Bone conduction headsets have slowly gained traction in the market over the last decade. Despite technological improvements over multiple generations, the audio quality of in-ear devices that rely on normal air conduction is usually much better. Some vendors have realized the market opportunity in a device that can match desirable qualities from both types of headsets. The last few years have seen the appearance of open-ear air conduction / directional audio headsets that retain the situational awareness advantage (no ear occlusion) while also delivering better audio quality compared to bone conduction devices. One of the recent entrants to this segment is OneOdios OpenRock Pro. Read on to find out how it stacks up against the AfterShokz Aeropex (now Shokz OpenRun) that relies on bone conduction.
