Back at Pepcom Digital Experience, we got a good hands on with Shure’s new E Series Sound Isolating Earphones. They look like any old pair of earbuds, but oh, they’re so much more. The E500PTH has “Triple Hi-Definition Drivers,” meaning 1 tweeter and 2 woofers, and what the company is calling “Push-To-Hear Control,” which allows you to adjust the level of outside noise you hear. It utilizes the VoicePort which is essentially a microphone that lets you hear things around you while you’re enjoying the isolation of the headphones. If you’re familiar with Shure’s premium products, you already know that these are quite expensive. They’re now available at your favorite electronics store for $549.
