Audix OM mics are known for being extremely efficient in reducing feedback issues on stage, and the OM5 is at the top of the line from this point of view, on par with the more expensive OM7. To obtain the best results, it's not a secret that you have to be right "on" the mic, with your lips close or touching the grille. There is little proximity effect, so no bass boominess even singing very close to the capsule. The OM5 has also the characteristic bass roll-off below 120Hz, but it doesn't mean that the mic sounds thin: it just takes out mudding frequencies you'd cut anyway, and makes the vocal sound clear and smooth. Construction is solid, and the finish looks sleek. The price seems just right, for a professional quality mic built in the US.
