What are you talking about. It has nothing to do with the speaker being too close to your ear, its because they were an awful design. Regular earbuds get the driver just as close and are still made, but arent very popular. The style has trended more towards in ear monitors because they seal your ear canal and get better bass. Due to the sealing IEMs are probably worse for your ears if you crank the volume but you probably don’t need to crank them as loud since they provide some passive noise cancellation.
