Just for you to know:

With the latest firmware 2.7.1 for Sena 50S my microphone did not work.

I tried different apps, smartphones and mics included with the Sena.

To solve this, I downgraded the software to 2.6-build3 and now it is working again. 

Thank you Joe Gaebel.

 

Pls fix your firmware, Sena.

  Where can you obtain the 2.6 build or .img file? I have the same issue with Smart HJC 50B

  So, you need to download the specific version of 2.6 for your unit and variant of hardware. This is available from the sena website; do some google search and you will get there.

  The real problem is that their software for managing firmware only allows you to move forward, not backward. WTH!

  Dang. This doesn't need to be this hard.
