Hopefully you guys can help me figure this out. I've bought several usb c to 3.5mm adapters to use with my galaxy s20 ultra. All of them provide excellent sound quality for music listening but none of them does not provide a smooth call voice for the other party. Basically when i call someone they cannot hear me clearly and i can hear them very clearly.
I have galaxy s10 with headphone jack and a earphone with mic i used all the time for calls and music which does give me excellent call and music quality.
With galaxy s20 ultra I'm using same earphone and i also video recorded my self voice with both phones to check the recording quality. Galaxy s20 ultra with usb c to 3.5mm adapter is not good.
The adapters i tested below.
Can anyone give me what to buy so I can make phone calls without the person at the other end getting annoyed.
Some of these adapters I've also tried with the laptop with usb c and recorded voice is bad quality so i don't think any issue with the phone.
I tried these adapters with another usb c phone and the laptop. Both of them provide low/bad call quality for the other party. So I'm certain it's not the issue with the phone or connector. The Samsung adapter i bought from Amazon Samsung store.
Also I've bought google usb c to 3.5mm adapter and it's taking forever to deliver, supposed to deliver yesterday but not delivered yet. Hopefully that will work. If not i really don't know what to do.
Any suggestions welcome. Thanks.
