iPlay 50 Bluetooth headphones

Hello

I have bought iPlay 50 an I have tried to connect several Bluetooth headphones that I have. Thought those headphones are working just fine with any other device I have, unfortunately none has worked fine with the iPlay 50. It’s connected instantly, but my voice isn’t heard clearly on the other side and the sound I get has a major issue in terms of clearness and sound distortion. I can’t get a single word. This is happening in phone calls and any other online meeting applications such as zoom and Microsoft Teams.

Please advise if there’s any fix can be done here?

 

Thank you in advance for your assistance
