MSI releases an update to their SteelSeries Siberia V2 Headset, this one is a special MSI Dragon Army Edition. The SteelSeries Siberia headset is one of the better headsets in its categor, that much is true. The headset was already released a little while agao, but just went live again on the MSI press website.
These headphones use the passive noise-cancelling technology, which means that they solely rely on their shape and build to prevent outside noise from reaching you. The passive noise cancellation is not nearly as effective as the active kind, but for the purposes of these headphones that might be a good thing.
