Part 2/7:
One noticeable change in the Aura Ring 4 is its smoother interior, which eliminates the raised areas where sensors used to be located. This redesign provides a more comfortable fit on the finger. Notably, the entire ring is made from titanium, contrasting with the previous version that only had titanium on the exterior.
While it retains similar color options as the Gen 3, the black version features a new glossy finish, adding to the ring's appeal.
