All user reviews for the Sony ECM-56

Used as main recording mics in stereo pair configuration and mono spot mics early in recording studio setup circa 1984
Recorded to Teac 3440 4 track reel to reel for folk rock and classical(stereo pair above orchestra)
48volts phantom required, very low background noise, used as drum overheads (not too harsh over cymbals)

Still have them in my mic cupboard and still working and fully usable
