HTC Rezound is CDMA device released back in November, 2011 by HTC for Verizon. Initially the OS was Android v2.3.4 (Gingerbread) and later made upgradable to v4.0 (Ice Cream Sandwich). Although the official updates for HTC Rezound discontinued after v4.0, You can flash a custom ROM from below and enjoy Android KitKat on your HTC Rezound.
Please note that I did not test any of these ROMs. The links provided are from xda-developers.com which is a trusted source for Android development. Please refer to the original thread for instructions on flashing.
