Choose product variant


The Headmic Set comes with the the brand new SL Headmic 1 condensor headworn microphone, the Bodypack transmitter, stationary receiver and everything to use or install.

The SL Headmic 1 is very sleek, robust and wheighs only 7g without the cable. The black and silver design almost disappears in the environment while still offering the best sound perfomance.

All sets also come with rechargeable accupacks with up to 15 hrs of operating time. The accupack is also USB rechargeable, the cable is in the box, the USB socket is presumably just a step away from you.

The two types of sets are either Rackmount Sets (-R version), which come with everything needed for rack mounting, or Case Sets (-C version), in a transport case – without rackmounts, if you do not want to install the receiver.
