Is the Electro-Voice RE20 worth the money, or should I buy a cheaper dynamic microphone?

The RE20 is a dynamic cardioid microphone, but that description alone won’t tell you whether it suits your voice or instrument. Compare recordings at matched playback levels if you can: louder can easily sound “better” without actually being a better fit.

For vocal duties, the Shure SM58 is a relevant alternative to audition. For instrument recording, consider the Shure SM57, listed here at £104. Neither should be treated as a like-for-like RE20 replacement; start with the job you need the microphone to do.

If you specifically want the RE20, the best-value used microphones list is worth checking before buying new. With any used microphone, ask for a working demonstration and check the connector, grille and physical condition.
