Input:
I'm glad I paid a little extra for this ancient piece of technology to allow my ancient car stereo to play songs from my phone. After having a cheapo adapter that sounded like my stereo was outputting music through a sardine can, this adapter reminds me that most of my music does, in fact, have a bass track.
The quality is not "perfect" but car stereo cassette tape players never really purported to have perfect quality - and I think this adapter gives me the best I'm ever going to have on my car stereo.
