15& unveiled their cover of Wonder Girls' "Be My Baby" as the first in the line up for their '15& SOUND' project.

Through '15& SOUND', the girls will cover songs by their JYP Entertainment sunbaes. 15& will sing the other JYP Entertainment songs with their own, relaxed style. They will be singing 5 songs for the next 10 weeks, with one new cover song being released every two weeks.

JYP Entertainment previously said, "Park Ji Min and Baek Ye Rin surprised everyone with their extraordinary vocal talents when they debuted in October. They have prepared a great event where they sing their sunbaes' songs in their own style. Please show them a lot of support."

Without further ado, check out their cover below!
