| Working Principle | Uses a diaphragm attached to a coil of wire, moving in a magnetic field to generate an electrical signal. | Relies on capacitance; the diaphragm moves in relation to a backplate, changing capacitance and creating a signal. |
| Sensitivity | Less sensitive, making them ideal for loud sound sources without distortion. | More sensitive, capturing subtle sounds and nuances, ideal for studio recordings. |
| Durability | Very durable and can withstand rough handling, making them suitable for live performances. | More fragile, requiring careful handling, better suited for controlled environments. |
| Usage | Commonly used for live vocals and instruments, especially in loud settings. | Preferred for studio vocals, acoustic instruments, and detailed audio applications. |
| Frequency Response | Typically have a limited frequency response, often less than condenser microphones. | Wider frequency response, capturing higher frequencies more effectively. |
| Power Requirement | Do not require external power. | Require phantom power or batteries to operate. |
| Cost | Generally more affordable and budget-friendly. | Tend to be more expensive due to their complexity and quality. |
