Hi all,  I have a XD-V70HS which I used for the first time last Saturday and it worked perfectly, however, the LM-4 headset mic that came with the system is absolute rubbish and I shall never use it again.  I bought the XD-V70HS to replace a Beyerdynamic Opus 300 system that I have been using for a number of years without complaint but will soon become illegal here in the UK.  The Beyer system uses an Opus 54.18 headset mic, I have attached a screen shot of the pin connections.  My question is, can I use this mic, I have 2 of them, with the XD-V70HS.  If so what are the pin connections in the TA4F connector.  If it is not possible to use this headset mic, would I be able to use a Shure WH20TQG with no problems?  Are there any suggestions for a good headset mic to use?  I would like to get as close as possible to the sound of an SM58 to match the other vocal mics in the band.
