Audio Magic New SHD Duplex Quietest Duplex on the market

Introducing our New SHD Duplex. We've incorporated our SHD technology into our duplex making this duplex the most amazing duplex on the market. You will find several layers of noise have been eliminated using this duplex compared to anything you are currently using. We first dampen the housing internally, next we apply  3 layers of emi and rf reduction, then our i core slug to enhance current flow, we then apply bees wax to 4 chambers that support contacts which adds even more dampening and top it off with our Nano Streaming process which enhances all conductive material as well as reduce micro static discharge.
