It's not that noisy with low indicated airspeed at at high flight levels.
The clip on tie is a safety issue. Become an FFDO and you'll never wear a real tie again. Either that or you weren't listening.
I'm not suggesting a Bose. That's a decade old design and ridiculously expensive.
Ambient wind and engine noise will degrade your hearing. Just because we cruise between .74-.76 doesn't mean you can hear a pin drop in there.
The clip on tie is not a safety issue. It's a living in fear issue and most were wearing them long before the thought of being choked was ever planted. Kind of like wearing a bullet proof vest in the flight deck. You can never be too safe, right!? ;-)
