I previously had in-ear headphones from Shure. But I found the onset of headphones there bit annoying (you have the cable there "wrap" over the ear) and the handset cable after just over three years broke awkwardly, I have times with the "Sony MDR-EX 500 Premium "attempts. In addition, the customer reviews were so overwhelmingly positive. Unfortunately, at these headphones but absolutely nothing "Premium": 1. You sit extremely uncomfortable in the ear and press just a few minutes. 2. shield poor so that others can hear always, what I hear. You can easily chat with someone while you have the headphones in your ears. For in-ear headphones unacceptable. 3. The sound is quite cheap and thin. Spasmodic bass and treble to be strengthened. For fans of Karstadt-techno music certainly adequate, but for the most demanding music fans an imposition.
For someone who umsteigt of the typical headphones on in-ear headphones, the sound may be ok. For someone who is accustomed to quality, these headphones will not sound good enough. Shure there in this price range similar products that sound much better.
