I use headphones, which cover the full ear so I don't get any "tired ears" from those. Maybe you're using a totally different model (no idea if BOSE have earphones and if they're any good - I avoid any earphones exactly because of getting "tired ears" with them).
If you're using headphones, maybe you have the QC 3 (which are widelly seen as shit)?!
I have had over the years the original QC, QC 2.5 and QC 3.5 and still use the QC and QC 3.5 with none of those problems (funnilly enough, the oldest, an original QC, uses a single removable AAA battery, and I use rechargeable ones and even that will last around 3 - 4 days, whilst the built-in LiPo in the QC 3.5 lasts even more than that when using bluetooth, and even more when using an audio wire).
