...Visor-mounted unit or in-ear model? I am shopping to replace my broken bluetooth device that connects to my Windows Touchpad.

I wonder if a Bluetooth that connects to my car window visor works as good as the unit that fits directly into my ear canal.

Does this unit deliver as good quality sound, being much further away from my face?


Thanks for replying with known results.
