Shure SE420MPA

Shure's SE420MPA is one of the company's top-of-the-line premium earbud headsets combined with a microphone for use with a music mobile phone or iPhone. The earbuds use silicon earcups to isolate sound and reduce a significant portion of background noise, and this model uses dedicated woofer and tweeter drivers (2 drivers per earbud) to more accurately reproduce the sound of high-quality recordings.

They have a wide frequency response range and have built in crossovers that distinguish between high, low and midrange frequency sounds. The microphone reduces background noise and minimizes wind interference to enhance call clarity. Currently, Shure has discontinued production of this model.
