Always so practice this kind of device!

Hum well for elderly used cars ... they are always cassette radios!
No kidding, I also CD player.

But still away from the era of MP3, this accessory allows to the music of his player / smartphone on the radio ... and right away, it changes everything!

Simple to operate, sound quality, Sony branded as you plug headphones into the audio device, and cassette level, everyone knows ^^ put a cassette.

For the rest, that is our wheel spin in a vacuum makes some noise (this is normal ... it remains a "cassette player"), but the sound quality is all.

So no relation to the comments that judge this device have poor sound ... The sound is very well broadcast my smartphone to the car radio.
I am very satisfied with my purchase;)
