I've looked at a lot of the questions/answers on this forum, about headsets and I still have a question. The misses and I have different tastes in music and so she doesn't want to listen to mine and vise versa. Now I want all the benefits of Intercom, GPS, Phone, USB (for music), but with the feature of having different music sources. Does this question make sense? I'm sure this (potential) problem has come up before, but I can't find the solution anywhere. Hopefully someone has the solution. Thank you.
