D-111

The D-111 is the budget model in Sony's early electronic shock protection family, built to bring skip resistance into the lower end of the range without carrying over every premium extra. It omitted things like the cabled remote and rechargeable battery options, but still delivered basic ESP and Mega Bass on the same general platform as the D-211 and D-311, with lighter construction and simpler execution aimed at ordinary buyers.

By 1992, anti-skip no longer had to be reserved for the top of the line. The D-111 makes sense as part of the push to normalize modern portable CD across the entire range instead of keeping real mobility as a premium privilege. That shift did a lot to change what a Discman was expected to be.
