By cons for headphones that's not it at all. I tried everything like headphones, since I tend to leave them lying around and my dog loves to play with .... But there are bad ones.
They do not fit in my ears, they even hurt me, I always feel that they are too depressed. No interchangeable tips, so that's the big negative is it going or you do not.
Then of course the sound. But as I regret my Sennheiser for only a few euros more! No low for its Sony, the sound is very clear it's even an earache I had to change my settings on my cowon but it does not change trop.Evidemment I am disappointed, my Sony headphones come with my old MP3 player of same brand were better it is to tell you! I hope my dog will quickly use it as a toy so I quickly buys more!
