watch the video in the link above. At the end it shows the adapter, and the cord on the headphones that you would plug in.

Hi Legend of RDG

If I understand your question...

Q: If you buy the Stereo Adapter, will this allow you to hear sound.

A: Yes, the stereo adapter will allow you to plug in headphones to hear sound. I omitted the headset that comes with the adapter just in case you already have headphones.

(The Xbox One Stereo Headset Adapter lets you plug a compatible chat or stereo headset into the Xbox One Controller to control your audio experience without taking your hands off the controller.)

The adapter will work with many existing headphones, but you can opt to buy the Xbox Headphones (w/Mic) and adapter too

Sounds coming from headphones and TV at the same time is normal for the console...the other day I left my stereo on (my TV is wired through it) and couldn't work out why the audio from my headphones sounded different!

As to the audio through a headset being lower quality, that would depend really....if the audio signal for the headset is coming directly from the Xbox (wireless headset or wired), then I'd argue it's better quality than that carried to the TV via the HDMI cable. For me, my wireless headset is plugged into my controller (using an adapter) and the sound quality is miles better than the TV is capable of (is even better than my very good stereo too)

If you don't have 3,5 mm jack in controller and no adapter, you can connect headphones directly to the TV, but you'll be only able to hear game sound.

If you have 3,5 mm or adapter :
