[The InCore ZE-1000 in-ear monitor is designed for detailed listening in challenging environments. A patented 5-layer silicon seal provides -30dB of sound isolation, more than any other in-ear monitor. Two sets of Balanced Armature drivers ensure wide-range frequency response for rich, detailed playback. The kevlar-reinforced cable terminates to a gold-plated 3.5mm stereo mini plug, and a selection of adapters is included for other jacks]
