Shure E500PTH Sound Isolating Earphones

The Shure E500PTH offers unparalleled acoustic accuracy. Triple Hi-Definition Drivers -- one tweeter and two woofers -- deliver precision highs and the richest lows for an auditory experience rivaled only by live performances. Encased in a low-profile ergonomic design that’s both functional and sleek, the Triple Hi-Definition Drivers deliver unparalleled acoustic accuracy that is free of outside noise. The E500PTH also comes with an industry first for sound isolating earphones, PTH. PTH allows you to activate the VoicePort(tm) microphone and adjust levels of external sound for clarity – enabling conversation without removing your earphones. Shure makes audio equipment - microphones, earphones, mixers, etc. that are used by professional musicians the world over. Shure knows sound. If your music is important to you, you want earphones engineered with the same kind of technology that your favorite divas and bands use to be sure they can hear themselves during a performance. That's Shure's "Sound Isolating" technology. Rather than introducing external elements to block out ambient sound (as noise cancelling earphones do), the Shure system creates a sealed environment that keeps noise out, without covering it up by injecting noise-cancelling artifacts that can interfere with your music. You'll hear details in your music you never heard before. The E500PTH includes an extensive premium accessories kit that offers a variety of fit and cable options that provide unmatched personal customization. The kit includes 1 pair disposable Foam Sleeves, 3 Pairs (S, M, L) of each of the reusable Flex Sleeves and Soft Flex Sleeves, 1 pair reusable Triple Flange Sleeves, 9" and 3 ft. Modular Cable Options, 1/4" adapter, volume control and zippered carrying case.
