The In-Ear Monitors ET IEM3 are designed to meet and satisfy the needs of musicians and entertainers. They allow an isolation of 26 dB and return a clear sound, full-bodied and balanced, guaranteeing high dynamics typical of live concerts. The In-Ear Monitors ET IEM3 are made with 3 Balanced Armature type receivers and with a cross-over integrated passive 3-way. The crossover directs low frequencies to a bass receiver, mid frequencies to a receiver for medium frequencies, while directing the high frequencies to a dedicated treble receiver. The In-Ear Monitors ET IEM3 take care of your ears isolating you from the outside and allowing you to listen securely at a lower volume. Like other In Ear Monitors, IEM3 are compatible with wireless transmission systems and portable media devices.
