mrspeakers, thank you for pointing out this simple mod and how it can affect the sound signature of the A2C. I was wondering if you could also describe the intended affect of the various dampening pads that are included with the headphones. The packaging materials indicate that the black foam pads are the "least dampening" and the white felt pads are the "most dampening", but could you clarify what that means in terms of sound signature of the headphones when using each of the dampening pads? Does "most dampening" mean that there is a reduction in the higher frequencies, or the lower frequencies? Or does it mean something else altogether? Thank you!
