Koss KDE250 - Overview
From Koss website:
Koss developed the KDE/250 with a pair of dynamic transducers that mount at a perpendicular angle. The larger 20mm transducer is low frequency dominant and ported while the 13mm transducer focuses on mid and upper frequencies in a side firing angle. This combination of transducers allows greater efficiency and accuracy across the entire musical spectrum to levels that exceed audibility. Each KDE/250 features a matching set of customized ear clips. These three clips can be adjusted for height with a special knurled knob on the element case assembly. Rotating the knurled knob dials in comfort for a perfect fit. Koss also developed a unique hinge mechanism to accommodate the intrinsic shape of the ear's tragus. This hinge plate allows the listener to modify the attack angle of the transducer as it enters the ear canal improving comfort, isolation and enhancing transparency. The KDE/250 allows listeners to enjoy a custom fit while experiencing the full scale of the musical sound stage.
