The grill ball and the urethane sponge inside have been cleaned with a neutral detergent and stored in a storage case with a desiccant, along with other microphones. A microphone holder is included. The following is a copy and paste from the sales site: This is a dynamic microphone that can be used to pick up sound from any source, such as vocals, guitar, snare drums, and piano. By incorporating a large diaphragm, it achieves high resolution and clear, well-defined mid-high frequencies. It is the perfect microphone for live performances, suppressing feedback and noise. Includes a windscreen to reduce pop noise.
