Key Features:
 
Evolved from personal monitor technology road-tested by pro musicians and fine-tuned by Shure engineers, the 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.

Included sound isolating sleeves block over 90 percent of ambient noise. Combined with a low-profile ergonomic design and modular cable options, interruptions from the outside world are minimized—so you can focus on your passion. And on occasions when you must tear yourself away from the music, the included Push-To-Hear Control activates a VoicePort(TM) microphone, allowing conversation without removing your earphones. Designed for the audiophile, E500PTH earphones are ideal for a premium listening experience either at home or on the go.

Triple Hi-Definition Drivers

Optimized for listening to high-quality recordings, as well as lossless formats, the E500PTH utilizes three hi-definition mini-speakers—one tweeter and two woofers. Additionally, integrated passive crossovers ensure that high and low frequencies remain distinct and defined. The result is an incredibly wide and detailed soundstage, distinguished by precision highs and tight low end. This innovative triple driver configuration is first in class for universal fit sound-isolating earphones.

Push-To-Hear Control

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 switch allows you to conveniently alternate between your music and your connection to the outside world.

   
Similar to the microphones used in Shure QuietSpot® cellular headsets, the VoicePort microphone is tuned to pick up the human voice for maximum intelligibility. Included with the E500 and available as an optional accessory for all Shure E Series models, the PTH control switch is also compatible with other brands of earphones.

Sound Isolating Sleeves

The role of the included sound isolating sleeves is twofold: blocking ambient noise and ensuring customized fit and comfort. Because every ear is different, the Premium Accessories Kit includes three sizes (S, M, L) of the Flex and Clear Flex Sleeves as well as one universal-fit pair of Foam and Triple Flange Sleeves. Experiment with the size and style that creates the best fit for you—a good seal is key to optimizing sound isolation and bass response as well as maximizing comfort during extended wear.

Modular Cable Options

Based on extensive user feedback, Shure engineers developed a detachable cable solution to enable unmatched personal customization. Two cables—9-inch and 3-foot—are included, allowing you to tailor your experience depending on activity and application.

"The makers of Shure have basically upped the ante within the market of headphones and sound gear...after I customized them to my ear canal, I heard nothing else at all. Not even the screaming neighbor's kids."

"And unlike noise-canceling headphones that add frequencies to neutralize background noise, the E Series uses a 'Fit Kit' -- soft, flexible pleasure nubs that conform to your inner ear -- to block out external noise and allow you to hear more detail at lower volumes. And, ooh, what detail you'll hear. Solid, gut-punching bass and crisp, ear-piercing highs, even in the lower-end unit. Yes, they're expensive, but think of all the money you saved with Kazaa!"
