Most FBOs rent headsets so you can do that until you buy one somewhere down the road. I would definitely invest in a decent headset. You might not need a Bose X or Lightspeed Zulu if you are working on your PPL. I am a commercial student and I still have my David Clark 13.4s and it works just fine so far. I would love to get a Bose X or Lightspeed sometime...I hear ANR is a whole different world.
