M-Audio IE-40 High-Definition Triple-Driver Reference Earphones

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.
