Sennheiser Evolution Wireless Serie ew100 - This has been used a handful of times only and has been unused and in storage most of the time.  MISSING: is the SKM 100 hand held transmitter that came with the original purchase.  All other parts are included and pictured above. 

This system offers musicians, video and sound amateurs high-quality state- of-the-art FR transmission with a high level of operational reliability and ease of use.  It permits wireless transmission with studio-quality sound.  The transmission system ensures interference-free transmission and minimizes dropouts in the RF link.

• Diversity Receiver EM 100: The plug in transmitter converts a standard wired microphone into a radiomicrophone.  The receiver can be used with either telescopic antennas or remote antennas  It connects to the amplifier/mixing console using a 1/4" (6.3mm) jack  The AF signal output level can be adjusted. 
  
• EK 100: The unobtrusive clip-on microphone is virtually invisible, and its omni-directional pattern minimises droup-couts caused by the speaker turning his/her head.  It is ideal for theatre and presentation use.  Sound recording and reproducing equipment such as amplifiers, video cameras, etc. can be connected to the EK 100 receiver.
  
• ME 3 Head Microphone: This is a directional microphone, i.e., the sound inlet should always be directed towards the sound source (e.g. mouth).
