Have use a PS Engineering PMA 8000BT Blutooth enabled audio panel in a helicopter for several years with a cell phone (but only in an emergency, of course). Excellent sound quality and allows pairing of more than one device; also much flexibility as to who can hear and talk on a phone call. Pretty much flawless in my experience.There may be one issue, however. This audio panel has automatic squelch adjustment which may not work well if one flies with the doors off due to wind noise. Havent tried this so cant comment.
