Bring broadcast listening and local media into one comparison with F50 4.3-inch and F51 7-inch screen-player options in gray or green. The source describes FM, MW and SW reception, Bluetooth, USB and memory-card playback, with different bodies and speakers for each size. Confirm supported files, radio bands and actual controls before purchase. Bluetooth-version, battery-runtime and display-resolution claims vary or lack tests; Wi-Fi music and wireless-speaker wording do not establish streaming or multi-speaker compatibility.
