Is thiat new stereo headset worth getting?

Do you have the little audio connector - 3.5mm Stereo Headset Adapter Headphone - Might be worth given one of those a try

Keep in mind there are no surround sound headsets that work solely with the adaptor (e.g.: the polks, xo four, xo seven) . All you are buying is a good pair of normal stereo headsets with no sound processing unit in them. The old headsets that get surround
from the optical out will still be good and can get chat from the new adaptor. But otherwise I don't see the point in forking out hundreds for a basic set of normal stereo headphones.

I have ordered the xbox stereo headset, cheap, and will suffice.

Old controller required the stereo headset adapter to work with my headset. ( was a friends stereo headset adapter) so I thought i'd buy the new type of controller so as to not also buy the stereo headset adapter.

The new controller differences

3.5mm jack which is pointless

and the bumpers feel slightly different, but that just may be because i'm now used to worn bumpers on my old controller.

that's it

I would recommend the official Xbox brand stereo headset as it claims to be compatible with all xbox one wireless controllers:

It probably doesn't need the stereo headset adapter - but if you're going to buy this headset, better just buy the stereo headset adapter to get your other headsets, that you already own, to work properly

Same issue with iPhone headset. Audio works great, in party chat, others here high pitch whistle. While less than desirable, it may be that the adapter is not designed to work with inline mic's. Look at the last item in the list below. "Any 3.5mm stereo
headset (that uses the CTIA plug standard) can get stereo game audio by plugging into the adapter"

I hope that the headset can work.

From XBOX.COM Headset Adapter page:

For game audio:

- Legacy gaming headsets get game audio from the back of the console from the S/PDIF port or from your TV/receiver with RCA cables. Get chat audio by connecting the 2.5mm chat cable to the adapter

- New Xbox One headsets – get chat and stereo directly from the adapter. No need to connect anything to the console

- Any 3.5mm stereo headset (that uses the CTIA plug standard) can get stereo game audio by plugging into the adapter
