X2 Products comes to us from a team of PC enthusiasts based in the Netherlands. X2 has sent over for review today the X2 Aurel audio headphones with passive noise cancellation. Despite having an in-line microphone, the Aurel seem to be emphasized more for their audio headphone performance rather than portrayed as a true gaming headset. X2 advertises the Aurel series 2.0 as genuine audio headphones designed for style and functionality with gold-plated cables, passive noise cancellation and superb and crystal clear sound.
