Have you tried this with the (optional) wind deflector?
I didn't want to spend the $400+ for one of those, at first, until I met someone that actually had one in his E93. And...I really wish I'd bought one on Day One instead of waiting 8 months.
It cuts down on the entire wind noise inside the car, plus makes the air conditioning's cooled air stay inside. And with lower wind noise, the other parties on the phone can hear much better.

When one wants a cabriolet, is there really any other choice than an M3? No. No, there's not.
