Offer the Elite Headstrap WITH battery, but WITHOUT the carrying case OR offer the battery seperately.
I already have a carrying case and don't need another. I see that you can buy the elite strap seperately, but from what I can see, the only way to get the battery is in the bundle with the carrying case.
Anker 10,000 mAh with USB-C charge port, and works as an output as well. Just $26.00. I use the 3 foot cord to go to my sweatpants pocket and play Beat Saber for Hours between the two charges. No extra weight on my empty head either.
Head Strap Clone was $40.00. It's OK...
