I guess I’m easy to please, but, recently I got myself a better bluetooth dongle over the holidays. I had one before, but it was stupid cheap, connection was frail and didn’t have good range. Now I have one with Bluetooth 5.4 and I’m amazed with what I can do with it.
I can funnel sound to any one of my bluetooth speakers so I don’t have it hogging my main speakers when I want something close by me.
Speaking of which, I wish I had really known this far earlier in my days of using a computer. But, being able to split audio in multiple ways. I can assign where sound is going to, program to program. One browser gets these headsets, that browser gets the TV speakers .etc
That kind of shit amazes me and damn shame I never explored this before.


I’m not sure exactly whether this was protocol improvements or some other form of implementation improvement (antenna location?) but, yeah, I’ve found that the popular Sony WH-1000MX6 headphones have much better ability to talk to my Bluetooth transceiver at range than do a number of older earbuds and headphones I have. The range is closer to, say, a cordless phone or WiFi.
Depending upon your use case, that may not matter; for a smartphone, more range probably doesn’t matter much. But if you’re talking to a desktop computer, it can be handy.
