Mine finally came back. Thanks to Westone's CS for taking care of me. Everything you have read is true here. I like David's description:
"oh the highs, the mids and the lows, what can i say? a most beautiful blend of all the flavours, much like a well made tiramisu, with neither the coffee nor the alcohol overwhelming the other, rather, complementing each other and releasing new flavours previously hidden from plain sight. the bass, wonderfully low and full bodied, bringing new definition to the terms previously used loosely, "tight, deep, impactful yet controlled". the depth and power of the bass is truly astounding, without overwhelming any of the other frequencies."
Every note is as it should be. So true, balanced, and oh so smooth...
No regrets here in moving to custom IEM's from Senn HD650's and ER4p's...
