I've daily driven the xm3's and the xm4's for years and their multi-device support is so bad that it literally makes it worse than not having it at all. I explicitly disable multi-device support for them because the headphones will randomly jump around for seemingly no reason at all making them entirely unusable. Apple's bluetooth headphones, assuming you are living exclusively inside of the apple ecosystem, are the only bluetooth headphones that have multi-device support that is actually functional.

If you chain your xm4's to a single device then they work pretty much flawlessly but that is also way less convenient.

I disable the multiconnect on my XM4s as well. They switch based on what's currently sending signal, but one has to stop broadcasting first. It disables LDAC support anyway if you use that. I was torn between the XM4s and Airpods Max but ultimately am tired of picking up more Lightning connector devices. I will no longer purchase things that don't charge via USB-C. I use my XM4s daily as well for over 1.5 years now (Jan 2021), and have to be in my top 5 things I've bought in my life that I feel were worth every dollar. I'll be buying the XM5s on launch day.

I also had a pair of Airpods Pros, they're so close to being the perfect single pair of headphones for everyone. But they hurt my ear canal with anything but the small tips, and then they wouldn't seal.

I have the XM4s also. I've also had problems with switching devices at times, notably with certain Mac apps that would stay connected (sending silent audio?) and prevent them from switching to the other device. But this seems to have been resolved with recent macOS updates (or maybe app updates?), and I haven't had the issue for a while.

In any case, any occasional pain caused by multiple device connections is vastly less than the pain of having to manually switch devices... every. single. time. I had the XM3s before, which had no multiple device support, and it was horrible!

Err, the XM5s have been out for a few months now.

Heading straight there! I wonder why no one mentions these. I’m looking forward to more of what Sony serves up with these.

Disagree. I had the XM3s before and it was a constant pain having to manually switch devices. Sure, it's not 100% perfect, but the XM4s seamlessly switching between my laptop and phone is a dream by comparison.
