Query: Don't buy

I had and used this headset for 2.5 years. It worked but the foam parts around the mic fell apart fairly soon. Now I finally bought a new no brand headset for $10, and I'm absolutely stunned at the difference in sound quality, particularly the mic. All those two years people had trouble understanding me and I always blamed everything but this headset. Logitech should be ashamed for selling such a low quality item.
