I bought cheap headsets to start with and binned them after a few months.
My David Clarks are now over 23 years old and have been faultless.
HM kindly let me try Lightspeed Zulus but I'll stick with my DCs. They'll last longer than me.
As for all the "useless stuff" you need for training, I still use my CRP1, ruler and protractor even though I fly a G1000 equipped aircraft now.
