Agreed. Some airplanes are objectively louder than others. A220s and 737max both have astonishingly quiet cabins (haven’t been up front of either yet). Once I put my noise canceling buds in, it’s even quieter, but when I pop one out I realize just how noisy these quieter cabins still are. And I’ve heard for years the A320 fam has a quiet flight deck. Maybe quieter than this CRJ I’m about to leave behind, but good gravy it’s still noisy up there. On a 737 jump I just plug my Clarity Aloft in since it’s a great noise blocker, and wear my QC20 buds on the Airbus jumpseat.

I abhor the feeling in my ears when I pull one bud out of CA when a jumpseater wants to chat in the CRJ. I’m still mulling over my headset choice and I’m between a ProFlight, or a Telex 8 with a set of musician earplugs if I need to take one ear up off.
