Yeah, I wrote an in-depth review of the Sonic Enchant 100 a few years ago that you can find in this link Sonic Enchant 100: Understanding the Enchant technologies, and subsequently, a review - #27 by mstrmac.
However, since then, it looks like Sonic has come out with a new model line called the Radiant that is based on its newest platform called the Extend Platform. So it’s probably more appropriate to compare the new Oticon More (based on the new Polaris platform) against the Sonic Radiant (based on the new Extend platform). I haven’t seen anybody posting any review of the Sonic Radiant on this forum yet.
The Oticon OPN and OPN S are older generations based on the Velox and Velox S platforms, respectively, and they should be compared against the Sonic Enchant based on the SoundDNA platform, because they all came out at around roughly the same time period.
There are 2 other Sonic model lines also based on the SoundDNA platform, called the Captivate and the Trek models. The Trek is the “power” version geared toward extreme hearing loss. I’m don’t know much about the Captivate model line, but it seems like they’re the rechargeable version of the Enchant line, except they are only available in the RIC style and not available in the ITE style.
