This list includes 3 hardware that can be done basically for free, and 1 tip that is well worth investing in.
1. The wrist strap mod.
This well known mod involves transforming the included wrist strap into a hand strap similar to the Valve Index controllers. With this simple mod you gain the understated ability to release your grip on the controller without it dropped down around your wrists - it is instead held in place on your hand!
To perform this mod you will simply need the included wrist strap and nothing else. There are videos on youtube which demonstrate the technique quite well.
My own personal take on this is to include a pair of elastic hair bands to provide a more springy, comfortable, adjustable, and flexible fit.
2. A VR Mat.
This concept is simple - a comfortable, padded mat, that also allows you to stay oriented in the center of your boundary area. This type of mat allows you to prevent a lot of accidents with swung controllers. It also helps combat VR dizziness, as you don't feel lost, you always know exactly where you are. While some great options available for sale from several companies, you can always create one yourself out of an old Yoga mat.
3. External battery.
If you've used your Quest 2 for any extended play sessions yet, you may have become frustrated by it's shortish battery life already. In some intensive games, I've found it to last less than 2 hours. However nowadays almost everyone has some type of battery pack kicking around. Even a measly 2500mAh that costs under $5 can add 2 hours of battery life. Something more decent like a 4800mAh is ideal.
The ways to carry around this spare battery are varied, from keeping it in your pocket and hacking the cable run up to the headset, to mounting the battery direct to the headstrap.
Although a 3rd party headset which includes battery is available, it's certainly not a requirement to extend your battery life.
Stay tuned for our future article on the most essential non-FREE but still highly recommended hardware and comfort upgrade that you can make to the headset.
