I'm a first time "high end" user. I bought the W3s as a Christmas gift for myself (from someone else, ha ha) and just tried them before packing them back up until Christmas. Now, as someone who hasn't ever owned earbuds over $20, this is all of course with a grain of salt, but... This was the most incredible musical experience of my life! I would pay $300 for these, if needed, in a heartbeat! I have a pretty nice home theater setup and a pretty nice car audio setup as well, but they don't even top the sound these things put out!
Initially, I'm most impressed with the following:
1) Thumping bass from such a small device! Tight and accurate, especially for double bass in metal music.
2) Detail in the high end is pristine. The symbols crashing, the high hat tapping... As a percussionist, this is terrific!
3) The accurate sound stage... I've never been able to "see" the drumset as someone rolls down the toms, but the sound just moves from side to side so nicely. Mike Mangini + W3 = Glorious. My first song with these on was Illumination Theory by Dream Theater. What a treat that was! I have new appreciation for that song now.
All in all, I am unbelievably excited about this purchase and thank all of you for recommending them (just by your high praises of them). I'm a Westone fan for life!
