Top! Very efficient! Finally silence, no loss of sound quality

I drive an Opel Meriva B Bj 2013 and had connected directly to the AUX input, or using the Bluetooth dongle in quiet passages, even when the engine is not running, annoying whistling and Ziep / clicking noises. That has yet to enjoy music, greatly tarnished just in classical music.

I was wondering about whether I rumexperimentiere with so-called ferrite cores, but eventually but chose this mass separation filter, which was also very correct. All annoying background noises are effectively eliminated, finally SILENCE!

My fear was, as this has already been mentioned here, a loss of sound quality, but I can not confirm this, fortunately.

My conclusion, people will buy you this little "Störbeseitiger", you will not regret it! This part would have earned 10 * !!!
