This model was a version of the WM-B52 fitted with an AM/FM stereo radio. Similar comments apply for both versions, though it is interesting to note that the radio version is no larger than the model without, though neither could be thought of as especially compact by Sony standards. The WM-BF58 effectively replaced the “floating” WM-F35, despite the fact that it did not float. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
