Pros and cons
Audio-Technica BP40
Pros
- Hypercardioid pattern provides exceptional off-axis rejection
- Large diaphragm dynamics capture more detail than small-capsule alternatives
- Internal mechanical shock isolation reduces stand vibration
- No phantom power required
Cons
- Hypercardioid sweet spot is narrow - off-axis coloration is significant
- Heavy at 632 g - requires a sturdy boom arm
- Needs a quality preamp with adequate gain for dynamic mic levels
Shure SM57
Pros
- Versatile - voice and instruments equally well
- Same legendary build quality and warranty as the SM58
- Outstanding off-axis rejection in loud environments
- No phantom power, runs on anything
Cons
- Flat grille means plosives hit harder - pop filter is more important
- Slightly less presence boost for vocals compared to SM58
- Frequency ceiling at 15 kHz limits high-end air on bright voices
The verdict
Choose Audio-Technica BP40 if
Broadcast and radio-style podcasters who want the noise rejection of a dynamic with more diaphragm surface than a standard moving coil.
The BP40 is unusual - it gives you the noise rejection and simplicity of a dynamic microphone with a capsule size closer to a studio condenser. The hypercardioid pattern is tighter than the SM7B's supercardioid, which is a serious advantage…
Choose Shure SM57 if
Podcasters who also record instruments and want one mic that does both jobs.
The SM57 is technically an instrument mic, but its tight polar pattern and rejection characteristics make it a solid podcasting mic for anyone who treats it right. The flat grille means you have to work it closer than the SM58,…
