When we saw SteelSeries at this year E3 Expo, they showed us a variety hardware that is coming for the year.  We shared most of these new hardware announcements with our readers at the time, but there were some things the SteelSeries held back. Today we take a look at the SteelSeries’ answer for those gamers looking for a wireless headset.  The Spectrum 7xb is a variant of the stellar SteelSeries 7h gaming headsets that you see so many pro gamers using now.  With that kind of pedigree, the Spectrum 7xb headset is expected to deliver very accurate sound and overall sonic goodness.
