I have an ASTRO A10 headset but I do not know where to find an aux like the one that came with it. The regular 3.5 broke off and now I can't use it. Instead of buying a new headset I thought I could just buy a new aux cable as it can detach from the headset completely but to find the proper 4 line aux that plugs into the headset itself has been a real mission. Any help?
