especially the clear audio. Telefonieren ist einfach. Youre getting this greenish, ugly splotchy pattern. Other than that the product seems great and holds everything pretty neatly. They also do not have a removable cable, which is a big downside. When I first received these they were very snug and I thought I was going to have to send them back, but after a few days they stretched out. It was difficult to assemble simply because it came with no instructions. I have the updated firmware Command Center and nothing Astro suggests helps fix this issue. Needless to say, dingus lost it. I used a Macbook Pro laptop and iTunes, I experimented with different Equalizer settings to get the best sound with each headset.
