In our corners, Effect Audio doesn’t need an introduction anymore. The boutique cable manufacturer has been around for about ten years now and ever since then they have been gaining popularity on a global scale.

Effect Audio is among the most popular cable brands out there, and many enthusiasts trust their products. It’s no surprise that even industry players such as Empire Ears, Jomo Audio or Vision Ears bundle their monitors with Effect Audio cables.

The Ares II is one of their most successful cables, but when it comes to corner stone products, I think the one that has been the most important to Effect Audio is the original Leonidas cable. This one put Effect Audio on the map of all audiophiles.

The Effect Audio ConX system simply allows you to swap the top-end connector of your choosing onto your cable, providing maximum versatility for your favorite cables. No longer do you have to choose which iems to buy a cable for, and which not.

It’s a simple yet effective system and as it’s selling for only $50 USD, it’s basically a no brainer when buying an Effect audio cable.

“Through rigorous testing, we sourced the best materials to ensure the connector’s resistance is kept at a minimum. As a result, the performance of the ConX connectors is on par, if not exceeding those of most connectors on the market today when it comes to sound quality – just as you have come to expect from Effect Audio.”

This ConX system initially is available for 2-pin, MMCX, A2DC, and Pentaconn Ear connectors. More connectors are rumored to follow.

Instead of describing everything in written, we decided to record a video for you. In this video we will unbox the Effect Audio Leonidas II cable which came equipped with the ConX system. Of course we then go into more detail about ConX itself.


If you have a series of Effect Audio IEM cables or if you’re planning to buy one, I fully recommend to spend the additional $50 USD on the ConX system, to make your cable more versatile. It’s a small price to pay to be able to use your fav IEM cable with IEMs with different connectors.

Now if only all cable makers offered the same type of system. Hint hint. And yes, we do know about Tomy Audiophile. I’m glad both companies have worked it out so I can love my Leonidas II cable even more.
