vs 104 end-address condensers
Quieter than 88% of 104 end-address condensers.
Each stripe is one end-address condenser with a published self-noise, and each bar counts them; further right means quieter. This mic is in blue.
vs 110 end-address condensers
Takes louder sound than 27% of 110 end-address condensers.
Each stripe is one end-address condenser with a published max SPL, and each bar counts them; further right means it takes louder sound. This mic is in blue.
