After troubleshooting in my spare time regarding a distortion issue I was having with one of my G2 wirelesses, I learned that the female input connector to the G2 receiver was loose.
I've delved into replacing antennas on some of my G2s and they all worked out great. I found very useful information on this site as well as the JW facebook page as to replacing the antennas, BTW.
However, any tips on resoldering the 3.5 mm female connector on the G2? Or has that process proven to be too intricate that it has to be sent to Sennheiser for repair?
