I love my Bose QuietComfort 35 Headphones. Today I realized I have had my headphones for a while, but haven’t updated them in a very long time. I was on version 1.2.9 (i believe) and now I am on version 2.5.3. Just needed to go to https://btu.bose.com to download Bose’s latest updater. The new software is actually making a [positive] difference.
