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.

I feel like I am back in high school
I might add a picture later. So, I bought a retro classic phone off of Marketplace for $25, I love it, it's silver and I wanted it, and then I got phone service through Vonage just so I can be able to use the phone, I bought a 50 foot cord just so I can walk around with the phone hanging off my ear, like in HS, MS, Elementary School. Anyway, the downside is that the box that connects to the wi-fi is downstairs, so I needed this splitter and bought cordless phones so that we can take the stairs to our room. It works perfectly, and I'm extremely happy. I have sent my new home number to friends and family so they can call me; I'm out of cell phone range.
