VANCE MUFF HEADPHONES (BEST DEUS HEADPHONES EVER)
Vance Muff Headphones were designed by Jeremy Vance of Vance Metal Detecting. In the quest for having a wireless headphone that actually blocked ambient noise but also had a very good speaker!
We tested 27 speakers at 13 different ohmages for a total of hundreds of speakers before we finally chose one to install.. These headphones have reviewed very well in comparison to all the others... see link below..
