Bose QC 35 II work exactly as you described. Yes, Previous Beats Studio bought from Apple failed to deliver such experience, hence why Apple spent some dough on custom connectivity chips, but proper headphones OEMs figure it out as well with just latest Bluetooth generation

I have the QC35 II and they are incredibly flaky with connecting to multiple devices.

I honestly think there are good batches and bad ones of the QC35s. I have gen 1 and they are rock solid with the connections, never fail. Have coworkers who would swear by theirs too, while others have similar complaints as you do.

FWIW, I love my Airpods Pro and it's insane that neither Sennheiser nor Bose could beat Apple to the punch with something that works as well as those do. That being said, my Airpods Pro aren't without issues: they seem to hate my iMac. Not even the Big Sur update could change my Airpods' aversion towards reliably connecting to it.

Concur—I have the QC35, I’ve given up with all the endless niggles of multiple device support and limited them to just the phone which is my use case 95% of the time.

Yeah, my connectivity story with these got so bad at one point I ended up with two pairs, each with a little sticker telling which is for my laptop and which is for my phone. Ironically, connectivity improved with FW updates...

QC35 II.

Tip: if I use the app to manage the connections it works flawlessly. Not sure why. Huge pain though.

[sjwright]

I use the app and "flawlessly" is a joke. The app doesn't even connect to the headphones reliably, even if they're paired and I'm listening to audio through them. Maybe 10% of the time I have to force-close the app and power cycle the headphones for the app to connect.

[jolux]

Wow, that sucks. Mine work fine with the app but are flaky without it.

I have the QC 35 II and now have them wired a USB mic to make multiple devices actually work seamlessly because it was so flakey with a few devices. AirPod Pros OTOH have been perfect between iPhone, iPad, work and personal MacBook and Apple TVs. Connected to one device and all the others are automatically paired and switch with no effort.
