Been using a pair of Bose QC25 for a while now, and I really, really, really like them. I can not understand how I survived travelling on the subway without them. Or working in an open space office environment. Yes, you are right. This has nothing to do with Bose QC25, this has to do with the feature of noise cancelling headphones (this is my first pair). However, one thing that I really do miss, is a gyroscope.
When working, I quite often get pulled into some adhoc design meetings. When this happens, a common result is this:
My precious headphones, just lying there, still streaming sound from whatever tunes are being played, and STILL CONSUMING POWER. I know, it's all on me to not forget to turn the noise cancelling function off. But, really. That is super easy to forget.
Without knowing how much power a gyroscope would consume, I would really like to see one in there. One that I could activate when the noise cancelling feature is on. It will then monitor movement at certain intervals, so that when lying completely still for a delta period, it should stop the noise cancelling function and thereby save the battery.
Apart from that. I'm in love with them. Fits my skull and my needs in an open space office environment and travelling on the subway.
Cheers,
