Bose headsets
 

I am confused abut US FAs perception of Bose Headsets...LAst week I took a PHL-LAS flight and was told by a FA I couldnt use the Bose headset while sitting upfront, as the adapter wasnt the same...I showed her the connections was better than the set supplied as it was gold plated...She became gruff and was not helpful to me the remaining duration of the trip...Whats the deal here, as in over 300 segs, this was a first.. What are the rules? Any ideas?
