I like the information on this site about the wireless headphones. I'll have to check them out myself. On the problem with low volume, I have that problem every once in a while with my detectors and what I found out is that there are times that the plug inside the detector get some type of dirt on the contacts. What I tried, and it works for me, is to put a little saliva on the jack and plug it back in. I even clean the plug a little with a small piece scotch brite pad.
