Portable cassette player Soundmaster RR20SI — FM/MW/SW radio, 3 W RMS, 3.5 mm headphone, Black/Silver

Soundmaster RR20SI is a portable cassette player with integrated FM, MW and SW radio bands and a 3 W RMS amplifier output. The device in black and silver is designed for playback of standard audio cassettes and for radio reception across FM, medium wave and shortwave bands. It accepts a 3.5 mm headphone connection for private listening and can be powered either from the 230 V mains (50 Hz) or by alkaline batteries, making it suitable for use at home or when travelling.

Advantages

A 3 W RMS output provides clear sound for small rooms and personal listening, while the 3.5 mm headphone socket allows private use without external speakers. Dual power options — mains and battery operation — increase portability and usability in locations without a power outlet. The black and silver finish delivers a neutral, practical appearance that integrates easily with different interiors.
