You might be disappointed by a few of those items. Not trying to knock your purchases just sharing my experience with the quest and the MANY accessories I've bought.

In ear headphones aren't great to play with the quest imo. A lot of headset straps redirect sound from the quest right to your ears. At least it seems that way. Not sure if the BOBOvr one you bought does this.

Those KIWI controller knuckle straps block sensors and ruin some functionality. If all you need is knuckle straps i would recommend these. They replace the battery door and are very minimal but work great.

"Sweatproof" silicone face covers reallllly make you sweat. They are easier to clean but not nearly as comfortable as foam. Purely my opinion but this is the best face cover out of the several I've used.

The KIWI link cable will work just fine, but it might not have enough juice to charge your headset while you're playing VR linked to your PC. Also keep in mind you might not ever have to link cable to your pc at all. If you have good internet you can play completely wirelessly and it works even better than cable linked. I'm telling you this because I bought the ultra expensive $80 cable when I bought my Oculus because I didn't understand how everything worked.
