I use Sony nw-ws623 and it works just perfect. All controls work in both directions, never had any connectivity issues. Although Sony says that these headphones can be paired with one device only and need to re-pair every time if device changed, in fact, it works fine with F5+ and smartphone with no re-pair needed. I just pick "connect" on F5+ or smartphone and they become connected!
I have been using these and love them.

I like the fact that they don't hit the lower part of the back of my neck.
I am using Jaybird Tarah Pro with 5+ and 9.0 software. Everything works great, no dropouts or any other problems.
Does anyone here have experience with the JBL endurance series?
