The Telefunken M81-WH is the wireless capsule head variant of the M81 Univeral Dynamic. The wireless capsule is sonically identical to the M81 Standard and M81-SH and has the same condenser like performance, minimal proximity effect, and superior feedback rejection one expects in TELEFUNKEN Dynamic Series microphones. 


The M81 Universal Dynamic retains articulate mid-range as the M80 Dynamic, however, the top end is pulled back a bit yielding a flatter overall frequency response.


The product features the same exact dynamic capsule, head grille, and output transformer all neatly packed within a capsule body that is ready to be mated to a Shure wireless transmitter system of choice.
