Cheaper yes, but the entry level for BT is still pretty accessible. Using Google Shopping, the lowest priced match for "wired earbuds" is $1.47. The lowest priced match for "bluetooth earbuds" is $2.46. In both cases, you hit a breakpoint of "this looks like it might possibly work for more than a few seconds" around $10.

The battery point is valid. Funnily enough, the last pair of earbuds I lost was a wired one. Myself, most of my headsets are over-ear, so they're a bit large to be easily lost. The form factor likely determines the loss potential more than the presence/lack of a wire.
