Bluetooth with Moto G4

I recently purchased a Motorola Moto G4. My husband has the LG wireless headphones. I tried to pair but every time I would get a phone call the voices would come over garbled like they were under water. I thought it was the headsets due to I also fought this with my last phone LG Phenix 2, so i went and bought another pair. These are called Warrior BT2. When I finished charging them up i paired them and made a phone call, same problem. i was ok as long as i held the phone but if i even went 1 ft from the phone it would cause issues. Where i live I don't have great service so when i find service i have to leave my phone in that spot. What can I do to fix this or do I need to go purchase the higher end ear phones? my husband's was 70 dollars and i still fight this. Please help
