Shure 181:

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

The Beta 181 is a premier live performance microphone with Shure quality, ruggedness, and reliability. Its compact preamp attaches to four interchangeable capsules, and it has a wide dynamic range for use in high SPL environments. The side-address form allows for discreet positioning in tight performance and recording settings.
