Anything that helps people communicate and get through the language barrier I am all for. I have used google translate on many occasions, it's decent but not anywhere near perfect. But this is a step in the right direction.
Pros:

• Many languages supported.
• Reasonably priced compared to other wireless headphones.
  Cons:
• Need to be a google user to use this device
• Not sure about the short battery life (5 hours seems really short)
