Introduction

Sennheiser's new line of in-ears is dubbed the IE-line. It consists of three all new models based around a dynamic driver. Today we will be taking a closer look at the Sennheiser IE7 which is the second most expensive earphone in Sennheiser's current lineup. This model uses a dynamic driver, but according to the specification list it has a slightly better frequency response than that used in the IE6s. This model is approximately $90 more expensive (or 42%) than its smaller brother the IE6. The shape of the IE7 resembles that of the IE6s to some extent, they are both made to sit flush with your ear and they both carry a dynamic driver which demands vent along the backside of the in-ear.
