If there is one upgrade that completely changes how VR feels, it is the head strap. Most stock straps are fine at first, but after a few sessions, the problems start to show.
These small issues add up fast and pull you out of the experience.
A better strap changes everything.
It balances weight evenly across your head
It stays secure without tightening uncomfortably
It lets you forget about the headset and focus fully on the game
If you get one with interchangeable batteries, the difference becomes even bigger.
You can play for hours without worrying about power
You never have to stop mid-session to recharge
The weight of the rear battery improves balance and comfort
That is why this is the first upgrade I always recommend. A comfortable, balanced headset is the foundation of every great VR setup. Once it feels right, everything else—immersion, control, and focus—comes naturally.
