You don't really mention why? Why are they better than wireless earbuds by Sennheiser, Amazon, Google etc?
So that's a 1 in 1 failure rate ;)
Switching devices is the only situation that I find annoying since I need to open up the bluetooth menu and tell it to connect.
That said I wish these things didn't have a microphone. People tend to shout into them.
Haven't been my experience. They sound excellent for voice stuff (paired to the Mac/iPhone)
