His bad 1

This minijack converter -> K7 has a rather poor sound reproduction. I had taken to replace a former dating from 4 years whose connection was faulty and that created a distortion at a certain noise level on the MP3 (so I paid the sound of my car stereo, the price of a breath). The new converter was worse. I returned to Amazon as Article faulty. If this is the case, it happens, if the problem is widespread, this is a scam. I ordered another Hama brand, which satisfies me.
