I have the MOTOROKR S9-HD blue tooth head phones for my Evo. For the most part they are great, but when listening to music I get a lot of dropped audio. Not so much when staying in one place, but when walking with them on. The phone is always on my hip so distance shouldn't be a problem. Also I did receive a call while listening to music and the phone call ended up going through the phones speaker vs going via the head set. I only received the one call so I don't know if this is a consistent problem. I did do a test call to my voice mail, just to make sure that they did work. Has anyone else noticed these issues. Not sure if it is with the headset or with the EVO itself.
