The Isolation Pack is a great add-on for anyone looking to increase the versatility of their X1 Series or sE2200 Series mic. The integrated quick-release mechanism at the base of the shock mount makes it easy to insert or remove a mic. No screws, no hassle, just one twist to secure or release. Made from metal (rather than delicate fabric), the pop filter can be vertically positioned to accommodate any of the above mics, or completely removed from the shock mount if desired. The Isolation Pack comes included with the X1 S Vocal Pack and X1 S Studio Bundle.
