Shures E500 Earphones

Shure was showing off its flagship earphones at Macworld last week, and we got the lowdown on all of the new features: Triple high-definition drivers (one tweeter and two woofers), PTH (Push-to-Hear) Control Switch, which lets you mute your music and activate a microphone so you can hear external sound and what
s going on around you without removing the earphones, a new over-ear design which ensures comfort during extended wear, and outside noise is blocked up to 37dB. The new E500 earphones are slated to ship in May for $499 and the PTH Control Switch will be available for purchase alone for $59 and is compatible with all Shure E Series models.
