The Heiserman H-251 is an absolutely stunning 1:1 recreation of the legendary and highly coveted Telefunken ELA M 251 Vintage Tube Microphone. In development for over two years, with multiple “shoot-outs” with an original 251 owned by Dolly Parton, we have received one of the very first H-251 microphones in the world and it is phenomenal! Deep, rich tone with a silky smooth air like no other mic can achieve, the 251 sounds great on everything and everyone.
