The disinfectant wipes are for the microphone. And the control yoke. And the oxygen mask. Think about it.
Really think the company is going to issue you an oxygen mask to carry about? Of course not. None of those things...are you going to get out your autoclave and dental pick to steralize the yoke held by the last 300 pilots, when it's your turn to handle it? I think not.
Some of us are smart enough to put both fingers in our ears. Not just one. And yes, many years of gunfire and radial engines has taken it's toll. And no, as stated before, I don't do the walk around, because the flight engineer does.
And yes, I have my own headset. As stated several times before. I have about a dozen of them. None bought by any company. Headsets are provided, and most use them. I do too. I keep my own headset as a backup.
The lightweight headsets we use have no noise attenuating value, nor is it particularly needed. One would look fairly stupid trying to wonder around outside wearing the cockpit headset, anyway.
And no, the employer isn't required to provide us with "ear defenders" on the job. Further, the regulations and policies of OSHA in the US aren't the same as what you have in the UK or elsewhere.
Might as well demand your employer issue you nomex uniforms while you're at it. You just never know.
