I've been using AfterShokz bone conduction headphones ever since I reviewed them in 2015 and they've become an inseparable part of my bike rides. The open-ear design allows me to pump up my soundtrack, while still being able to hear traffic and other goings on around me. Improvements have come incrementally with a few notable leaps, but the new AfterShokz Aeropex model seems to be the culmination of the past years' developments. It's lighter than the previous Air model (Trekz being dropped from the product name), with better sound and improved waterproofing which should keep them from being susceptible to repeated outpourings of sweat.
The new AfterShokz Aeropex is available starting today for $159.95. I've had the chance to use them for the past couple of weeks, so I can provide some perspective on how this new model works, especially in comparison to previous versions.
