The Panasonic RP-HJX20 offers the ultimate in comfort, convenience and premium-quality sound. Featuring not one but two sets of neodymium magnets and a direct, axial sound path design, the RP-HJX20 delivers clear, highly-accurate treble and mid-tones with minimal distortion while a large, aluminum bass chamber produces bass that's deep and resonant. An improved earpiece design provides a comfortable yet secure fit that blocks ambient noise from the surrounding environment.
