I bought this to replace my headset unfortunately broken Hama CS-499 (1 € cheaper than this). But unfortunately, the HS-55 to classes worse than the CS-499th The sound from both the microphone and the headphones was dull, too quiet and no momentum. I use it mainly for Skype, but for the HS-55 is not to be used. Since I recommend as long as the available rather Hama CS-499
