The MasterPulse PRO is USB powered and has an integrated soundcard to provide a virtual 7.1 surround experience as well as various preset EQ options. The frame itself has moved to the popular suspension style, which gives an interesting aesthetic appearance as well as being able to automatically adjust to the wearers head size. At its heart, the MasterPulse PRO is powered by 44mm drivers and features the patented Bass FX technology. This technology is effectively implemented in the form of magnetically removable side panels that alter the acoustic properties of the output audio. As this is part of the ‘Master’ series, these side panels can be customised by using the downloadable model so users can 3D print their own custom panels. Link
