Eliminate the weak link in your chain with the new QiJack.   The secret is the Patent Pending rings which expand into an oval shape to give you consistent grip on your plug to reduce contact resistance for the best sound.   You now have two contact points for the Tip (+) and Sleeve (-) for better performance.  You wouldn’t put bicycle tires on a Ferrari and you don’t want any other JACK between you and your music.


The QiJack grips the plug tightly so is it best used on solid built products.  Thin wood walls that are not reinforced are not recommended.    The QiJack even works on Gibsons with printed circuit boards as can be seen in the picture below.

You can see in the picture below how to solder the QiJack.   The black wire is going to the sleeve (-).
