A:Answer Hi there- The OpenRun Pro can only be used while being connected through Bluetooth. While these are not hearing aids, we do have customers who use them to assist with hearing, usually by pairing the headphones to their phone and accessing a hearing aid app like Petralex, Ear Spy, Ear Trumpet, or Hear You Now. These apps use the mic on the phone to pick up surrounding sound and transmit it through the headphones. Please reach out to our Customer Happiness Team if you have any other questions. Thanks!
