Review on 🔇 BESIGN Ground Loop Noise Isolator: Enhance Audio Quality in Your Car or Home Stereo System with 3.5mm Audio Cable by Cliff Gibs

2006 Mercedes C230 - I installed an extra connector via a Mercedes OEM cable. When you plug the phone into that aux port, the sound is great. I then plugged a $10 USB Bluetooth adapter into that aux port and the sound was awful with a lot of hissing and crackling which wasn't acceptable so I accidentally found this when looking for a new Bluetooth adapter have searched. As instructed I connected this isolator to the Aux port and then the 3.5mm MM cable from this isolator device to the bluetooth adapter and the hiss and pops completely disappeared. I've seen several reviews that after a few months it doesn't work, loses bass or breaks. Fingers crossed it continues to work as it is now, but I'll update if anything goes wrong. However, for now I am very happy.
