I've had the Phonak Eleva with the Bi-Cross for over a year now and am really glad I got them. I ended up totally deaf on the right side from the translab, and my left side was impaired from a car accident which left me with only about half the hearing over there, so i really needed something to get back to work and just function as normal as I could again. It's true that you dont' get directional hearing back, but they add a depth and some extra clarity to what the hearing aid is picking up. You can really notice it if you put the hearing aid in first and get that level, then put on the bi-cros one and immediately notice the difference in volume and tone. During the day, I stay in the bi-cros mode all the time; the only downside being that you pick up a little extra interference from some computers, certain neon lights, and also when you walk through the security bars at the entrance of stores. Small price to pay, though, for the gain you get. I love all the modes in mine (mute, hearing aid only, bi-cros mode, t-coil mode, and bi-cros mode with the hearing aid side toned down a little bit. That one is good when you don't want mute, but what's on the left side is a little overwhelming and you want to still hear it but not quite so loud, like in the car to hear the passenger talk while toning down the road noise from the left window; also at my son's band concerts!
