At the moment we receive many requests about
disinfection of our microphones.

If you happen to have a waterproof version you can just spray it with disinfection stuff, wipe it dry and for the cable put disinfection stuff on a towel and go all the way through the cable, best do it several times and do not forget the connector.
If you do not have a waterproof version, you will need to put some disinfection stuff on a towel and clean the microphone and then again go all the way through the cable several times.
The same thing counts for the headworns.

For the earpieces it depends if you have a version where you cannot take off the tube you have to wipe it all the way through with a towel and disinfection stuff. In case you have a Voice Technologies VT600D you can take off the tube and clean it very easily and the part with the loudspeaker you have to take care with a towel and put disinfection stuff on a towel and clean the loudspeaker, cable and connector carefully.
