Most pilots already own a headset. Most also value their hearing and their health. I've seen guys with puss filled skin lesions and herpes on their face wear the company sets. The alcohol wipes won't kill everything. Also, your headset will fit very nicely inside your kit bag if you only carry the manuals you are required to carry. Only carry the manuals you are required to carry. If you hurt your back and claim injury on duty, the first thing the company will do is look at your kit bag. If you have every manual they will say you are SOL.
