Article number: BETA 181/C
Availability: Ships from manufacturer
Delivery time: Normal delivery time is 2-7 business days, subject to availability.

The Shure BETA 181 is an ultra-compact, small-diaphragm side-address condenser microphone, designed for discreet placement and control in live and studio environments. Featuring interchangeable cardioid, supercardioid, omnidirectional and bidirectional capsule options for superior versatility, the small diaphragm design provides superior audio with consistent, textbook polar responses in a form factor small enough to get close to the source in the tightest conditions.


  • Interchangeable polar pattern capsules attach to a compact preamplifier with integrated XLR connections for the ultimate in low-profile application flexibility (Each Beta 181 ships with one polar pattern capsule and one XLR preamplifier. Capsules available separately for custom flexibility.)
  • Precision-engineered, compact side-address design features innovative locking ring to provide secure connection between capsule and preamplifier
  • Frequency response tailored for wide dynamic range applications for use in high SPL environments
  • Furnished with stand adapter, windscreen and carrying case (carrying case will securely protect up to four polar pattern capsules)
  • Shure Beta181/KIT version available with all 4 polar pattern capsules (Bidirectional, Omni, Cardioid, Supercardiod) and an XLR Preamp

I love this mic! Especially on toms. Also great on choirs, piano, and Leslie cabinets.
