I love my BOSE QuietComfort® 25 Acoustic Noise Cancelling® headphones, especially on log plane flights, but they eat AAA batteries like a motherf*cker. Usually it’s because I forget to turn them off. So I got accustom to carrying a lot of AAA batteries in my laptop bag. I carried them loose in an outside pocket in my bag and they were always hard to find. Not any longer.
This holds 6 AAA batteries. It’s also orange so its easy to find in my bag.
