Sennheiser MD 421 Special Edition

Wedemark, Germany - May 5, 2010 - 2010 marks the 50th anniversary of the introduction of the Sennheiser MD 421-U large diaphragm, cardioid, dynamic microphone. The MD 421, which is still in production as the MD 421 II, has been one of Sennheiser's best-selling dynamic microphones for decades.

The MD 421 has been improved over the years with upgrades to the housing, output connector, basket and capsule assembly. A limited-production MD 421 Special Edition of the original design was introduced in 2003 to commemorate the 90th birthday of Sennheiser founder Fritz Sennheiser.
