Got the buttonless RS-1 in today, been listening all night. Here are some quick pics with the previous generation RS-1:
They certainly aren't bad looking phones, but I admit that in person they lose some of their "oomph" visually. They don't really strike me as bold, flagship phones, but as rather timid and quiet looking. I think this effect has as much to do with the font as the lack of button. The overall quality of the wood, however, is about the same. I thought the wood itself would appear cheaper, but it doesn't. Maybe the way its cut, but not the wood itself.
As for the sound, there is certainly nothing wrong with them. They sound fantastic, no complaints at all here. Listening all night with zero fatigue. I'll do more comparisons later.
