Can I pair Bluetooth headphones and a Bluetooth chest strap heart rate monitor at same time with Apple Watch series 2

Does anyone know if you can simultaneously pair Bluetooth headphones and Bluetooth chest strap heart rate monitor with the Apple Watch Series 2? I can't find any info about this online. I hope so, since they tout running without your phone now since it has GPS. Obviously a chest strap heart rate monitor gives you a more accurate reading. And who runs without music? If they really want to tout the new enhanced fitness capabilities of the series 2 than this is a must!
