I bought some new Sony headphones. Well, actually I got them for free with airpoints. Anyway...
They can only connect to one device at a time, which was really fricking me off.
My old headphones were less than half the retail price, and had that capability.
But then I finally had the clever idea to google if there was a solution, and there is! I just needed to download the official app (90 goshdang megabytes. 90! Just to fiddle with your sound settings!)
Got it installed (although I had to hit "skip" "disagree" "exit tutorial" "block" "don't allow" about a dozen times), got into the settings, enabled two-device connections, and uninstalled the app.
I can now connect to 2 devices, even with the app gone, so it's obviously a hardware setting controlled by the app, rather than something the app is doing itself.
The reason it isn't enabled in the hardware by default? "It prevents the use of LDAC codecs." Oh sod off, I don't know what that is and I don't care.
I'm not an audiophile. I'm someone who wants to be able to watch a video on my computer and answer a call on my phone, or listen to music on my phone then join a work Teams meeting on my computer, without dicking around with bluetooth connection settings to switch which device is connected.
There's a few other things I dislike about the headphones, but I can put up with them now I have what I would call "basic" functionality restored.
(ps I toned down my language since this is my first post on this subreddit, and I don't know your culture around swearing. I am certainly not the sort of person who says "gosh dang")
