Our Verdict

Plantronics BackBeat Fit Wireless

AfterShokz Aeropex Bone Conduction

While the Plantronics BackBeat Fit Wireless and the AfterShokz Aeropex Bone Conduction look similar, the Plantronics have a more traditional earbud design that goes inside of your ear. The AfterShokz, however, are more comfortable, have better controls, and a better battery life. On the other hand, the Plantronics block more ambient noise and have a more neutral sound profile, which some may prefer. Some may also prefer that they have a more conventional earbud design, as opposed to the Aeropex, which deliver sound via bone conduction and sit outside your ears.
