If you don't value your hearing then go ahead. Active noise canceling is the only way to go. There are different models for different aircraft. Some tailored to GA piston driven and others for turbine. If you only travel a few times a year then it's not worth the investment. If you travel by air on a regular basis and you don't want hearing loss then you need some form of cancelation, active or passive. Otherwise, you must increase the volume to surpass the threshold of the ambient noise. With the exception of the front half of an MD 88, all other jets are loud. 80-90+ db ambient. I've been a pilot for almost 30 years, commercially for almost 20. I wear Bose QC 25's. I ride as a passenger on 737, 717, and A320/319 weekly. 2 hours each way ATL to EWR. I pilot a 767-300 to Europe/UK out of EWR weekly. I've used more headsets than I can remember over the years, active, passive and non. I have definite hearing loss from several years of wearing non attenuating headphones..... Just my 2c...I have not found that to be true, unless you are in the back of a 172, even then the noise cancelling aspect is going to be useless. In commercial passenger aircraft, I have not had any problems overcoming cabin ambient sound with over the ear models of quality headphones. Just my experience. I have some noise canceling Beats, I let my kids listen to music with them, I use the others.
