I am using the companion speaker for skype meetings and it works great most of the time. Occasionally, the microphone stops working and the sound becomes distorted. The only way to restore the sound is to switch off/on the companion speaker. The sound issues are not related to the skype connection quality. I am using a Mac Book Pro with OS X 10.13.4, Skype version 18.104.22.168 and the latest firmware of the companion speaker (1.1.3).
I really like this product. It would be great if you could iron out these issues with a firmware update.
