Hi Cialatio and xbulder
That’s the real question, right? I’ve read a little about the channel free design reducing spectral distortion so your brain can more easily differentiate sound sources (different speakers) in a noisy environment. The theory and technical descriptions seem to make sense, and they have test results to back up the research. The Resound Azure uses asymmetric microphone settings (omni in one ear and directional in the other), and the Warp processor, and they have research showing that these features help you hear better. Everyone has their own proprietary approach, which are “revolutionary” and “the best”. I thought the channel free design sounded really good, but I noticed that none of their follow-on instruments used it. Obviously, it wasn’t popular (didn’t work well?).
I agree with xbulder - can we hear from some dispensers and users of the Symbio and Swiss Ear models? How do you like them? Thanks.
