Summary: Sennheiser has crafted a very successful line of in-ears with the IE-line. The IE7s are no exception, with an incredibly big sound stage and musical presentation they are a winner. My main beef with the IE7s is the sharp edge of the ear piece.
Pros: Midrange, Good amount of details, Pleasing sound signature, Musical presentation, Instrument separation, Sound stage!, Full bass with good precision and extension
Cons: Price, Will lack a bit of sparkle for some, Ergonomics for some
