Sophisticated is commonly used as a comparison to other sinilar things. So a sophisticated computer in 1980 is different from one in 2026 because technology advanced significantly. A lot of common features on cell phones would have been called sophisticated 20 years ago, but not anymore.
In this case sophisticated is intended to mean relative to other similar devices. Since this is a commodity electronic device you can easily buy for under $13 it doesn't fit the common usage of 'sophisticated' for 2026.
