I paired them with my watch (Garmin Fenix 5 Plus) and they worked really well. In general, I've had poor experiences with using Bluetooth headsets with my watch but the BFP probably has a much newer version of Bluetooth. With my old Jaybirds X3s, it would be difficult to pair with the watch and I'd get constant dropouts. The Beats Fit Pro pairs within two seconds and only has very short dropouts (on the order of a fraction of a second), when I rest my arms at my sides. My guess is that it has trouble getting to the one opposite my body. It's not a problem while running. This makes it a lot easier to run without my phone. Sometimes I want to have my phone with me for security but it's not that much of a factor running around my neighborhood.
