Launch Demo (Flash)

“...A first for sound isolating earphones, the detachable Push-To-Hear Control allows you to activate the VoicePort Microphone and adjust levels of external sound for clarity ideal for brief conversations without removing your earphones. The integrated switch allows you to conveniently alternate between your music and external sound…Once you get used to it, you'll wonder how you ever lived without it.”

“...Its a welcome gadget in those situations. So is the Push To Hear (PTH) circuit. This accessory allows the user to bypass the music or movie to be able to hear someone who addresses him (say, a stewardess), and to hear his own reply...With the flick of a finger the listener can get the circuit in operation, muting the input, allowing him to hear a spoken exchange, adjusting for loudness with his attenuator if necessary, and return to his listening all without taking his in-earphones out of his ears and reinstalling them for optimum performance.” 

Shure E500PTH In-Earphones, Max Dudious, Audiophile Audition, (08/07/2006) www.audaud.com

"An innovative feature is the E500PTH's bundled Push-to-Hear module. At the flick of a switch, it silences the music from your player, while a microphone pipes the sound of the outside world into your ears. The module, which runs on a AAA battery, is bulkier than I'd like, but it's invaluable for anyone who has stood in line for coffee deciding between removing one's earphones or yelling "What?" a lot while ordering a latte."
