“I have to say that Thunder Audio was great to deal with. I called and the owner took over 45 minutes discussing the various features of the headsets I was looking at. Lowest price around and shipped by fed ex with tracking number. He was so helpful. I would certainly buy from him again and have the utmost respect for his business. BTW, love the Kenwood stereo that I bought for more than $50 cheaper that ANYONE else online.
