Query: Call It An "Eh" Relationship

The Good;Works with any mp3 player or any device with a standard headphone jack.Can charge your mp3 player as you are listening to it.The Eh;Sound quality is NOT CD quality. Sounds more like an old tape.You have to turn your mp3 player and radio up pretty loud to get any sound.This transmitter has a really long cord. I'm sure it would be handy for someone, but that person is not me.The Bad;The display is not back lit. Very difficult to use at night.
