The EPOS H6PRO Offers A Choice
The Sennheiser and Demant Group created the EPOS line of headsets for audiophiles that want a bit more from their headsets than your average gaming ones. The new wired H6PRO series comes in both a closed acoustic model for those that like isolated audio and an open acoustic model which is lighter and allows you to hear what is going on around you. The two models are available in black, green and white finishes.
The wired H6PROs contains 42mm neodymium dynamic stereo drivers with a frequency response of 20Hz-20KHz and 28Ohm impedance, they differ in a sensitivity with the closed offering 117dB and the open at 111dB. The two models also share the same detachable bi-directional microphone with a frequency response of 100-10,000 Hz.
Nikktech spent a month with these two headsets to give them a proper workup, which you can check out here.
