I have a Forerunner 245 which I pair with bluetooth headphones whilst running so that I can listen to music playing via the watch. Whilst doing workouts, I get alerts and instructions via the audio (lap times, workout step goals etc). My problem is that I need the music to be quiet so that I can still hear enough ambient sound to stay safe, but I need the audio alerts to be loud enough to hear clearly, which I can't whilst my music volume is set at a safe level. Is there a way to increase the volume of the alerts without increasing the music volume?
