Before I make this investment, I wanted to clarify two important questions: I am looking for a speaker that allows me to listen to music and my voice through a wireless headset (model: Samson Airline 77 AH7 Fitness Headset) at the same time. Is this possible here with the integrated connections without having to buy anything extra? I also wanted to ask whether the music automatically becomes a little quieter as soon as you say something into the microphone so that my voice can also be heard over the music?
