Bluetooth Headphones Compatibility on Venu

Hi 

I recently purchased a Garmin Venu. The main reason I chose Garmin over the competitors was the bluetooth headphones music feature while training. Now after reading a while, there is no compatibility with Bose QuietComfort 35 either my other generic training bluetooth headphones (SoundBuds Slim), but only a handpicked 9 headphones list. I don't want to buy other headphones. I am very disappointed, to the point I am considering on returning this watch. Which is the release timeline to add support to more bluetooth headphones? 

Cheers
