A:AnswerProbably. And this samsung adapter will not let you play music from your phone to your car radio. when you try there is a constant clicking noise in the background. Your best bet it using Bluetooth.
A:AnswerThis will not work with car aux. If you try it your music will come through but there will also be a constant clicking sound playing just as loudly as your music. this adapter was designed to use headphones with ur phone.
A:AnswerI am going to say, "yes". At least as far as your source material and smart phone can provide. I use higher performance open-air headphones which in my experience far outperform Bluetooth earbuds. I am pleased with the results using this adapter. I found it to be a reasonably transparent compromise for dealing with the new lack of 3.5mm jacks.
A:AnswerI chose this one specifically because its for samsung devices. I've had ZERO issues so since you have an s20, I don't expect it being an issue.
