The first of two Panasonic RP-HJE headphones, the RP-HJE700’s speakers are engineered with a special ribbing on the driver cones to provide a more thorough rigidity, thereby resulting in purer sound and less resonance. In addition, the ‘limb-mounted diagraph enhances the cavity capacity to deliver a wider dynamic range.’ The RP-HJE700 also boasts a tangle-free cord, a powerful Neodymium magnet for rich sound, and a solid aluminum housing, not to mention a 6Hz-26kHz frequency response, a 106dB sensitivity, and a 16 ohms impedance. The Panasonic RP-HJE700 retails for $129.99 and comes with a 90 day limited warranty.
