Shure SE420 Sound Isolating Headphones Details

Key Features:

Evolved from personal monitor technology road-tested by pro musicians, the SE420 is precision engineered to provide a listening experience that’s true to live performance. Rediscover your music with Dual TruAcoustic MicroSpeakers that deliver an incredibly rich and detailed listening experience. Designed for listeners who are as passionate about their music as the musicians who use Shure microphones, the SE420 offers a truly revolutionary audio experience.

Sound Isolating Design
Included sound isolating sleeves block over 90 percent of ambient noise. Combined with an attractive ergonomic design and a modular cable, interruptions from the outside world are minimized, enabling you to focus on your music.

Dual TruAcoustic MicroSpeakers
Optimized for listening to high-quality recordings and lossless formats, the SE420 employs two balanced armature drivers that serve as a dedicated tweeter and woofer. Additionally, integrated passive crossovers ensure that high and low frequencies remain distinct and defined. The result is a listening experience that reveals the hidden details of your favorite music.

Premium Accessories Kit Includes:

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 Fit Kit includes three sizes (S, M, L) of the Flex and Foam Sleeves as well as one universal fit pair of 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
Based on extensive user feedback, Shure engineers have developed a detachable cable solution to enable unmatched personal customization. An included 3-foot cable allows you to tailor your experience depending on activity and application.

In addition to the sound isolating sleeves and modular cable, the premium accessories kit includes:

  • ¼” Adapter

Offers a solution for home stereos or other applications with ¼" jacks

  • Carrying Case

Provides a convenient, tangle-free solution to store your earphones

  • Level Attenuator
