"When nearing the end of my flight training for an ATPL, I found that I had very distinct concentration issues which led to missed calls and poor focus. I was apprehensive about investing in a new headset so close to the end of my training.
I borrowed an ANR headset from the local outfitter and found that my flying improved significantly. I was unable to borrow the headset again so instead opted to borrow a friend's Lightspeed Zulu. WoW! The sheer level of exterior attenuation enables an immense level of in-cockpit focus. Until you have experienced what the Zulu can do for you, it's hard to describe how removing background din can improve your flying, concentration and thus safety.
ATC comes across like someone talking into your ear while already in a sound-proof room in the middle of nowhere in the middle of the night! The sound contrast really is that good!"
Zulu. Change your mind.
