The SRF-M10 was an FM-only radio of attractive design and very small proportions. The design emphasis was clearly on compactness and quality, though achieving these made the set quite expensive. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
The styling brought to mind some of the portable telephones sold under the Sony/Ericsson banner around this time, though of course the radio was much smaller. Having no AM band removed the need for a bulky ferrite bar antenna, and this along with the power requirement of only one “AAA” sized cell (which could last up to 40 hours) meant that the case could be made really small. Tuning was performed digitally and 15 stations could be stored in the memory. Control of the tuning functions was by a jog lever, similar to that found on some Discman models (e.g. the D-EJ885). Tuning information appeared on a miniature LCD screen, which unusually showed transparent characters on a black background. The display also showed the volume level (also controlled digitally) and when the set was switched off, a clock. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
The SRF-M10 was supplied with small in-ear headphones, but despite the set’s small size there was still enough room for a full-sized headphone socket, so other types could be used too. To make up for the shortcomings of some types of headphone, “Mega Bass” loudness could be switched in. The sensitivity of the receiver could also be varied, with “local” and “DX” modes being selectable by a small slide switch. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
There were a few omissions though, there was no backlight for the display, so under some conditions it could be difficult to read. There was also no way of switching from stereo to mono reception, so the listener could not reduce the background noise under difficult listening conditions. These small matters aside, the SRF-M10 proved that Sony was still very capable of making very desirable miniature products. Text copyright © Walkman Central. Unauthorised reproduction prohibited.
