Based on this list, you would think that in-ear noise-canceling headphones do not exist. That is simply not the case and the primary reason why they were not highlighted on this list is that over-ear models are typically preferred. In general, just by the nature of their design, they are able to cancel out more ambient noise. Yet, with that said, there are top-name brands out there that do make in-ear models (and some of them are quite good).
