Review on 🎧 KRIPT Noise Filter Ground Loop Isolator: Say goodbye to Car Electrical Noise with permalloy core Transformers! 3.5mm Audio Cable Black by Major Callaham

I added a Bluetooth adapter to my car that plugs into the factory AUX input on the stereo. The adapter is powered by a 5V car charger plugged into one of the car's 12V outlets. When the music wasn't playing I heard all sorts of hissing that stopped when the music played (even between songs). This annoyed me, so I looked for a good quality ground loop isolator that would pass through the entire audio range. 1.3dB. I was curious to see if he could really take it. Spring. it does! The sound quality is as expected, excellent, no more interference! Note that my Bluetooth adapter connects to my phone using the AptX codec and I play uncompressed FLAC files. If you have an Apple phone, it can only connect via Bluetooth with a lower quality. Codecs like SBC, or if your adapter supports slightly better AAC, you have more limitations on the audio quality of the source. Apple refuses to pay license fees for the best Qualcomm (AptX, AptX HD) or Sony (LDAC) codecs, i.e. Enjoy. Again, when streaming compressed music from the internet (Spotify or similar), the quality of the source is the main limiting factor, no matter how good the Bluetooth codec is.
