I'm currently on 11g but I've run viper on 20a also can't say anything about h. I may have during all my adventures but to tell you definitively idk. But what I posted as working for me seems to have everytime I've used it. Came remember and don't feel like looking right now but I lose bt when watching a video and a call comes through but I decline it. I keep getting a beeping sound until I Toggle bt and the earpiece reconnects
