Ok so Andy Sabisch, just google his name if you don't already know who he is! I assume most of you reading this do, he is arguably the best or one of the best authors in this hobby! He is also a tester for the major players in the metal detecting industry so his name attached to a review should and does of course carry weight.. Andy recently did a review on my Vance Muff headphones and he has seen what all of us who own a set have seen.. If your interested in the review I am attaching a link for you to click and go read it! Please let me know what you think in the comments section of the blog page!
