Would be a combination of all 3. Primary use would be as a replacement for my HD598s when gaming but I also do enjoy listening to music and binge watching random Netflix series.
Perfect then as it does all three. These are made by Audeze and they are magnetic planar tehnology. It has an excellent mic, has AMP & DAC specified by Audeze and these things go loud. They are wireless for music and films if your TV has bluetooth. The 3D surround sound is VERY good for gaming. It has headtracking so you can bind in game keys to headmovements.
Some may consider all this stuff on a headset to be trinket as gaming headsets ususally are, but these are designed by Audeze which are a premium brand. IF Audeze made these 100% in USA they'd be £800. They make the magentic Planars, DAC & AMP in the USA the rest is assembled in China under Audeze's QA. They update firmware in this headset and the app also. The EQ options are set by Audeze also so you can switch between 'footsteps' for games or 'warm' or 'music' for gaming.
Anything else you'll need an AMP & DAC to compliment a particular set of cans depending how sensitive they are, a mic. All done for you at Audeze which are a premium brand.
I bought these purely for gaming but found myself using them for music also as I'd never heard music detail and seperation before. I'm VERY pleased with mine. I went into Richer Sounds and tried on a set of Sennheiser HD800S's through a £2500 dedicated AMP..........Meh for the money. My hearing aint that good or I havent developed an ear for it. For £350 they are a steal.
