Dynamic instrument microphones are well set up for capturing and amplifying loud instruments like drums, guitar amps and wind instruments. What's more, a lot of these microphones come with a clip so they can be mounted directly to an instrument.
Dynamic vs. Condenser Microphones
The technical specifications of your average dynamic microphone look a lot different than the spec sheet of a condenser microphone. For a start, the frequency response range is smaller: dynamic microphones rarely dip below 50 Hertz and hardly ever reach beyond the 18 kHz mark. They're also much less sensitive than condensers, which is exactly what makes them ideal for close-miking loud instruments.
Instrument vs. Vocal Microphones
Vocal microphones typically feature a built-in pop filter. The pop filter makes sure that popping sounds like plosive consonants (e.g. Ks and Ps) don't result in unwanted little sonic explosions. Most instrument microphones however aren't equipped with a pop filter, making them easy to spot.
