My needs: Listen to music, movie sound tracks etc. Make Skype and GooVeIP voice calls. I am searching for a headset that will work with the A100. I presume from the icon next to the jack that this is headphones only - no mic input through this jack -- can someone please confirm that. I would prefer a bluetooth device but if there is no mic it really doesn't matter too much if I have to deal with a wire. My Plantronics Voyager 510 will pair with the A100 but there is an error message that indicates the connection is not established. Doesn't seem to be any way to get the a100 & 510 to pair properly. What are my Bluetooth options and what suggestions does anyone have for a wired headphones or ear bud solution?
