The overall shape is similar. However as a consumer, I would love it if every universal IEM maker used this design because it fits so perfectly in my ears with the maximum about of internal volume to house multi drivers while not sticking out too much. That's the main reason I want to try the FH15. Do I think FiiO copied the design? They probably looked at a lot of competitors and picked this design so yes, but I'm sure JH did the same. Do I think there is anything wrong with it? No because for the most part universal IEMs fall into 3-4 generic shapes because of the way the human is generally shaped. There is nothing patentable about the design. Creating a shape that is going to fit 80% or more of the population of average person's ear shape does not give one much flexibility. It's only truly unique solutions like UE semi-customizable universal IEMs that get patents and cannot be copied without a license from UE. Having said that, is FiiO known to be an innovator in the IEM world? Not yet, but they are trying but also position their products to be affordable to the masses. Basically, FiiO doesn't compete in the space with JH, Noble, EE, and other established innovators so I personally don't see a conflict here.
