Pure Tone has developed a high quality ¼" three pole (stereo) jack using a new patented design that improves upon and offers a more reliable connection than standard ¼" jacks. The Pure Tone design features two springs for both the tip connection, a spring for the ring, and an additional spring for the shield connection. These help to secure the plug into place and create a greater surface area connection at contact points to improve stability and signal integrity. These jacks also increase the current capability of ¼" connections.
