On December 17, 2015, Entercom announced it would sell KRWZ to KSE Radio Ventures (a division of Kroenke Sports & Entertainment), who would add the station to its three recently acquired FM properties in the Denver market. KSE also announced that KRWZ would flip to a new format when the sale closes, as Entercom moved the Oldies format to KEZW on December 27. On the same day, KRWZ began stunting with mostly adult standards music, as well as redirecting listeners to KEZW. Upon the change of ownership, KRWZ would adopt the new KKSE call letters. Furthermore, KSE announced that the station would return to sports talk and become "Altitude Sports 950" (named after KSE's Altitude cable channel). This was followed by the flipping of country formatted KWOF to sports KKSE-FM.
