  • PositiveVery comfortable to wear with glasses
  • PositiveLong battery life
  • NegativeNoisy voice recordings in noisy environments
  • NegativeNo automatic wearer detection

The EarFun OpenJump are suitable for both sporting activities and everyday office use, and were particularly comfortable for spectacle wearers when tested. Their sound is versatile and pleasantly airy, even if the bass range could do with a little more depth. However, this can be better balanced using the equaliser app. Street noise is occasionally picked up by the other person when making calls.
