The gold plated connecters. Like audiophile wires connectors WOW
Worth the extra money to get gold plated connectors. Fit my DECT 25 yr old Panasonic, pricy at the time, female jack in the back multi-feature unit , like very well easy to use. I bet when people call with hard to her voices, this will sharpen the clarity. Solid product for sure and will stand long term abuse and tugging.
