Reddit mentions of Microsoft Xbox One Stereo Headset Adapter

So in terms of sound, you can attach headphones straight into the aux jack on the controller if you have a newer one, or buy a headphone stereo audio adapter if you have an older controller and the headphones/headset plugs into that and gives you both game sound and voice chat.

Monitor wise, get anything with under 5ms response time and you only need 60hz refresh rate as Xbox can only display a maximum of 60 frames per second (fps) so don't listen to anything trying to suggest you need a 144hz monitor as this is just a waste of money for a console, brands like BenQ, Asus, Samsung all make very nice monitors, I'll link a few below, note they will be UK links to Amazon as that's where I'm from.

Note the bottom one, the Samsung, does have speakers, so for this one you can just plug the HDMI in and use the speakers from the monitor, or turn the volume down to nothing and use headphones if you would prefer.

BenQ

Asus

Samsung

You'll need to add this to your controller if its not one of the latest, It allows you to add pretty much any headphone/earbuds with or without a microphone.

Dude, these are the two things you need to get your XP400's working with the Xbox One without the need for using two different headsets:

• Xbox One Stereo headset adapter
  
  
• Turtle Beach PS4 Chat cable for XP400
  
  The PS4 cable is compatible with the Xbox adapter (They use the same 3.5mm CTIA standard jack)

I would suggest the hyper X cloud 2. I have had headsets that are cheaper and headsets that are several hundred dollars more (Astro) and I can assure you the sound quality is on par with more expensive headphones, the comfort is the best in gaming headset, the mic is also really good both in sound and in convenience as it's removable and easy to reposition. also the convenience of having the USB sound card in case you ever want to use it on PC is a nice bonus. Even the packaging is top notch lol.

You will want the headset adaptor for the controller though as it is easier to adjust volume settings (although this can be done in the guide)

14.99 Amazon UK for the headset adaptor

Any Xbox compatible 3.5mm Jack headset can be used with the official Xbox One Stereo Headset Adapter. They are about £16 ($20?) on Amazon (https://www.amazon.co.uk/Official-Xbox-Stereo-Headset-Adapter/dp/B00I41H7US/). This plugs into the rectangular port on the bottom of the controller, and gives you mute, chat / game balance, and volume up / down buttons. It's very simple to use, and gives you full control over the volume balance for game and chat.

You can also get aftermarket pads from PDP, which have a 3.5mm socket for any Xbox compatible headset with a 3.5mm Jack, and they have a special dedicated button by the right thumb stick, which when double tapped, mutes the mic, and when held down, turns the D-Pad into a volume up / down and chat / game balance control.

This is what I use, and it is so easy to adjust game and chat volume on the fly, I'm actually surprised MS don't do something similar - it's such an intuitive way of doing it. One thing though, is that I don't know whether PDP do a wireless pad with this feature, (I'd have to google it) as the ones I've seen on Amazon are wired (as is mine). They are only about £35 / $40 or less though, and the cable means the controller is light, and never runs out of battery! :D

Edit - Had a look and can't find a wireless version, but this is the one I have, and I am very pleased with it, cable is nice and long, and fits securely. It feels a bit different to a regular controller, some things better, some things worse. The home button is much easier to use, but the triggers are flatter. Buy from Amazon with free delivery and try it? https://www.amazon.co.uk/Afterglow-Prismatic-Wired-Controller-Xbox-x/dp/B00ZJRHSRW/

Do you have the Xbox One already? If you buy it brand new, the controller will have the 3.5mm socket already, but for some reason it doesn't like the QC35's and you have to plug it in really, really slowly (it's best to have some audio playing like a title screen of a game so you can hear the music pop in) but if you want to save that trouble here is the Stereo Adaptor and here is the QC25 Android Cable i purchased, i can assure you that it works. and yes the microphone works too.

If you look closely at the plug you'll notice there are 4 separate metal contacts (TRRS) instead of 3 (TRS) see this image

That extra contact is for the microphone, smartphones can utilize this as standard, letting you make hands-free calls, but will need an adapter cable to work on separate headphone and mic jacks on a PC (like this)

As for the xbox, depending on which you have there adapters for those too, this for xbox one controllers and a combo of this and this for an xbox 360 controller

As for whether you'd be better off with separate headphone and mic, absolutely, of course you would be, I can't imagine polaroid branded headphones sounding any good at all, yes they are indeed usable for all your intended applications with the adapters I linked but sound quality will be poor, especially mic quality from the tiny thing built into the cable. If that bothers you in any way, then head over to the sticky thread for advice on what to get instead, otherwise those adapters should work fine, even if they come in at just as much, if not more than the headphones cost themselves.

Want a 3.5mm audio jack on the controller? That's another £20.

The adapter usually comes with xbox one compatible headsets. It can also be purchased separately and used with pretty much and headphone with a 3.5mm jack.

Would have to get from Amazon UK, links I'll buy at below:

Stereo Headset Adapter plugs into the controller you then plug any headset with a 3.5mm cable into that and get audio wirelessly through your controller.

Other option is if you have a pair of speakers with a 3.5mm or RCA jacks on it to then buy a DAC Digital SPDIF converter. This is USB powered and plugs into your Xbox One SPDIF port, you then plug your speakers that either have a 3.5mm plug or RCA jacks into this and voila you get audio out of your speakers without the need of having to use headphones or a stereo headset adapter into the controller.

Sure!

Optical to RCA Adapter

Chat Adapter

Optical cable

It sounds way more complicated than it is, just connect everything up all fine and you're good, I even think running the x12s through Optical instead of just RCA makes them sound a lot better, but that could just be me.
