Shure Beta 87A

Leading the field for studio-quality sound in live performance, the Beta 87A has a smooth, tailored response for warm, accurate sound. Its supercardioid design provides maximum isolation from nearby vocalists or instruments.

Smooth, tailored frequency response provides detail, accuracy, and warmth for vocals
Extremely accurate supercardioid pattern at all frequencies provides the highest gain-before-feedback
Three-stage pop filter minimizes breath pop and noise
Break-resistant stand adapter
Frequency response: 50 to 20,000 Hz
