Well my son and I listened to the x7i for a week and the soundstage was just not to either of our liking. I must say we both love the s4 and the s3, which we still have, but the x7i went back to Klipsch. We have now ordered the Westone UM3X and are looking for the V-Mod Vibrato in April.
However my story with Klipsch is not over. I called returns and the girl transferred me twice, even though she was in the returns department I needed. Once she found out I ordered through the website, she gave me the data on how you do a return and bam, hung up. So I overnighted the return and now they cannot find it. It seems Shopatron handles website orders and returns and it can take a week or so to show up in the system. In subsequent calls people could not be nicer, just getting no where. My last call was Friday and the suggestion was to call back Tuesday (I was hoping for a "I'll call you on Tuesday). Since we already have a number of Klipsch gear, I guess I was hoping for more.
I still enjoy the s4, for the price it's great.
