Wow, I am amazed at the level of care. I currently use a QC25, and did not update to 35 because I am not happy about the Siri/Google/Alexa integration. Still, I am definitely floored by the amount of care Bose provides on their product.
I guess my next set of headphones will still be from Bose.
I used to have the QC25 until they disappeared from my desk at work. Got the new 700 and holly cow, those are great headphones. I don’t even use the app/any integration, just regular bt headphones and they work just great: I can have up to two devices connected simultaneously and switching from one to the other is seamless. I also really like how they work both wireless and there’s a wired option as well (they even include the cable). I’m really happy with the upgrade.
I have the QC35's, and the voice assistant integration is, as expected, gimmicky and not very useful.
However, you can change the button to control noise cancellation level instead, and that's actually very useful since "high" doesn't handle wind well when I'm outside, while "low" does.
Note that integration is in the QC 35 Series II - they aren't present in the original QC 35. They of course don't sell those new anymore, but you may be able to find them on Amazon on eBay. I had both the 25 and 35, and consider the 35 a great upgrade.
