When it comes to speech or vocals, the tailored frequency response of the SM58S ensures a clear and dynamic sound, with a boost in midrange presence and a slight reduction in bass, thus enhancing transparency. 

Its cardioid polar pattern primarily focuses on the front axis and greatly suppresses unwanted sound sources from the sides and rear, providing excellent protection from environmental noise. 

Additionally, the built-in windscreen and pop filter significantly reduce wind interference.

Different polar patterns adapt to different recording or live broadcasting sources. Singers naturally prefer microphones that focus on their voice and suppress as much environmental noise as possible. 

Cardioid microphones, which derive their name from their heart-shaped polar pattern and by definition favor sound sources coming from the front, are ideal for this purpose - especially because they suppress unwanted noises coming from the sides or back of the microphones, thus limiting feedback issues.
