Sennheiser DW-4-US C SL Lavalier Set with Case

The set includes the bodypack transmitter, stationary receiver and everything to use or install. It comes with the MKE 1 condenser lavalier microphone - so not just A lavalier microphone, but the best and most unobtrusive one for great presentations with best speech clarity. All sets also come with rechargeable accupacks with up to 15 hours 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.
