E Series Vs. Regular Headphones

Shure Sound Isolating Earphones deliver accurate sound compared to larger, more expensive home listening headphones and they are easier to carry. The sound isolating technology block background noise, revealing extraordinary detail and allows the listener to listen at lower levels for longer periods of time.

E Series Vs. Noise Cancellation Devices

Typical active noise canceling headphones may introduce unwanted audio artifacts in your sound. Furthermore, active noise-canceling
products are typically only effective at low frequencies. Shure Sound Isolating Earphones help to stop the noise from even entering the listening space, and do not need any extra batteries or an external body pack to operate.

E Series Vs. Other Sound Isolating Products

Shure Sound Isolating Earphones provide studio quality sound, offer a unique, more secure around-theear, behind-the-back out-of-the way cable design ideal for active lifestyles. They also provide a personalized fit kit with more sleeve options for a secure fit, resulting in better isolation.
