The IE-40 Earphones from M-Audio use Ultimate Ears technology to provide high-definition, reference-quality audio. Triple precision armatures for high, mid, and low frequencies maximize the sound field and give accurate reproduction, as well as more clarity and greater headroom typically found only in more expensive models. The patented dual-bore design provides a wide sound stage through separate canals for high and low frequencies, creating a natural mix in your ear.
The IE-40 offers a wide frequency range, allowing you to hear the deepest bass and clearest treble from any genre of music. The included universal fit kit ensures proper fit and comfort for any user, as well as maximized noise isolation, up to 26dB. The cable is designed to go behind your ears for added stability and a discrete look. A flexible attenuator/limiter is included, allowing you to reduce the signal from high-volume sources, such as an airplane sound system.
