The X1 S is a refined version of sE's best-selling X1, tuned for advanced performance in every way imaginable. When sE introduced the X1 in 2010, it redefined the potential of an affordable hand-crafted condenser microphone. With the highest dynamic range and SPL handling capabilities in its class, along with expanded features that dramatically increase its flexibility, the X1 S has been improved in every way - yet is even more affordable than the original.
