Which bluetooth headphones did you try? I have the following two and they work perfectly.
- Plantronics Backbeat Go
- Jabra Pulse
Both worked perfectly paired with my Surface Pro as well as my Nexus 6P. I also had a Nexus 6 prior to that and it paired to that device with no issues whatsoever as well.
Plantronics seem to have simply mastered bluetooth. The backbeat pro pairs easily with everything I've tried, long enough range to leave my phone at my desk all day, connects to work + personal at the same time, and are pretty good headphones to boot.
