Could you specify where I should find "Sound & Haptics", my bose app on Iphone does not have any sound settings, iphone / macbook sound settings does not have any mentions about bose or headphones with another devices.

Thanks for replying!
The settings would be found in the iPhone's main settings. Here is a link that describes the process.
Let me know if you have any other questions!

Thanks for reaching out. Would it be possible for you to try the headphones with another mobile device for troubleshooting?

I purchased a pair of QC35 IIs a month ago and have been grappling with this issue from day one. Notifications through my Mac are normal volume, but if it's connected to my iPhone and I get a call or notification, it's deafeiningly loud (definitely max volume) and I nearly break the darn things trying to rip them off of my head. It's not a great experience to constantly be in fear of receiving a phone call on a $350 pair of headphones. It just happened to me about 15 minutes ago and my ears are still ringing.
I have tried everything suggested - alert volume at lowest level with "change with buttons" set to off, testing with a different phone, etc. I think it is definitely an issue with the Bose firmware. Upon disconnecting the headphones from my phone, I could actually see the volume in the iOS control center jump up to 100% and then back down. When I uninstalled the Bose Connect app, this stopped happening and the connect/disconnect blip was no longer excessively loud. So I can only conclude that this is something faulty with the app. However the alert volume for calls, etc. is still the same painful volume.
Has this been investigated at all by Bose software staff? Would just be nice to know, because I really don't want to send back my headphones, when there's seemingly nothing (physically) defective with them, if there is a potential fix in the works. But I need to figure out something.

I was having the same issue when using Bose Soundsport headphones and an iPhone 7 running IOS 12.1. I believe I resolved the issue by lowering the volume using the controls on the headphones during an incoming call. The volume remained at this lower level for future incoming calls. Hopefully this works for others and across devices.
