Have you tried Apple's AirPods?
So I'm excited to see more wireless headphones like the Air Pods and what kind of innovation they can bring.
To be fair: I've had to re-pair them twice after they just wouldn't connect.
Once in a while only one comes on at first and it takes a few seconds for the other to 'kick in', but that's automatic.
A handful of times I've had one cut out and come back within a second or so.
But that's daily (at work) use since launch. I'm perfectly happy with them, these aren't serious issues.
If you're into higher-end headphones, I can heartily recommend the B&W P7 Wireless. Fantastic sound and the Bluetooth has been extremely stable for me. And they have a wired port as well, so if you want to go that route at any time they still have you covered.
