I had to exchange my old good stereo headset with a new one. Because the old no longer because the cable for the microphone had wanted a break. At first I had my interest for a cordless system. There should be a 5.1 system, easy to carry and bring a good sound. All there was, unfortunately, not for my wallet. So I decided for og headset Speedlnk. Sure I've seen other reviews and was confused because often the word "scrap" was used. When I took the new headset from the cardboard box it was again folded in a pouch packed what impressed me ever. Better than this transparent supplied welded plastic mold doses. I had the USB connector plugged into a Penzio Port and it was automatically recognized by Windows Vista. but there was still no sound out. After driver installation and restarting the PCŽs I heard a slight crackling in the audience and I was bewust, now going kanns go. There should be a surround system so the illusion was first taken me because it was only in stereo and the microphone did not work on Teamspeak. After much trial and error and reading in various forums to confirm more and more the presumption that it is the USB port that does not want to play. Why he did not? It just lay on the supply voltage of the USB ports (Asus M2N32 Deluxe). That was too low and thus the headphones did not get enough power. Remedy could create as just a passive USB hub. After the stroke, the anschlisßen Höhrer went up in all its glory. Powerful sound and good dynamics have invaded my ears. TeamSpeak worked even now wonderful. Spielerein as Realtime echo or Mikimausstimme went well over Teamspeak. Music sounded good and the games sound is clear and clean. The processing of the headphones are good for the price and I can not understand how others get after a few days the things broken and because of, I'd say, clumsiness these headphones inscribedable immediately as scrap. There are nunmal headphones and any objects that are thrown in anger on the table, if you lose in a game.
