...nails it out of the park. My trusted supplier of pads and headbands nails it with these Senn HD600 pads and headband, letting me bring this old war horse set of cans to feeling new again. Ahhhhh...such a nice feeling, and SOUND. Now I'm feeling so good that I might even try some hybrid on my HD600 for kicks and giggles. Wow, scary! I highly recommend this set. When I bought my HD600 used about 4 yrs ago, the pads were well broken in, but the headband was almost flat. Sorry HD600s, and my cranium, I should be kinder to you. The new ear pads are a bit firm, and I don't know if the OG were like that. The sound is still sweet. I'm glad they're firm, though, because they should stand up to abuse for years to come. Thanks Brains guys/gals.
