So I received my pair of RS2i's today and after listening to them for a few hours am impressed. After switching back and forth from my HD650's to compare I now know what people mean when they talk about the laid back Sennheiser sound which sounds pretty sterile in comparison. Listening to some rock and blues CD's they can be pretty bright and sharp and more then once I found myself reaching for the volume knob to turn it down during certain songs. I have to keep in mind though these are straight out of the box so they probably need a little time to burn in.
One thing I was surprised about is I wanted to listen to them unamped to start with and plugged them straight into my Marantz CD5004 player and was kinda disappointed, I felt some energy but I guess not as much as I was expecting and the volume control on the CD player itself didn't seem like it got up that high with the Grado's. I then plugged it into my Burson amp and it was like night and day, definitely a difference for the better. I would have tried listening to my iPod with them but didn't get the adapter.
I expect to really sit down with them and burn them in a little better over the weekend but it's been pretty positive thus far. I'm still toying with the idea of returning and exchanging them for the RS1i's but that decision can come later.
