Looking to finally purchase a new pair for my PC gaming setup, the 2 that I have been narrowed my selection down to are the K702 and the HE-400i. Both are currently around the same price. This will be used on my home PC, which will be used for gaming 90% of the time. My biggest concern is to get the best competitive advantage in FPS games (I play PUBG, Overwatch, CSGO, BF1). I won’t be doing much listening to music or watching movies since I usually do those elsewhere. I have a dedicated soundcard so driving any of these headphones shouldn’t be an issue for me. The 2 headphones I currently have are the HD598 and the AD700, both of which have gotten a lot of praise as great gaming headphones. My major gripe with the AD700 is that although it has great directional accuracy, close sounds and far away sounds don’t have great separation and often gets muddied together and hard to discern when there is a lot going on. I found the HD598 to be better for my purposes, although the directional accuracy was a tiny bit worse, the sounds didn’t get muddied together and it did a better job of painting an image of my surroundings. I’ve been using these for a while now, got the HD598 about 5 years ago, and the AD700 maybe a decade ago, looking to try something new. Also how would those compare to their Massdrop counterparts (K4xx and HE4xx)? I wouldn’t be opposed to getting the Massdrop versions as well if they’re better for my purposes.
