I tried out a Roger On In I think the model was but it was the latest of this kind. I found it fine one on one but on a small table in a restaurant between my husband and I facing each other it picked up the conversation of the table behind me as well as my husband. I also tried it in the middle of the table with a few guests and it didn't seem to work. I returned it to the audiologist who had no experience with these accessories but maybe with some support it could have worked - when hanging around my husband's neck it was great but if he only turned his head to me when talking it wouldn't be necessary so for the $1500 or whatever it cost not worth it for me.
