FM Radio 31
The Silentex FM Radio 31 is an excellent choice for extremely noisy work environments due to its high and efficient attenuation. The high quality sound reproduction, the soft padded headband and the comfortable ear cushions make the FM Radio 31 pleasant to wear also over longer periods. The memory for last selected settings conveniently applies the last channel and volume level setting when the FM Radio is newly turned on. Its low power consumption combined with the rechargeable Li-ion battery offers very long operating time and eliminates battery costs. A low battery indicator informs the user when charging is needed and the battery is protected from discharging through automatic switch off.
