Cell phone clarity was never good as it was and bluetooth won't help here. My advice is to get a wired headset.
I am (very) senior citizen and living in India. I am hard of hearing and I do not clearly hear conversations on cell phone particularly from my son in USA. he has gifted me a bluetooth headphone. I have paired with the cell phone. But there is some problem in using this bluetooth headphone for talking on cell phone. I am able to hear his talk clearly but he says that my talk is not clear (according to him my voice is not clear,as if microphone is far away) .The headphone has microphone. while talking I also keep my cell phone near my mouth still he has problem. I do not know why. Either mic in headphone is not effective but my cell phone is near my mouth. does it mean either mic in headphone deactivates mic in cell phone or there is clash between mic of phone and of headphone. I would like to have views from more computer, bluetooth and cell phone aficionados particularly some advice.
