The e604 3-Pack from Sennheiser includes three high-SPL handling (more than 160dB) cardioid microphones, optimized for use on drum sets and other percussion miking applications. Each microphone actually comes with an integrated, pivoting mount that can screw directly onto mic stands or mount on the rim of a drum, making setup very efficient. A balanced, clear, low distortion signal from the e604 is similar to a high-end studio condenser microphone. A lightweight voice coil provides extended high frequency and rapid transient response. This quality drum mic is housed in a tough, reinforced glass fiber body designed to suppress impact noise.
