Manufacturers want to give their customers the best possible audio experience during voice calls. However, the very nature of mobile devices means that all too often noise around the callers interferes with the conversation, reducing intelligibility and making natural conversations impossible. 

The latest generation of cVc® brings advanced audio enhancements and noise suppression to the near and far end, as well as providing packet loss and bit error concealment to deliver the best possible call quality on Bluetooth® headsets, handsets, hands-free devices, and automotive.
