Shure SM4-K

The SM4’s cardioid polar pattern provides excellent rejection of off-axis noise, minimizing unwanted sounds captured by the microphone. This makes it especially useful in environments with limited acoustic treatment, allowing you to focus clearly on the primary sound source.

Robust and Elegant Design

Constructed from metal, the Shure SM4 is built to withstand the demands of daily recording. Its solid build ensures long-lasting durability, while its sleek and discreet appearance blends seamlessly into any home studio without distracting the artist or the surroundings.
