The Beta 181 Microphone Kit from Shure includes a Beta 181 handheld XLR preamplifier and interchangeable side-address cardioid, supercardioid, bi-directional, and omnidirectional condenser capsules. This line-up of capsules allows you to use the Beta 181 on a variety of sources ranging from drum overheads to piano to acoustic instruments and vocals.

*The TAA-compliant models are made-to-order with a typical delivery time of 2 to 4 weeks. The additional cost of producing separate model variations is reflected in higher pricing compared to standard SKUs.
