I had in this price range already earphones from Sennheiser, Sony and Creative. And since my Sennheiser's were broken some time ago, I decided to look around for an alternative time. Then I got the Ultimate Ears discovered. I have to admit I'm not a professional hi-fi and sit down rather less deal with data and any values. I bought them at random - the price makes it possible! I was frankly surprised. Since I had the opportunity to make comparisons, I can say with a clear conscience that the Ultimate Ears my perception have by far the best sound, the best (low) bass and thus simply the best Prei for money. The heights are well defined and the depths discreetly but audibly. The Contras in the sense of "you hear every step", I can confirm that indeed, but have found a way this step sounds largely suppress. Werft have a look in the manual. There are two ways to be shown wearing the earphones. Once normal plugged into your ear, with the cable downward. The other (better) way, the earphones with the cord upwards and then the cable length out behind the ear cushions the step noise from such and also the noise which causes the cable if it somewhere comes off will be along the guide under the t-shirt (at backs) destroyed. Thus, you can see the added, existing Cons notice, but also defeat by simple means. The sound convinced just in full measure, so 5 stars.
