I ordered this to replace an older headphone that had literally worn out. I didn't expect these to be as good as they have been. The stereo sound is terrific and very clear; the microphone is not intrusive while speaking. This headset is made to last and I couldn't be happier with my purchase. For such a low price I wasn't expecting this quality.
