Shure Beta 98H Condenser Clip-on microphone that you can clip to the bell of any wind instrument or the rim of any drum.

Premium cardioid condenser instrument microphones that clamp onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck and ratcheting swivel joint allows the mic to be easily positioned and secured, and an isolation shock-mount reduces the transmission of instrument 'key noise' and other mechanical noise. A gooseneck angle brace is included to provide better retention of the microphone placement during more active performances.
