The Elite Strap with Battery & Carrying Case is my go to headstrap for the Quest 2. Without a doubt it is a pricey accessory, but it solves two of the major pain points of the Quest 2: comfort and battery life. The accessory helps to balance-out the Quest 2 that is normally very front heavy. The battery that is built into the back of the strap adds at least 2h of additional battery life, bringing the Quest 2 to a total of around 4h. On top of that you get a very stylish carrying case that offers enough space for the Quest 2 with this headstrap attached and the controllers.
