I have the Pixel Buds Pro and they kinda do that, but yeah not very well. I have them paired to my phone and my laptop, and sometimes randomly they’ll silently disconnect from my laptop and permanently pause whatever I was watching if my phone plays a notification. I can’t fix it until I disconnect from and reconnect to my laptop multiple times.
One time I was watching a video on my laptop and they randomly connected to my desktop! I hadn’t used them on my desktop in at least a year, until then!
All in all, they can flow seamlessly, but it’s 60/40 on if it works properly
At least the noise cancelling and passthrough are fun to mess with
How many devices do you switch between? For me, it’s phone, tablet, two laptops and my watch. I think that the Pixel Buds can switch between two without needing a re-pair. Meanwhile, I can stream my Apple TV audio to my AirPods as they’re also an audio source! Even if Google released basic support for this today, they still wouldn’t be able to fully catch up because they have no truly realized desktop/laptop OS so I’d live in a mixed ecosystem.
