OK let me clarify...
There are 3 ways to have wireless audio with the Simplex+ or any of our other detectors:
1) Nokta Makro Green (or Blue) edition 2.4 GHz wireless headphones. The Green Edition is included in the Simplex+WHP packages.
2) Nokta Makro EZ Wander Wireless Module - you can connect any wired headphones with a 6.3mm (1/4'') plug to the EZ Wander, then attach EZ Wander to your collar or waist and have wireless connection with the Simplex+.
3) You can use other 2.4GHz wireless headphones that have both a transmitter and a receiver by connecting the transmitter to our headphone adapter (comes in the Simplex+ and not in the WHP package). This last one has NOT been tested on our end! However, I have read on some Facebook groups that the competitor's Z-Lynk(TM) system does work on the Simplex+ but like I said this is not something we have tested on our end.
Hope this helps..
