I would have a short request for an owner of a bluetooth headset and an iOS device (as I don't have one at hand right now). Please connect a BT headset AND a wired headphone at the same time. Start the music player. 1. Where does the sound (music) come from? BT headset, wired headset or both? 2. Click the BT headset to activate Siri. Where does the sound (SIri) come from? BT headset, wired headset or both? Thanks in advance!
