The besign fm radio frequency interference filter is capable of outshining several other filter featured in this list in overall features for the price point. If you've struggled with ground loop noise, this little device will be a miracle. This device is designed to eliminate buzz caused by a common ground loop. It has very little sound output and also can be very noisy. It also gets rid of the same noises when you charge your phone the same time you use the aux cable.

The receiver has a very loud high pitch whine when it is not paired to a device. If you are using the auxiliary jack on your car stereo this is a must-have. The quality is fantastic, there is zero electrical connection from one side to the other. It kind-of suppresses the noise from the car, but it also suppresses one channel.

Why We Like This:
  • Effectively gets rid of feedback loop background noise
  • Eliminates ground noise from bluetooth plug in
  • Works well to eliminate hiss in car radio
