I also had many positive opinions about the MX500 is one - so I was a little disappointed when I joined him for the first time on my MP3 player and penetrated somewhat tinny sound to my ear. Only after a few hours break-in period (just plug the earphone to any device and an extended period can play at a high, but not distortive, volume) and the attachment of the foam pad, which are hidden in the package, and round out the sound and give it more bass, is the tinny sound completely disappeared, and I am now very happy with the MX500! He now sounds better than any other I know of earphones is ideal to replace the miserable things that come with portable devices. I can only assume that the previous speakers have caught faulty handset, because any noise is never noticed me, quite the contrary: even at high volume levels (which you should not need to hear a long time) sounds the MX500 amazingly clear and free of distortion. Even the very practical volume control caused me no noise. At this price a must! The star's withdrawal just because the sound is just still something of "real" portable headphones away like the PX200, but the cost of maintenance also three to four times as much.
