Previously, I had about 10-year-old unknown brand InEars without microphone and control. They were not cheap, but not likely to have cost quite as much as the tested here Logitech UE 600vi. Used for comparison I still have the headphones from Apple, the iPhone 5 came with and it cost significantly less. The headphones from Logitech comes with various silicone and foam pads, there's really something there for each ear. The ear pieces have different colors and can be easily merhken because red is for right. At the cable is still a clip attached and on the control element with micro-there is a stop / play button and volume up and volume down buttons. These can be easily operated and react quickly. However, the microphone is not to be used because it is simply too far away. When I speak in a normal voice, I am no longer hören.Die cables of all three headphones have the same thickness, but I find the Überecklösung here unfavorable. I would imagine that could develop a source of error here. The box for storage is big enough. Once you have the correct buffer size ear found, the headphones sit very well and umbrellas also perform well. I hear a lot of opera and had therefore heard all three headphones arias from different operas. My Uralt headset and Logitech both suffer from the same disease: they rattle in the high notes. While perhaps is acceptable even when the headphones of the middle class, I am very disappointed with the Logitech. Here I would have been expecting a better sound quality. The remaining positions are highly differentiated and the bass are not too flat, but the clatter leads to the devaluation. Only the Apple headphones sounded really good, but unfortunately they still hold no spite of the changed shape in my ears.
