This omnidirectional microphone has a natural, detailed and balanced response. Perfect for natural reproduction of acoustical instruments such as members of the bowed and plucked string-families, grand piano, brass, drum overhead, percussion, overhead choir and voice -with a minimum of colouration. The response is very smooth and flat, with fine off axis performance.

It's suitable for professional studio and PA use, with a pricetag at the hobbyist level!
The small size (about the same as a normal XLR plug) makes it easy to place, without being in the way. Its size and black colour makes it close to invisible on stage. Delivered with foam windsheild and microphone holder (clip).
During manufacturing each capsule is measured, selected and trimmed by us to close tolerances. Out of range capsules are rejected. This in combination with the internal circuitry, results in a response with a unique flatness. These are quality microphones made for demanding situations.
