I have the QC35 and besides the noise cancelling they are crap. The bluetooth drops off when I'm sometimes only 8m away, the battery life is low, but the most annoying thing for me is the multi devices connectivity. They will connect to both my iphone and mac at the same time, but never in the way I intended to. A lot of times I need to turn off the bluetooth on the iphone, or turn the phones on and off several times, or desperately try to connect/disconnect the phones to the mac, do this a few times a day and see how it feels. There is no option on the phones to switch between devices, or even to stop multi connectivity, the phones know better and will connect to the device which is 'closest'. Good luck when you sit at the desk with the laptop and the phone on it. The only way is to use the Bose supplied app, which is full of dark UX patterns. Every time it asks me to create a Bose account, to connect my other social accounts, etc. And it doesn't even solve anything, do I really need to open my iphone and open the Bose app to turn off a connected device every time I start the headphones?
By comparison my Beats solo are much better, for range battery and connectivity, but they don't have noise cancelling.
Except that I never payed any attention to bluetooth range, it's the opposite experience here.
I have the QC35-II and never had problems, neither with battery life nor with bluetooth. In fact, given that it seems like no device ever gets bluetooth protocol right, it surprised me that the headphones do exactly what I want: connect to two devices at once (laptop and phone). So I can play music on the laptop and when someone calls, the headphones seamlessly switch to the phone, and when I hang up, they switch back to the music from the laptop. Also reconnecting works without anything to complain about. I am also switching back and forth between two locations, meaning two laptops and two phones, and the only thing that is mildly annoying is that when switching the desk, it takes a little longer to reconnect to the other set of devices again. But it does work.
What would be cool is three devices served at once (laptop, land line phone, mobile phone).
I am not using the Bose app at all.
But what is annoying is that they don't charge and work at the same time. Frankly, I was pissed when I found that out. WTF, there are integrated USB charger/voltage regulator circuits readily available that do that for you. Probably it's due to heat dissipation problems as always so they might have artifically disabled this to avoid at all cost headphones bursting into flames on people's heads.
The QC35 was the first product that made me realize Bluetooth had turned a corner. The way my calls could transition from QC to my car when I start it, back to the headphones, seamlessly, we a revelation. As was the time I walked to the bathroom without my phone, and my music kept playing, 30-40ft through tile walls.
I'm very, very happy with the BT performance of my AirPods as well.
I bought some Outdoor Chips 2.0 snow sports earpieces for my ski helmet a few years back, and they took me back to the bad old days of bluetooth; static and cutting out when you dare turn your head the wrong way or put your phone in the wrong pocket. They went back to REI, and were replaced by Sena Snowtalk which works the way that modern BT stuff (cars, Bose, Apple, etc) works.
I have the QC35-II as well. I've now disabled it on my phone, and hopefully it will only connect to the computer. I wish they would have put a physical button and let me cycle through the connected devices. But no, I don't know what they've thought, that the headphones will guess my intention? The reason I have it on my phone is that because of the poor bluetooth range I will keep the phone in my pocket and stream to the headphones when I walk through the house, but when I come back to the computer I need to hassle again to switch the connection.

This is the main reason why I have never bought a Bose product before (and probably never will). I've heard this assertion way too many times about Bose headphones, that besides noise cancelling they are average (if not worse) headphones overall and of course way too overpriced. I've switched to ear monitors and to be honest that turns out to be a good enough noise cancelling solution at least for me (provided that you get a good fit). I tend to just use wired headphones as you get rid of the potential issues that you mention: bluetooth and battery. Hope that good headphones companies keep manufacturing wired headphones in 10, 20 or 50 years time but I see that hard as laptops and phones are slowly deprecating the beloved jack connector.
Strange, I've used QC35 II so far with three different phones and one tablet, all Android, no problems whatsoever with Bluetooth. Turn on BT in the device, click the BT button on the headset to cycle the device. That's basically it.
EDIT: I turn off BT in all but one device!
I don't use the Bose app for anything. The only time was to update the firmware and re-enable the noise cancellation button, which somehow vanished.
As for range one can't expect much more with Bluetooth, especially indoors.
If you meant QC35 II and not QC35, could your issue be something in the Mac and/or iPhone and not the headphones?
