Remember the new dual drivers from Brainwavz we talk about a few weeks ago? It will be released at the end of April and MP4 Nation is having a promotion now. If you pre-order it, you will get a $30 off from the usual price of $169.50. There is another extra $10 off for those who had bought any of the previous Brainwavz models before, so check out the B2 page for the detail.
