    Most low-cost earphones are made with dynamic (moving coil) drivers that have undesirable frequency response peaks and weak highs.

    Etymotic created a dynamic driver that mimics high-end drivers by inserting a proprietary acoustic side-branch to redistribute energy, smooth the peaks and compensate for weak highs. The result is the mc series with best-in-class performance.

    Why Etymotic?
    Etymotic designs products to measure, protect and improve hearing, and enhance the listening experience of music lovers everywhere. Together, audio engineers, musicians and audiologists at Etymotic have generated over 100 patents issued and pending. Etymotic has the distinction of being the first company to develop and patent noise-isolating, high-fidelity in-ear earphones.

    Best Noise Isolation
    Etymotic's earphones have the highest noise isolation of all in-ear earphones, as measured by an independent laboratory accredited by the National Institute of Standards and Technology. Reduction of outside noise lowers the risk of listening at unsafe levels.
    35-42 dB of noise isolation when inserted properly.

    Best Sound Accuracy
    mc series earphones utilize a proprietary acoustic side branch and dampers to redistribute energy, smooth out response peaks and compensate for weak highs normally found in moving coil drivers.
    The result is tight, accurate bass and crystal clear high-frequency detail at all listening levels-unparalleled performance.

    Best Fit and Style
    The mc series offers best fit and comfort in its class style, with high-gloss, polished anodized aluminum finish. An assortment of eartips is included to ensure proper seal and comfort.
