I am not sure if this counts but i have a Shokz OpenRun Pro bone conduction headset. Decent sound that keeps you aware of external sounds. Had mine for 1 and half years till one side no longer produced sound. Thanks to its 2-year replacement warrantly, I am waiting for the replacement unit to arrive.
The more moving parts you have, the more likelihood of repetitive use breakage. incidents include hinge loosening, display breakage at the fold. Also costly repair.
