t-coil vs dai

[etalton]

If this thread has been posted before, I am sorry...I did search the topics and didn't find it. Found several links to t-coil, but none to dai.
I have a Widex Inteo Pro and have the boot for accesories already since I have a mic for me "deaf" side to give me some directionality. I am looking to add some accesories that I can use with my remote. I want to be able to plug into my cell phone, my mp3 player(s) and my tv so that I can hear better but not sure which is best..t-coil or DAI..any one have an opinion?

there is one link to DAI:
HearBuddy DAI Cellphone Accessory

my guess is that DAI will work better. in essence you use t-coil when you can't get wired signal between two devices.

hope this helps,
Ed

That helps a lot and kind of goes with what I had been told, but since that came from my audiologist, thought it best to ask the real experts
