This sale is for a set of two Pure Tone output jacks.
The patented Pure Tone jack contains dual tension grounds and dual positive tips for optimal signal and lowest possible noise. 100% greater surface area at all contact points creates a more stable connection; as a result, high and low frequencies are greatly improved creating a much more balanced sound while eliminating frequency spikes. No more noise crackle caused by pressure grounds!
The Pure Tone jack has a tensioned design and locks the cable securely in place while the increased metal mass carries more signal.
