What size do I need?
The STD model is designed to work with most of the cases on the market. We created the XL model to accommodate battery cases like those manufactured by Mophie.
What does 4-conductor mean?
Standard 3.5mm audio jacks are 3-conductor which work great for stereo audio. In order to work with headsets featuring microphones, 4-conductor jacks were created which are backwards compatible with 3-conductor jacks. This extra conductor also allows for accessory use like play/pause/volume controls and credit card readers.
Will this work with my headset microphone and controls?
Will this work with credit card readers like Square and PayPal?
Will audio quality be affected?
All good thingsā€¦

After 16 years of zero dull moments, Susan and I have made the decision to retire and check a few more boxes on the bucket list.

RadTech will begin transitioning to a new owner/facility beginning Feb 20th. While a challenging move, we'll do our best to keep things flowing with minimal interruption. It's inevitable that some shipping delays will occur - especially for custom cut Optex Fabric and ClearCal Display Films.

We want to take this opportunity to thank all of the outstanding mentors, associates, clients and journalists who were crucial to our success. To all of you, we shall remain forever in your debt.

Warmest Regards - John & Susan
