The SL-8S solderless plug has the simplest mechanism and is very easy to assemble. It was also designed to be very small and take a minimum amount of space. The cable’s center conductor and the plug tip are connected inside of the plug to make a tight and strong connection. The distance from the cable’s center conductor to the tip of the plug is considerably shorter than other brands of plugs which results in significantly better sound quality. And as the cable is solderless, the sound quality will not be affected by solder quality. Also, the outer cover of the cable is slightly viscous so when the screw penetrates into the cover material when you assemble the cable, the screw is held in place and prevented from working loose. For the L plug, the precisely machined cap gently bends the cable into position to provide the ideal strength and durability.
