Car Bluetooth Ground Loop Noise Canceller (2)
It was called China Post Registered Airmail,
It started with L, not the first R ... and it took two weeks.
I received a comparison of installation ...
It's the same.
Ground noise disappears.
Sorry for the domestic seller,
Buy it from Ali!
The disadvantages of the two products (or the disadvantages of the latter)
When I get into the main USB port on my car, he sometimes recognizes something else and says that he does not have a file, so he goes to the radio.
It plugs into cigar jack charger.
Oh, and these kind of products have only about 200mA of allowable current, so Bluetooth receivers are okay, but they will not survive if they are directly connected to DAC.
