ShureSM4 Dual-Diaphragm Condenser Home Recording Microphone
1/6
Independent shopping perspective
The Korena take
The SM4 is a home-recording condenser microphone with a 1-inch brass dual-diaphragm capsule, cardioid pickup and a 20Hz–20kHz response. Its pattern rejects off-axis noise to keep the recorded source more isolated, while the built-in pop filter is intended to capture cleaner audio with less editing. RF shielding addresses noise from wireless devices. The stated 140dB SPL rating supports vocal and instrument sessions, including acoustic guitar, drum overheads and loud guitar amplifiers.
Strong match
Who this is for
- Recording vocals and acoustic guitars in a home setup with focused cardioid pickup.
- Using drum overheads or recording loud guitar amplifiers within the stated SPL rating.
- Recording around phones, laptops or Wi-Fi routers where RF noise is a concern.
Consider the trade-offs
When to look elsewhere
- Setups that cannot supply 48V DC phantom power.
