I have GalaxyNote 8, Gear S3 Watch and Level U headphones. And they all work so well together. I was in a crowded train. My phone rang but it was in my bag to keep it safe. But I had my Gear S3 so I saw who was calling me and picked the call on my watch. Since my Level U bluetooth headphones were connected with my phone as well, I was able to have a private conversation hand free. All this while my phone tucked away in my bag safely.
