The BOBOBVR M2 headstrap is a halo-style strap for the Quest 2. In the above video I am unboxing it and I compare it with my favorite strap, the Elite Strap with battery from Oculus.
In a nutshell: I am impressed with this strap! It is incredibly comfortable and makes the Quest 2 not feel front-heavy anymore! If only you would have a battery in the back, then it would be close to perfect! This is a headstrap that I can highly recommend. You can get it from Amazon here: https://amzn.to/2UpfWC7
