, it simply works, great sound quality and the included ground loop filter helps a lot.

The Loop Noise Isolator is definitely worth getting if you ever don't have the music bumbing in your car

No ground loop buzzing noises

I didn't find difference in call quality making calls with and without ground loop noise isolator.

In my case the Ground Loop Noise Isolator was a necessity and it did well at cancelling out the constant buzzing noise.

Bought this because one of the reoccurring complaints with many BT car kits in the Amazon and Youtube reviews is the noise that comes from the car motor and the need for a ground loop isolator

The loop noise isolator works well

I found I didn't need to use the Ground Loop Noise Isolator unit - the audio was clean without it in my case

The fact that a ground loop isolator was included is the reason I went with this kit.

If the manufacturer can make one with a solid L-shaped connector it would be perfect.
