I want to get a new pair of sony XM headphones. Right now, I have my older brother's 6 year old XM4's, and my main issues are that the noise cancellation is not perfect (I have a few siblings and pets that make enough noise to still be distracting) and that when wearing it for long periods of time, the areas right around my ears where the earcups touch my head hurt and I have to take it off for a few minutes.
I plan on studying in a dorm or library where it'll usually be pretty quiet, and will need to be able to have them on for long periods of time. I usually use my Airpods for everyday listening to music and the xm4s when studying because they have better noise cancellation, so I don't care if one is worse for daily use outside of studying. The case size does not matter for me, as my backpack is large enough where it can comfortably hold both. I also have a relatively small head, which Idk if it contributes to the discomfort.
The XM5's are currently on sale at 270 dollars while the XM6's are 450 dollars, so its a 180 dollar difference. If the XM6's dont provide 180 dollars worth of comfort and noise cancellation improvements, I would go with the XM5's. Sound quality is not a problem for me, as I can't really distinguish between audio quality past the level of my airpods pro. I also want to buy one that will last for all 4 years of college (and ideally even longer). Which would be the better choice for me?
