Hello, I have been trying the Phonak 5 Audeo` Smart series and the Siemens Pure 700....deciding between these two is proving to be a challenge. I was sold on the Siemens until I started to play my guitar with it. The sound was very dead...then when I tried The smart 5 the guitar came alive. Have any of you done comparisons on these two. I am wondering about the duophone feature, and if it actually works...in the model 9 Phonak?
Any commenst are appreciated.
