Arlan manufactures the ‘Radiosport’ line of phones and headsets in the USA. Experiencing the weaknesses of other products during his motorsport career in the 1990s, the founder of Arlan started to develop and manufacture his own line of headsets and phones for the professional customer. The products are characterized by an excellent robustness, good wearing comfort and a modular design.
The Arlan Radiosport RS-20S is a headphone for radio communications, for example for aviation, motorsport, short wave listening or the amateur radio hobby. The headphone is solidly constructed, for example the outer shells of the speakers are made from carbon fibre reinforced material. The headset frame is made from light spring steel which assures a good fit without too much pressure. By using thick, gel-filled ear pads the headphones sit very comfortably over your ears, while also offering a strong reduction of ambient noise by 24dB! This allows you to listen to a faint telegraphy QSOs even in the thick of a contest. The ear pads are additionally equipped with removeable, washable cotton covers.
The speakers have an impedance of 32 Ω, making it a good match volume-wise for standard radio speakers and desktop speakers. You Will not need to adjust the volume much when switching between speaker and headphones. Included in the shipment is a detachable cable with 3.5mm stereo phone plug, an adaptor to 6.3mm phone plug is also supplied. The RS-20S headphones weigh c. 480g.
