Which is better for recording rap: a dynamic or a condenser microphone?

For recording rap vocals, a condenser microphone is usually better.

• Why? Condenser mics capture more detail, clarity, and the full range of your voice—ideal for studio rap vocals.
• When to use a dynamic mic? If your room is noisy or untreated, or your style is very loud/aggressive, a dynamic mic (like the Shure SM7B) can work well because it rejects more background noise.

Summary:

Noisy room or aggressive style: A dynamic mic is a good alternative.

Studio, clear vocals: Go with a condenser mic.
