Can I use an external boom mic with headphones AND an external battery.

I have a 3.5mm 4pin boom mic and headset that works perfectly on an iPhone 6. I need to make this work with iPhone 7,8 and X's.
The iPhone does this with a 4 pin jack. Has anyone tried this with the Belkin Adaptor? I have 400 people using this, and as they convert to the newer phones, I need a solution. Any help? PLEASE !!!!
