I made the mistake of paying a lot of $$$ to install the WHIM and replace my wired headsets with HD sena 20s units on my CVO Roadglide 2015.
cram decision, the quality of the sound is crap, the mic sensitivity is TOO sensitive, despite making various configurations changes. The mic activates at around 30-40 mph, when this happens the radio volumes reduces and unable to hear.
I have been working with sena support, although helpful, useless at fixing faults.
If you review Sena in general, you will see that they have a design issue with ALL the products with the mic being too sensitive. Sena support response was to go to HD and get them to fix........
Trouble is, I believe this is a Sena issue and not HD, although I do wonder just how much testing HD did before authorising the switch to Sena. Clearly the test was ZERO, otherwise why would they select such a crap product???
The best I have done is to make config changes in addition adding an extra large cover on the boom mic.
