RadTech ProCable – Audio Extension Cable 3.5mm Male – Female

Since we looked at RadTech’s adapter last July, the company has replaced that model with a new version that comes in two lengths. Although RadTech classifies these lengths as 3 and 4 inches, my measurements–from the beginning of the plug cover on the male end to the juncture between the cable and the female adapter–were 3 and 4.5 inches, respectively. The cable is fairly thin and flexible, although the female adapter is just slightly smaller than the one used on the Helium Digital adapter, also reviewed here (see link, below).–Dan Frakes
