San Francisco’s Bay Area Rapid Transit District (BART) is warning commuters that Apple’s iconic white earbuds are magnets for thieves.

“Don’t be a target!” warns a BART flier distributed by at station entrances. “Use ear buds other than the standard iPod white, or other aftermarket headphones.”

About 1 out of 10 robberies on the BART system connecting San Francisco to the East Bay and region south of the city are iPod thefts, according to the flier.

“iPod theft is not unique to BART; it is a crime of opportunity occurring when an individual is seen wearing the familiar white iPod ear buds,” adds the flier.
