Thanks for reaching out, welcome to the Community!
I'm sorry to hear of the issues you are experiencing with your earphones. I'd love to help!
Is the ANC affected on your earphones? Are the earbuds free from dirt and debris?
I look forward to hearing from you!

Thank you very much for confirming this for us.
Have you connected these headphones to another device to check to see if this provides any different result?
Also please ensure that your headphones are firmly connected to your device. Does it appear that there is any damage to the 1/8" connector?
Thank you for checking this, I am very sorry that this issue persists, this is very bizarre.
