I've had the Hyper X Cloud II headset from Kingston for a couple of years. All-around a very solid headset, but for me in particular, they began to have a couple of big comfort issues -- the clamp would start to give me a headache after any sessions longer than 2 hours AND the heat that would build up on my head personally would start to get rather uncomfortable around an hour -- I had to lift them off my head pretty frequently (like between all multiplayer matches) every match, because I had become mentally conditioned to expect some level of discomfort from them. The problems with the headset might be mostly psychological for me, though, as I absolutely adored them and felt that the discomforts were extremely mild and non-problematic for the first 6 months or so that I owned the headset. I'd still highly recommend it.
I just replaced the Cloud II headset with the Steelseries Arctis 7 headset a few days ago. So far, I can say definitively that the sound quality is better -- both the game audio and chat quality, even if the wireless of the Arctis 7 headset doesn't work on Xbox One -- you'll have to use the included 3.5mm jack adapter and plug it into your controller. As far as I can tell personally, since I've just started using Dolby Atmos since I got my X, Atmos works fine on both headsets I've mentioned. The Cloud IIs can definitely handle left-right separation in Atmos very clearly but the vertical sounds are a bit weaker, whereas the Arctis 7 sounds like it just breezes right along just fine with the full range of Atmos. Again, however, I'm completely new to the tech, so I can't tell if they're doing great Atmos feedback, but it does indicate that positional audio is available in the Insects tech demo and I can definitely hear detect directional audio very clearly all around with the Arctis 7s, and I can definitely hear horizontal audio positioning very clearly with the Cloud IIs (and for the record, there is an audible vertical effect with the Cloud IIs as well, but it's a bit weaker than my Arctis 7s by comparison).
In my research that led to my purchase of the Arctis 7, I also noted that the Turtle Beach Stealth 600 and 700 get extremely good reviews and both support native wireless to the Xbox One -- no need for a dongle, it pairs via Microsoft's proprietary wireless, the same that the controllers connect to. I would have gone with the Stealth 600s myself, but I decided to try the Arctis 7s for the "ski mask band" format for head-fitting rather than the standard padded headband setup and the ventilated cloth they use on the earpads, in hopes of addressing some of my comfort problems. The Arctis 7s have been a huge comfort success so far and have proven to be a more pleasurable audio quality experience than my Cloud IIs as well (the clamp strength on the Arctis 7s as someone with a relatively small head is so loose that I feel like the headset could come off if I wobbled my head too much -- which is far more comfortable to me than getting a head cramp), but the Cloud IIs are still a rock solid recommendation. I would recommend looking at the Turtle Beach Stealth 600 and 700 if you're wanting to get a headset for an Xbox One only and don't mind a traditional head-fitting configuration, as the reviews for them seem pretty stellar especially at the price range and true wireless connectivity.
