I have been wearing them until 6/12/2015's digital Sumo DM BTE (still don't like its audio [echoes, autovolume lowering, whistles from specific sounds, etc.] compared to my past analog models). I have been wearing Oticon's analog models for about 35 years since I was little. I think all my hearing aids were Oticon:

Three 380P from 9/2/1999 to 11/29?/2011.
E38P and others (light brown color -- don't know their models nor do I still have them) before that.

Thank you in advance.
