I used the A20's in the CRJ for 4 years and they were great. Made the switch to the proflights so I could have something less bulky. The A20s definitely have better noise cancellation (especially in the lower frequency range), but for the RJ the proflight is just fine. I recommend them for guys flying jets. For anything else, I'd go with the A20.
