What are sound isolating earphones?

Sound isolating earphones were originally developed as Personal Monitor Systems to allow musicians to hear their own performances in loud onstage environments.
They work by using soft, flexible sleeves to block background noise, allowing small, high-performance drivers to deliver incredibly precise sound directly to the ear. By selecting from an assortment of included soft sleeves, you are able to personalize the fit of the earphones to your ears.

What is a Dual TruAcoustic Microspeaker?

It is made up of two balanced armature drivers that serve as a dedicated tweeter and woofer. It also includes an integrated passive crossover that ensures high and low frequencies remain distinct and defined.

Why is there a modular cable?

The detachable modular cable is perfect for customising the length between your earphones and MP3 player. Need more length? Add another cable. One 3-foot cable is included. Also available as an accessory.
