I used to date a Cowon A3 or a Cowon iAudio7 hardware player and since last time the Smartphon with the Cowon Software Player app "jetAudio Music Player". Can I recommend Traderjob. The sound with the J33 earbuds is much smoother, somehow it sounds very round, pleasant and fully balanced. The difference with the old was a revelation for me.
I hear rock, blues, rap, metal, etc. So across. What struck me is that these Gummiepropfen on listeners not as easy to drop like other I have already tried earphones lower classes. The premium class in my opinion rightly these earphones. If the earbuds do not fit correctly, there are still in the process different sizes for the rubber plug.
The main Bewertungskreterium is the sound for me! And this is extremely good. I would not even supposed to be so stingy and me to look around for what resonable, contemporary long ago. I would recommend this J33.
