I use the peltor 8006.
Had it for a while now! No probs! Great headset and fairly cheap!
Good luck with all the flying!
Just a quick thought have you tried applying to the Navy or RAF for a flying scholarship to take the cost away for some of your flying?? GAPAN also do an FI one??
I got a Navy flying scholarship 20 hours PPL training with no obligation to join!!
I was invited for an interview with GAPAN for the FI rating but got a flying job instead!!
PM me if you want anymore details! Have fun!
