Subject: Defective headphones
Content: I bought a "Yobola Wireless Headphones, Bluetooth 5.1 HiFi Stereo, with Touch Control, Built-in Microphone" on Amazon in April.Just a month later the left earphone began to lose volume.Today I can't hear anything through the left earphone.And when I wear them on a call, my voice sounds breathy and I have to take them off and talk on the phone.I already reviewed the instructions and followed the instructions to unsync with the phone and re-sync them. But they still don't work correctly.Could you replace or refund, please?
