I have a Lightspeed 15XLc that I am selling. I have used it for about 6 months and it works great and has no cosmetic flaws.
If you don't know a lot about this headset it has 18db of passive noise cancellation and 20db of active noise cancellation. It a also has a hookup for anything with an audio jack (Ipod, cell phone, etc...).

It sells for $379 new I will sell it for $200. If I don't get any responses by the 12th or 13th I will put it on Ebay.
