I have and use both the Connect Clip and the Roger. I find the Connect Clip works better for a single speaker wearing the mic and the Roger has better microphones for detecting multiple speakers. But a noisy restaurant is still a problem with either one.

The Connect Clip is useful for connecting to my computer the hear the audio.

But the best technology for me is the Hearing Loop. That is an induction loop installed in our church which transmits any sound coming from our audio system directly to my hearing aids via the telecom (T-coil).
