Very confusing Situation with devices

I am reaching out for any help or advice anyone can give as this issue is the most baffling thing I've ever witnessed and even after extensive research & attempts to fix the issues they still persist. I cannot find an answer anywhere for this.

System: Xbox one S

Devices effected: Xbox Wireless Bluetooth Turtle Beach Headset & Xbox Elite Series 2 wireless controller

For about most of the year now in 2022 my husband & I have been plagued by massive issues on the xbox one regarding Bluetooth Devices. We share the same xbox due to having to sell my own previously so we will split game time between the two of us. When I play my games I could be on from 8am in the morning till 5am the next morning heavily spaced into my games with no issues watsoever never a single interruption...HOWEVER when my husband is logged onto his account Bluetooth issues are insane. He will get on and the moment he tries to play any game the controller and headset will randomly disconnect every 2 seconds (not exaggerating either) he can't play a game for any length of time without the controller disconnect screen popping up. And most of the time the controller isn't even actually disconnected at all and is still on and running but the pop up won't even go away seemingly not even responding to him hitting the A button. And the other times because he hopped into a party and the headset has had the same pop-up the controller will actually fully disconnect for a few seconds and reconnect again. The headset will as well get the disconnecting pop up every 2 seconds any time he attempts to be in a party which causes it to disconnect the controller as stated above which in turn will make them both flash like crazy or the headset won't even warn him and just shut off before beeping and he will have to manually turn it back on even though the battery is fully charged and nothing is wrong with said headset.

It's become so bad he can barely get into games anymore it kills his mood as it would myself if I had such issues. But as I've stated before if I'm signed in I have no issues like this EVER. It only ever seems to happen to his account in particular which is just baffling to me. As I've found no other person having quite this bad of an issue isolated to only one account on the same system usually it effects the whole system.

However if I ever sign in locally with him and try to play with him and our friends ..all of a sudden now I have issues too and it gets so bad we can't even play at all together anymore aside from an extremely rare occasion which is really frustrating and upsetting.

I have attempted every solution or answer out there

We have done the following:

1. Reset device connections

2. Update drivers

3. Power cycle

4. Resync devices

5. Force resync with USB

6. Soft reset console (keeping games etc & full factory reset)

7. turning off all Bluetooth from nearby devices

8. Moving gaming location to another room

9. Putting barrier between xfinity modem & xbox to prevent interference

10. Looked for anything that may cause interference and remove them (there wasn't any)

11. manually forcing updates with cord from pc download or programs for devices

12. Moving closer to system

13. Cleaning out dust from system

14. Removing any devices from back of console plugged in

15. testing if I can use headset for party etc with no issues (there was never a disconnect on my account only his specifically)

16. removing all metal items from nearby (testing interference)

17. Removing any previous connection to PCs

Conclusions: NOTHING WORKED

I have no idea why his account specifically is having this issue ..but there's nothing wrong with the console if it was it would be effecting my account as well not just his.

This is a really weird phenomenon and really needs to be fixed because we can't afford to replace anything ATM and really don't want to get a new xbox till the xbox series x goes WAAY down in price as I personally have a LOT of physical disks in my collection and prefer them over digital plus we've spent a ton of money on these devices and everything else in the past.

If anyone has any answers you would be a godsend right about now. I would love if my husband could enjoy games again and use the things he paid for.

Sorry for how Long this post is BUT the more info the more likely someone can help I think.

I pray this ends for him soon or else he may not be able to game anymore.
