I bought the first Aeropex model, then 1 year later this model.
The sound is I find much better in Aeropex, and the comfort on the ears is much better. This last remark is my own. For a use kit free hand I think on the other hand that they will go very well especially with the lower budget. For listening to music I advise to test the higher range.
I kept them 1 small moment and I already resold this model there to take again my old ones.
I bought this headset to use it when riding my bicycle. I expected that all this bone conductive thing is more marketing and I will not hear all sound frequencies. In the end I can say that the headset works really well. Sound quality is good (worse then in monitor headphones, but that's fine). I can still hear all environment and this of course affects sound quality. But this is what I agreed on buying such type of headsets.
Bought as a gift and the person really likes them. They are impressed with how well they works while running, etc. Their head is a bit smaller and the Shokz OpenMove isn't adjustable so sometimes it feels too loose.
