While I don't own a pair -yet- they're not on sale in the States, I have been using a pair of ATH-AD700 headphones for several years with an Astro Mixamp. I can speak to the comfort as these share the same design. They are the most comfortable headphones I have worn. I can play for hours and I don't think about them once. Conversely, the Astro A40 cans that I own have a more traditional headphone support strap and they get uncomfortable rather quickly. The weight of those headphones ends up being concentrated on the center of the strap and therefore at one point on the top of your head. The AT wing design distributes the weight to both sides evenly and there is no pressure felt on your head.
As for PS4 compatibility, these have a standard 3.5mm 4 pole connector and I believe the port on the PS4 controller is the same. These should work with the PS4.
When it comes to "pinpoint audio awareness", the specs on these headphones is very similar to the AD700, so I am assuming the sound stage will also be very similar. The sound stage on the AD700 is fantastic. When combined with a game that has great audio cues (read: Infinity Ward developed COD games and not Treyarch) and Dolby Headphone, the audio awareness is so good, it is almost like cheating. With the perk that enhances enemy footsteps, I can usually identify the direction and distance of enemy footsteps. So, the audio awareness is dependent not only on the quality of the audio cues built into the game, but the type of audio being fed to the headphones. It is my understanding the audio from the PS4 controller is currently stereo. So, the audio awareness, while better than anything you would be getting from the TV speakers or a sound bar, will not be quite as good as virtual surround sound. Although, I would not be surprised if Sony releases an update eventually that outputs their virtual surround sound through the controller jack.
